CPU or Network Control Annunciator
Loop Control Modules
Digital Voice Controller
Microphone
Telephone Handset
Mic/Phone wells
Special chassis
Digital Amplifiers
Power Supply
Batteries
B, C or D-size Cabinet
Special Cabinet Doors

14. Microphone, Fire Fighter Telephone
A microphone and Fire Fighter’s Telephone are housed in a cage assembly that mounts to the right of the CPU/DVC. These devices connect to the Digital Voice Controller.
An alternate assembly provides a housing for a single microphone alone.

19. Digital Audio Amplifiers
The DVC system can employ Three versions of audio amplifiers
DAA (50 Watt, 25 Volt)
DAA (50 Watt, 70 Volt)
DAA (75 Watt, 25 Volt)
These amplifiers are self-contained assemblies that consume one row in the cabinet.
Each amplifier contains a chassis, power supply, battery charger (Except DAA 7525), battery rack, and on-board speaker circuits (4 Class B or two Class A). The four circuit share 50 the amplifier’s 50 watts and are controlled by the DVC.

21. Distributed Amplification
Distributing the amplifiers throughout the protected premises minimizes high-level signal loss and increase the survivability of the overall system.
Backup amplifiers are on a one-to-Many basis.
Amplifiers can be installed in successive rows within the cabinet provided background music is not employed.

DAA
One DAA Series Amplifier can be installed in one A or B CAB
Two DAA Series Amplifiers can be installed in one C or D CAB
A CHS-BH1 Battery Holder is required for Batteries in Row 1. Two 12 AH batteries are supported
Batteries can be installed in the battery space of the cabinet for the lower DAA or the battery holder can be used for this amplifier also.
Issue as of now is heat dissipation and crosstalk.

23. An LCM-320/LEM assembly mounted under CPU position
Audio Configurations
In a Digital Voice Command system, either a CPU or a NCA-2 may be housed above the voice controller. For DVC usage in a network system, the NCA is required.
Loop Control Modules may be installed underneath the CPU or in a dedicated row within the cabinet.
The Power Supply and batteries are mounted in the standard position inside the cabinet or battery enclosure.

24. Chassis, Dress Panels & Plates
Often one of the most overlooked components of a fire alarm system is the mounting hardware and dress plates necessary to complete the system.
Chassis are used to mount components inside the cabinet.
Blank Module Plates cover unused module positions within the cabinet.
Trim Rings cover gaps in the wall around the control panel or remote device.
The CA-1 is a single row dress plate
Mounting well for microphone and telephone.
Half-Chassis for NFS or NCA-2.
The tricky part is sometimes there are optional mounting solutions for the same component depending upon where in the cabinet it is to be installed or what other equipment will be located inside the cabinet. Most of the hardware has multiple uses as well. If we had a Price List with pictures and rules for use, however unfeasible that may be, it might not be too difficult to determine your hardware requirements. But that’s not the case. You just gotta learn all this stuff.

25. Chassis, Dress Panels & Plates
The CHS-4 is a quite versatile chassis that can be used to mount a variety of modules – loop cards, network cards, relay cards, etc.
You have the ability to mount cards on top of cards inside the cabinet. The disadvantage to this approach is access to the modules becomes more difficult as they are stacked.
The ADP-4 Dress Panel provides for the mounting of annunciators over the top of other modules mounted insider the cabinet.
