2. The HCVR-3 is UL 864, 9th Edition Listed.
Introduction
This presentation is designed to give you a technical overview of the HCVR-3 Conventional Releasing control panel.
Always refer to the HCVR-3 Installation and Operation Manual for details
regarding the installation, programming, operation and servicing of the
Product (HA ).
The HCVR-3 is a three-zone conventional releasing fire alarm control panel.
The HCVR-3 provides connections for Zones, NACs, a Releasing Circuit, Relay Outputs and more. Indicators and control buttons provide an effective user interface to the system.
The HCVR-3 is UL 864, 9th Edition Listed.

3. There are various models of the HCVR-3 control panel:
HCVR-3-R (115V)
HCVR-3-R (230V)
HCVR-3-C (115V)
HCVR-3-C (230V)
HCVR-3 accessories include*:
HCVR-SDU Status Display Unit
HCVR-AS Abort Switch
HCVR-SQA Sequential Activator
HCVR-AB Ancillary Board
R = red. C = charcoal. 115V and 230V specify the input voltage.
Max # of status display units and/or ancillary boards = 7
The ancillary board contains 10 relays which are preconfigured to indicate the status of things such as the 3 zones, automatic/manual operation of the panel, disablement, release, manual release, etc.
* There are color and build versions for some of these accessories.
Check the HCVR-3 I&O for details on exact model numbers.

4. Some additional features include:
Cross-Zone operation for releasing verification
Releasing Delay up to 60 seconds
Abort function using the HCVR-AS Abort Switch
Disable Zones function
500mA of auxiliary power available
1 amp of releasing power available
1 amp of NAC power available on NACs 1 and 2
Diagnostic LEDs assist with troubleshooting.
Total PSE power must be managed so that power supply limits are not exceeded.
Programming is easily and quickly accomplished using front panel controls.

5. The HCVR-3 has three conventional zones and three NACs.
System Planning
The HCVR-3 has three conventional zones and three NACs.
NAC 3 is designed to indicate pre-release and release conditions. You will only connect releasing notification appliances to this circuit.
A Manual Release switch is located on the front of the HCVR-3.
NAC boosters can be used if more than two NACs are needed – see page 28 of the HCVR-3 manual, V2.10.
This suggests that the HCVR-3 is intended for smaller areas and, ideally, should be installed nearby where the extinguishing agent is to be discharged.

6. System Planning
If you are using cross-zoned smoke detectors for the purpose of automatic releasing be aware of the following:
(NFPA 72, 2013 Edition) Systems that require the operation of two automatic detectors to initiate the alarm response shall be permitted, provided that the following conditions are satisfied:
(1) The systems are not prohibited by the authority having jurisdiction.
(2) At least two automatic detectors are in each protected space.
(3) The alarm verification feature is not used.
(NFPA 72, 2013 Edition) For systems that require the operation of two automatic detectors to actuate public mode notification, the detectors shall be installed at a linear spacing not more than 0.7 times the linear spacing determined in accordance with Chapter 17.
and are from NFPA 72, 2013 Edition
is from UL 864, 9th Edition
* In the absence of specific performance-based design criteria, one of the following requirements shall apply:
(1) The distance between smoke detectors shall not exceed a nominal spacing of 30 ft. (9.1 m) and there shall be detectors within a distance of one-half the nominal spacing, measured at right angles from all walls or partitions extending upward to within the top 15 percent of the ceiling height.
(2)*All points on the ceiling shall have a detector within a distance equal to or less than 0.7 times the nominal 30 ft.
(9.1 m) spacing (0.7S).
A The 30 ft. (9.1 m) spacing is a guide for prescriptive designs. The use of such a spacing is based upon customary practice in the fire alarm community. Where there are explicit performance objectives for the response of the smoke detection system, the performance based design methods outlined in Annex B should be used. For the purposes of this section, “nominal 30 ft. (9.1 m)” should be determined to be 30 ft. (9.1 m) ±5 percent [±18 in. (460 mm)].
A (2) This is useful in calculating locations in corridors or irregular areas [see and Figure A (h)]. For irregularly shaped areas, the spacing between detectors can be greater than the selected spacing, provided the maximum spacing from a detector to the farthest point of a sidewall or corner within its zone of protection is not greater than 0.7 times the selected spacing (0.7S).
Alarm activation that requires the activation of two automatic detection devices shall not utilize the alarm verification feature or any other time delay.
Guidelines, instructions, and restrictions [such as spacing, alarm verification feature, and/or other time delay(s)] for the installation and use of a system employing multiple detector operation shall be included in the installation wiring diagram/instructions.
90.19 (UL 864, 9th Edition) Units employing the multiple detector operation described in and shall include guidelines for installing of a minimum of two detectors in each protected space and to reduce the detector installation spacing to 0.7 times the linear spacing in accordance with National Fire Alarm Code, NFPA 72.

7. What does this mean to us?
System Planning
What does this mean to us?
You must install at least two detectors in the protected space (two different zones of the HCVR-3 panel)
The detector spacing must be no more than 0.7 times the linear spacing (if public mode notification is used).
“A” and “B” on each detector indicates how the zones should be alternated – for example, all the “A’s” are in zone 1.

8. System Planning (almost done)
You must install the HCVR-3 in accordance with NFPA 72, NFPA 70 and all local codes.
If you are using FireNET Xtinguish, additional codes and requirements will be involved!
See Appendix C of the HCVR-3 I&O for battery and maximum wire length calculations.
Do you need:
An Abort switch?
A Manual Release switch other than the one on the panel?
NFPA 72 – National Fire Alarm and Signaling Code
NFPA 2010 – Standard for Fixed Aerosol Fire-Extinguishing Systems
To comply with NFPA 72 and NFPA 2010 requirements, you must install a supervised disconnect switch on the releasing circuit.

9. System Planning (almost done)
The minimum required documentation (Chapter 7) includes the following:
Written narrative providing intent and system description
Riser diagram
Floor plan layout showing location of all devices and control equipment
Sequence of operation in either an input/output matrix or narrative form
Equipment technical data sheets
Battery calculations
Voltage drop calculations (NACs and releasing circuit)
And there is more…
From NFPA 72, 2013 Edition
Thorough planning is important.
It can help avoid problems later in the process.

10. Section 3 of the HCVR-3 I&O explains the steps to install the panel.
Installation
Section 3 of the HCVR-3 I&O explains the steps to install the panel.
To mount the panel, remove the fascia and securely mount the cabinet to the wall.
Next, connect the AC power, re-attach the fascia, and make the other connections.
Use one of the knockouts on the left-hand side of the enclosure for the AC power wires.
Local codes may require that a licensed electrician connect the AC power for you.
For convenience, the 24V DC terminal block is removable.

11. Installation
All circuits of the HCVR-3 Releasing Fire Control Panel are power limited except the AC input circuit, transformer input and output, bridge rectifier input and output, and the battery.
For proper operation and compliance with the National Electrical Code, you must maintain a minimum ¼ inch spacing between power-limited and non power-limited circuits.
See of NFPA 70 for the ¼” spacing requirement (2011 Edition)

12. Tip: Be sure the batteries are marked
Installation
The panel should be mounted in a clean, dry area where it will not be subject to shock or vibration.
The circuit board of the HCVR-3 is vulnerable to damage caused by electrostatic discharge. Use a ground strap when handling the board to prevent such damage.
Two 7Ah sealed lead-acid batteries provide standby power for the panel. The batteries must be connected in series, as shown here -
The “tip” comes from NFPA 72, section
Marking.
Batteries shall be marked with the month and year of manufacture using the month/year format.
Where the battery is not marked with the month/year by the manufacturer, the installer shall obtain the datecode
and mark the battery with the month/year of battery manufacture.
Tip: Be sure the batteries are marked
with the date (month/year) of manufacture.

13. Remote Control Inputs NOT USED
Installation
The HCVR-3 has connections for the detection zones, supervised inputs, NACs, releasing circuit, relay outputs, 24VDC aux power and status units
Remote Control Inputs NOT USED
NAC 1 and 2
NAC 3
Supervised Inputs
Relays
24VDC AUX Power
500 mA maximum
Status Units
For HCVR-3 accessories
Zones 1 - 3
1st / 2nd Stage relays
EXTING Circuit
Status units include the HCVR-SDU Status Display Unit and the HCVR-AB Ancillary Board.
NAC 1 and 2 – special application 500mA continuous / Regulated mA continuous. Class B Style Y only.
NAC 3 has same ratings but can only be used for releasing notification.
1st Stage Delay – when the first zone of two cross-zones goes into alarm; 2nd stage delay is when the second cross-zone goes into alarm.
Supervised inputs need 470 ohm resistor in series with the N/O contacts. Mode Select is not used (it changes the mode from “Auto & Manual” to “Manual Only”
EXTRACT is a N/O contact. The intention is to control a fan to vent releasing gases from a room. It is manually controlled from the level 2 menu, option Ac.

14. supply are labeled ( + ) and ROV. ROV is the negative terminal.
Installation
The AUX 24V connection is a common special application output. The output is supervised for short-circuits and ground faults. The output is not supervised for open circuit conditions. Terminals of the Aux 24V
supply are labeled ( + ) and ROV. ROV is the negative terminal.
The AUX 24V supply is protected by an electronic, self resetting
fuse. Devices connected to this output must not draw current
in excess of 500 mA.
Status Unit terminals of the HCVR-3 panel contain connections for Data and Power. The Data terminals provide RS485 communication.
The Power output of these terminals is designed to
operate the Status Unit and the Ancillary Board only.
The “STATUS UNITS” Power connection is rated for VDC.
Status Display Units require 50mA (each) in normal standby and 94mA (each, maximum) in alarm.
Ancillary Boards require 16mA per board in normal standby and 175mA per board maximum in alarm.
A common earth ground is required between all Status Units and the panel.

15. The output of NACs 1 and 2 provide a steady voltage during alarm.
Installation
The output of NACs 1 and 2 provide a steady voltage during alarm.
Listed NAC boosters may be used on NACs 1 and 2 as long as they operate in the range of 18 – 28 VDC and draw less than 500 mA.
NAC 3 may only be used for releasing notification. The output is pulsing during the delay phase, and continuous after the extinguishing agent has been released.
Each NAC is terminated with a 10K ohm end of line resistor (EOLR).
Maximum current per NAC = 500mA.
Zones of the HCVR-3 Releasing Fire Control Panel operate NFPA 72 Class B, Style C or NFPA 72, Class B, Style B.
Style C circuits provide trouble conditions for direct shorts and opens on zone loops.
(Class B Style C last appeared in the 2002 Edition of NFPA 72. Style C was removed from the 2007 (and future) editions of the NFPA 72 code because this circuit style is not commonly used in systems today. Only Class A and Class B remain for IDCs. Style C does, however, still appear in the 9th Edition of UL 864 – see Table 51.1.)
Style B circuits provide alarm conditions for direct shorts and trouble conditions for opens on zone loops.
Zones provide a nominal 24 VDC for powering conventional two-wire detectors. Each class B zone requires a 6.8K ohm EOLR.
Zones may be configured Style B or Style C.

16. This is the circuit configuration:
Installation
The supervised inputs of the HCVR-3 are Class B Style C circuits*. The inputs generally used are Abort and Manual Release.
This is the circuit configuration:
A 470 ohm trigger resistor is installed in series with the switch, as shown here.
For correct operation, the supervised inputs must be wired in this manner.
The other supervised inputs are REL PRES. SWITCH (which indicates ‘Extinguishant Released’ when activated), LOW PRES. SWITCH (which results in General Trouble, Releasing Trouble and Low Pressure indications), and MODE SELECT which is not to be used (but when activated it changes the mode of the panel from Auto & Manual to Manual Only).
Class B Style C last appeared in the 2002 Edition of NFPA 72. Style C was removed from the 2007 (and future) editions of the NFPA 72 code because this circuit style is not commonly used in systems today. Only Class A and Class B remain for IDCs. A Style C circuit will indicate a trouble on open and short.
The relays are rated 1 amp maximum.
*A Class B Style C circuit is no longer identified in NFPA 72. However, this circuit is still referenced in UL 864.

17. Some additional facts:
Installation
Some additional facts:
The terminal blocks accept wire sizes from 14 to 18 AWG.
The AC fuse is 1.6 amp slow-blow. The battery fuse is 3.0 amp, slow-blow.
The maximum line impedance for the initiating circuits is 20 ohms. See Appendix C for instructions on how to calculate the maximum wire length for the NACs.
The total resistance of the EXTING circuit must be no more than 9.7 ohms.
The control panel requires 100mA in NSC and 620mA maximum in alarm.
The maximum power supply current is 2.0 amps. You must manage the available power to ensure that the total current draw of the system – including the panel itself – does not exceed 2 amps.

18. Let’s take a look at the indicators on the HCVR-3 panel.
Panel Indicators
Let’s take a look at the indicators on the HCVR-3 panel.
The manual refers to these as the ‘Upper Indicators’. Most of them are self-explanatory.
If part of the system is disabled, the General Disablement LED will illuminate along with an LED that describes what is disabled.
For example, if the EXTING output is disabled, the General Disablement and Extinguishant LEDs will be illuminated.

19. 1st Stage Activated indicates that the first cross-zone is in alarm.
Panel Indicators
1st Stage Activated indicates that the first cross-zone is in alarm.
Release Imminent indicates that both cross-zones are in alarm and the panel is preparing to release the extinguishing agent.
The Low Pressure LED is illuminated in response to the LOW P. SWITCH input.

20. Additional information is contained in the HCVR-3 I&O manual.
Panel Indicators
When the key is set to Manual Only, the EXTING circuit will not operate in response to alarms from the zones.
Additional information is contained in the HCVR-3 I&O manual.

21. How about the lower indicators on the panel?
Panel Indicators
How about the lower indicators on the panel?
These provide greater detail about panel conditions. When the front door to the panel is closed, these indicators are not visible.
These indicators are all reasonably self-explanatory, with the possible exception of “Tell Tale”.
When illuminated, this means that a manual release took place!

22. We will discuss this in greater detail when we review programming.
Panel Indicators
The Central Indicator is an LED display. It is used for programming and to identify status conditions.
We will discuss this in greater detail when we review programming.
As with the indicators, there are upper, central and lower controls. The upper and central controls are visible when the panel door is closed.

23. Controls
The Mode, Select and Enter buttons are used for level 2 and 3 configuration and programming.
There are five lower controls. These can only be seen when the front door to the panel is open.
Terminate Release – resets the EXTING circuit back to the non-alarm state.
Note: Pressing the Reset button while the EXTING circuit is activated will not cause the circuit to shut off. You must press the Terminate Release button if you wish to shut off the activated EXTING circuit prior to the auto-shutoff time.
If you wait for the EXTING circuit to automatically shut off, the Reset button will clear the alarm and return the panel to normal standby when pressed.
To illustrate…
THIS ONLY APPLIES WHEN AUTO-SHUTOFF TIME IS USED! The EXTING circuit may be configured to remain ON until the panel is reset. In that case, the panel and EXTING circuit may be reset anytime by using the panel reset button. See programming option C2b.

24. The zone alarms will be cleared when the Reset button is pressed.
Controls
If the Reset button is pressed anytime during “A”, the EXTING output will remain on. It will automatically shut off at the end of the auto-shutoff time.
The zone alarms will be cleared when the Reset button is pressed.
The Extinguishant Released, Release Imminent and 1st Stage Activated indicators will remain illuminated. To clear them, press the Reset button again anytime during “B” (after the EXTING output has shut off)

25. Reset the panel to return it to normal condition.
Controls
If the Terminate Release button is pressed anytime during “A”, the EXTING output will turn OFF immediately*.
All LED indicators will remain illuminated. Only the System Mode display will clear.
Reset the panel to return it to normal condition.
* The Enable Access key does not need to be ON for the Terminate Release button to work.

26. EXTING. Mon. – used to calibrate the releasing circuit on the panel.
Controls
The Watchdog Reset button is used to clear a Watchdog event. These events occur if the panel
fails to execute its
program properly. Such
events are uncommon.
The Processor Reset button reboots the HCVR-3 processor. This button is also used to clear the “Tell Tale” LED after a manual release event has occurred.
At times, when the Processor Reset button is pressed it may cause a Watchdog condition. This can be identified by an illuminated CPU Trbl. LED and continuous buzzer. Press the Watchdog Reset button to clear the condition and restore the panel to normal operation.
EXTING. Mon. – used to calibrate the releasing circuit on the panel.
Write Enable – used to access the programming options

27. How do I calibrate the EXTING Releasing Circuit?
Controls
How do I calibrate the EXTING Releasing Circuit?
…and when should I do so?
You should calibrate the EXTING circuit every time you install a HCVR-3 panel.
Three easy steps:
1 – With everything connected to the EXTING circuit, does the panel show a Releasing Trouble? If it does, turn the Exting Mon. adjustment clockwise until the trouble clears.
If the type or number of devices on the EXTING circuit is changed, the calibration must be checked again. If the panel does not indicate trouble as it should, the calibration must be done to account for the change to the circuit.
2 – Disconnect the EXTING circuit wiring. Does the panel show a Releasing Trouble? If it does not, turn the Exting Mon. adjustment counter-clockwise until the trouble appears.
3 – Reconnect the circuit and turn the Exting Mon. adjustment one full turn clockwise.

28. Other Installation Notes
An HCVR-AS Abort Switch may be connected to the ABORT input of the panel.
When the releasing conditions have been satisfied and the panel is counting down to activate the EXTING circuit, the Abort switch will halt the countdown at 10 seconds.
As long as the Abort button is depressed, the countdown will remain at 10 seconds and the EXTING circuit will not activate.
If the button is released, the countdown will continue from 10 seconds to 0. The button may not be used a second time! To stop the release, the panel must be reset before the 10-second timer expires!

29. Other Installation Notes
The Abort switch is a normally-open momentary push button.
A 470 ohm trigger resistor must be used for the Abort circuit.
The connections on the switch look like this -
The circuit is wired like this >
The Status Display Unit also has connections for an Abort switch. The circuit is labeled “Hold”. You must use a
470 ohm trigger resistor,
as with the panel’s Abort
circuit.

30. Other Installation Notes
The HCVR-3 panel already has a Manual Release switch.
All you have to do is pull the cover down and push the button. No wiring or programming required.
For Manual Release stations, use the
MAN. RELEASE supervised input
Note: there is programming that determines if the manual release operation will be immediate or if it will follow the normal delay. UL 864 allows a delay when the manual release switch is operated, as long as the delay is 30 seconds or less from the activation of the switch to the actuation of the releasing device(s). See UL

31. Other Installation Notes
The Manual Release circuit is wired like the Abort circuit, using a 470 ohm trigger resistor.
Here are two things to know about Manual Release:
Note on #1 – In this case the Abort button will not work, even if it is released and then pressed again.
1 – If abort is activated first, the manual release will override the abort function.
2 – If the manual release is activated first, the abort function will override the manual release*.
* Activation delay must be enabled for the manual release, otherwise the release is immediate with no time to operate the abort switch.

32. Other Installation Notes
NFPA 2010 requires a supervised disconnect switch. The purpose of this switch is to prevent unwanted discharge of the system during maintenance.
The disconnect switch must electrically open the releasing circuit.
The HCVR-DS disconnect switch* may be used for this purpose. The switch is wired into the EXTING circuit. When the switch is operated to disable the circuit, the panel will indicate a trouble condition.
--NFPA 2010, Fixed Aerosol Fire-Extinguishing Systems, 2010 Edition--
Disconnect Switch. A manually operated switch, electrically supervised and secured from unauthorized use, that prevents the automatic or manual electrical actuation of the aerosol generators during maintenance by electrically opening the releasing circuit.
To avoid unwanted discharge of an aerosol system during maintenance, a supervised disconnect switch shall be provided.
The disconnect switch shall interrupt the releasing circuit to the aerosol system.
--NFPA 72, 2013 Edition--
Releasing service fire alarm systems used for fire suppression–releasing service shall be provided with a disconnect switch to allow the system to be tested without actuating the fire suppression systems.
“Operation of a disconnect switch or a disable function shall cause a supervisory signal at the releasing service fire alarm control unit.”
{The HCVR-3 does not indicate a Supervisory signal. Only an open-circuit trouble condition is indicated. Unfortunately this does not comply with UL 864 either (note that the HCVR-3 does not indicate Supervisory at all). This solution is the best we have for now, and it does allow us to comply with the requirement to have a physical disconnecting means.}
The disconnect shall be a physical switch and not be accomplished by using software.
Software disconnects, even if activated by dedicated buttons or key switches, shall not be permitted as a method to secure a suppression system from inadvertent discharge.
*Formerly SOM-R-DS

33. General sequence of operation*:
1 - One of the cross-zones goes into alarm.
The Fire and Fire In Zone indicators will illuminate. NACs 1 & 2 will activate, as will the relays. The 1st Stage Activated indicator will illuminate and the panel buzzer will sound.
2 – The other cross-zone goes into alarm.
The Fire and (2) Fire In Zone indicators will illuminate. If the NACs had been silenced they will resound. The Release Imminent indicator will illuminate and relays will operate. The LED display will indicate the time remaining until release, counting down to 0. NAC 3 will operate in a pulsing pattern to indicate the pre-release condition. An Abort will halt the countdown at 10 seconds.
After the delay timer expires the EXTING circuit will activate. NAC 3 will change to a continuous pattern. The Extinguishant Released indicator will be illuminated.
* Operation may differ from this based on programming. There are several programmable options for the HCVR-3.

34. Operation and Programming
Operating the HCVR-3
There are basically two access levels – Level 2 and Level 3.
Technically there are 3 access levels. Access Level 1 allows you to use the Lamp Test and Manual Release buttons. You may also use remote Abort and Manual Release switches.
Level 2 allows some access to the controls and limited programming.
Level 3 allows full access to the controls and all programmable options.

35. Operation and Programming
To enable Level 2, turn the Enable Access key to the right.
The display will show “Ad”. Like this:
You will use:
The Mode button to move to the desired function;
The Select button to scroll to the desired zone;
The Enter button to select or de-select a function
The System Mode display will indicate the function that is being set.
Uh…
Got it?
Let’s try an example…

36. Operation and Programming
First, let’s look at the functions that can be performed
Test Zones (t1 / t2 / t3)
Disable Zones 1 – 3 (d1 / d2 / d3)
Disable NAC 1 (db)
Disable 1st Stage Relay (dP)
Disable 2nd Stage Relay (dA)
Disable Extract Fan Relay (dc)
Disable Manual Release (dt)
Disable EXTING Circuit (dE)
Activate Delays (Ad)
Activate Extract Fan Relay (Ac)
Test Zones - Zones in Test Mode automatically reset 3 seconds after operating. The Test Mode On and Zone Trouble/On Test/Disabled indicators illuminate when zones 1, 2, or 3 are in Test Mode.
Disable Zones – Disabling Zones does not provide fire or trouble indications on the fire control panel. The General Disablement and Zone Trouble/On
Test/Disabled indicators illuminate when zones 1, 2, or 3 are disabled.
Disable Manual Release – panel and remote manual release circuits are disabled.
Disable EXTING Circuit – disables the pre-release timer and EXTING output operation. Extinguishant output trouble conditions are ignored when the extinguishant release is disabled.
Activate Delays – enables NAC delays as set in Level 3 programming options C00 - C09.
The codes shown above are those that you will see on the System Mode display.
When a function has been set, a small dot will appear at the bottom-right corner of the display.

37. Operation and Programming
Let’s disable the EXTING circuit.
Step 1 – turn on the key
The System Mode display will show “Ad”.
Step 2 – find the code to disable the EXTING circuit.
The HCVR-3 manual says that it is “dE”.
Step 3 – Press the Mode button until the display shows dE
Step 4 – Press the Enter button. The dot on the display indicates that this function is set. The panel will indicate trouble as well.

38. Operation and Programming
While we are on the subject of disabling the EXTING circuit…
NFPA does not allow this circuit to be disabled solely by software.
The disconnect (for the releasing circuit) shall be a physical switch and not be accomplished by using software. (NFPA 72, 2013 Edition)
Software disconnects, even if activated by dedicated buttons or key switches, shall not be permitted as a method to secure a suppression system from inadvertent discharge. (NFPA 72, 2013 Edition)
References on the slide are from the 2013 edition of NFPA 72.
NFPA 2010 requires this too.
“To avoid unwanted discharge of an aerosol system during maintenance, a supervised disconnect switch shall be provided.”
“The disconnect switch shall interrupt the releasing circuit to the aerosol system.”
NFPA 2010 is the Standard for Fixed Aerosol Fire-Extinguishing Systems. These excerpts are from the 2010 Edition.
UL 864 does not require this…yet. But changes have been suggested that will add this and other requirements.

39. Operation and Programming
How about putting zone 3 in Test mode?
The code for this function is “t3”
Turn on the key and press Mode until you see “t1”.
Press the Select button until you see “t3”
Press Enter. Test mode is now active for zone 3.
To cancel a function and return the panel to normal, simply select the function and press the Enter button again so that the dot is not displayed.

40. Operation and Programming
Let’s look at the programming options. How do we enable Level 3?
Turn on the Enable Access key and slide the Write Enable switch to the right.
The display will show “U##”. The number (##) indicates the number of times that the level 3 configuration has changed.
The programming procedure is the same as setting the level 2 options.
You will use the Mode, Select and Enter buttons along with the System Mode display to configure the programmable parameters.
Let’s look at the programmable options…

41. Operation and Programming
NAC Delay Time – sets a time delay before NACs operate. Only one may be selected.
C00 = 30 seconds C05 = 5 minutes
C01 = 1 minute C06 = 6 minutes
C02 = 2 minutes C07 = 7 minutes
C03 = 3 minutes C08 = 8 minutes
C04 = 4 minutes C09 = 9 minutes
Note: delays are activated by the “Ad” option in Access Level 2.
See Appendix G of the HCVR-3 manual.
For UL 864 9th Edition compliance, this setting may not be used.

42. Operation and Programming
Coincidence detection options. Only one may be selected.
C11 – Zone 1 & Zone 2 starts the automatic release
C12 – Zone 2 & Zone 3 starts the automatic release
C13 – Zone 1 & Zone 3 starts the automatic release
C14 – Zone 1 & Zone 2 or Zone 2 & Zone 3 or Zone 1 & Zone 3 starts the automatic release.
C15 – Zone 1 & Zone 2 & Zone 3 starts the automatic release
C16 – Zone 1 or Zone 2 or Zone 3 starts the automatic release
C17 – Zone 1 starts the automatic release
C18 – Zone 2 starts the automatic release
C19 – Zone 3 starts the automatic release
Any one of these settings is permitted by UL. Choose the correct setting according to the design of your system.

43. Operation and Programming
C21 – Disable Fire Buzzer (not permitted by UL 864, must be enabled)
C22 – Disable Fire Relay (not permitted by UL864, must be enabled)
C23 – Disable Trouble Relay
C24 – Disable Ground Fault (not permitted by UL 864, must be enabled)
C25 – Pulse R0V Output
C26 – Remove 24VDC aux power on system reset
C25 causes the R0V terminal to pulse on and off. Not sure why anyone would want this…
If C27 is not set, the Extinguishant Release LED will only illuminate when the REL. PRES. SWITCH input is activated.
C27 – Indicate “Extinguishant Released” when EXTING circuit is active

44. Operation and Programming
C28 – No activation delay upon manual release
C29 – Release can be cleared by panel reset during imminent phase
C2A – Local Fire relay operates with Extinguishant Released indication
C2b – EXTING output on until panel is reset (no auto shutoff)
C2C – LOW P. SWITCH input uses N/C contacts

45. Operation and Programming
C31 – Zone 1 alarm delay enabled
C32 – Zone 2 alarm delay enabled
C33 – Zone 3 alarm delay enabled
When the “Ad” option is set and the C31 – C33 options are set, the NACs (1 and 2) will follow the delay time set in C00 – C09.
Remember, UL does not allow delayed NAC operation!
For UL-compliant installations you may not use any of the C31 – C33 options.
“Ad” option – Activate Delays, Level 2 menu

46. Operation and Programming
C41 – Zone 1 pull station alarm delay enabled
C42 – Zone 2 pull station alarm delay enabled
C43 – Zone 3 pull station alarm delay enabled
These are similar to the C31 – C33 options. And they are not permitted for UL compliance. Leave these options disabled.
C61 – Zone 1 operates through I.S. barrier
C62 – Zone 2 operates through I.S. barrier
C63 – Zone 3 operates through I.S. barrier
Not used. Leave these options disabled.

47. Operation and Programming
C71 – Zone 1 short circuit causes an alarm
C72 – Zone 2 short circuit causes an alarm
C73 – Zone 3 short circuit causes an alarm
If these options are disabled a 470 ohm trigger resistor must be used with the zone. A short-circuit will be indicated as a zone trouble.
If you find that the panel shows a trouble during alarm, check these options to be sure that they are enabled.

48. Operation and Programming
C81 – Zone 1 is non-latching
C82 – Zone 2 is non-latching
C83 – Zone 3 is non-latching
As you may have suspected, non-latching zone operation does not comply with UL 864 9th Edition requirements.
Leave these options disabled (latching).
CA1 – Zone 1 input delay (30 seconds)
CA2 – Zone 2 input delay (30 seconds)
CA3 – Zone 3 input delay (30 seconds)
Do you think that UL will permit us to delay the indication of a fire alarm?
Leave these options disabled for UL 864 9th Edition compliance.

49. Operation and Programming
These modes are accessed by pressing the Lamp Test button.
E00 – Panel can be reset immediately after discharge output has operated*
E01 – E30 – panel can be reset 1 to 30 minutes after discharge output has operated.
* Note: auto-shutoff of the EXTING circuit will supersede this setting
-00 – No delay between alarm activation and EXTING circuit operation.
-05 to -60 – Delay time (in seconds) between alarm activation and EXTING circuit operation. This is the time that will be seen on the panel display during the Release imminent phase.
Use the Mode button to set the 10s and the Select button to set the 5s.

50. Operation and Programming
060 – Sets the duration time for the EXTING circuit to 60 seconds.
065 to Sets the duration time for the EXTING circuit. 5-second intervals.
The C2b option must not be set to use EXTING duration time.
That’s all of the programmable options for the panel.
As you probably noted, many of them may not be used for UL-compliant systems. Here is a review of the options that you can use:
C11 – C19 Determine how automatic release is started (cross-zone, all-zones, single-zone)
C23 Disable trouble relay
C25 Pulse R0V output
C26 Aux power is resettable
C27 Extinguishant Released LED operation
C28 Manual Release delay
C29 Panel reset possible during imminent phase
C2A Local fire relay operation
C2b EXTING output ON until reset
C2C LOW P. SWITCH is N/C
C71 – C73 Short circuit causes alarm
E00 – E30 Panel reset delay time
-00 – -60 Delay until release
060 – 300 EXTING circuit activation time

51. Operation and Programming
After the programming is completed, be sure to move the Write Enable switch back to the OFF position (to the left).
If you forget, the panel buzzer will sound and the General Trouble LED will be illuminated.
Some Programming Tips:
Keep your eye on the dot!

52. Operation and Programming
Be sure that the EXTING circuit is disabled when making and testing your programming changes!
Remember the HCVR-DS Disable Switch?
Record the configuration update count when finished programming.
This number changes each time L3 programming is changed.

53. Testing & Troubleshooting
First step is to test the system for proper operation.
Be sure that the EXTING disconnect switch is activated. Alternately, you can disconnect the circuit at the panel and install the EOL diode to clear the open circuit trouble.
Confirm the proper operation of all inputs and outputs.
Ensure that the EXTING circuit activates as expected.
Check the operation of Abort and Manual Release switches.
Carefully follow all local and national requirements to check for proper system operation.
The EXTING circuit uses an EOL diode (not used with FireNET Xtinguish)
The NACs use a 10K EOL resistor
All other supervised circuits use a 6.8K EOL resistor

54. The diagnostic LEDs are an excellent troubleshooting tool.
Problems such as low battery, ground fault and wiring trouble are indicated.
If the Tell Tale LED is lit it means that the Manual Release was activated.
Be sure to clear this after the testing and user training is complete.
Most problems are quickly identified by using the indicators on the HCVR-3 panel.

55. Maintenance
Follow the inspection, testing and maintenance requirements of local and national authorities.
Chapter 14 of NFPA 72 (2013 Edition) provides direction on test frequency and test methods that apply to the FACP and its devices.
The releasing system inspection, testing and maintenance will be covered by other standards.
Don’t forget to keep records of all inspections, testing and maintenance.
