4. Anatomy
Brains – decision making control panel
Eyes/ears – Sensors and detectors
Central nervous system – cable network
Cardiovascular System – Power supplies
Muscles – Power switching panels (MCCs)
Minimise single points of failure
Protect critical functions
Provide early warning and contingency planning
Defined failure modes

5. Controls:
Should be Application Specific – fire alarm systems are not always appropriate as life safety control systems
Should be designed with resilience, backup and reliability
Not BMS, BAS or HVAC/process control systems
Open/Closed Protocol?
Only operate on first activation (subsequent signals are locked out)
Key enabled Firefighters override

6. Decision making system
OPV Panel
Controls the whole system
Makes decisions based on a programmed cause and effect
Displays the status of the system
Allows the system to be overridden
prEN

7. Expandable modular system to suit the needs of the project
230Vac Supply
Expandable modular system to suit the needs of the project

8. OPV Control System
Bespoke/unique design for smoke control - the system design is tailored specifically to this application
 Configurable failsafe operation of the system – continues to operate in its last known state on loss of comms
Configurable failsafe operation of individual vents and dampers, should the control panel, or the network connection from the panel, fail.
Watchdog timers in all nodes (including sensors and control panels), to detect malfunctions or loss of data.
Error detection and correction on all data links.
Programmable CAE, with full boolean logic, allows for complex control algorithms and interactions, far more so than a fire alarm system.

9. OPV Control System
Allows devices within a zone to be in different states, according to device type and CAE.
Allows for active closed as well as active open states (fire alarm systems typically only have active and standby states)
8 level priority system provides comprehensive prioritization of control
Multiple thresholds per sensor allows various control states according to circumstances.
Provides non-fire operation of vents and dampers, for day-to-day ventilation and air control.

10. Sensors and detectors
Any Apollo addressable device can sit on the network:
Smoke Detectors
Heat Detectors
Manual Call Points
Override Switches
I/O devices - allow switching of up to 3 24Vdc or 230Vac items and 3 inputs
Pressure Sensors
Temperature Sensors

11. Cable Network
Comms and power networks must be protected. Should be installed with metal clips to maintain installation in a fire.
Fire rated cabling to Category 3 of BS 8519 for Life Safety Systems.
Tested under fire conditions for:
Heat
Water jet
Impact
3 Phase Power Cables should be classed as F120
Comms/230Vac/24Vdc Cables should be PH120 +

12. Power Supplies
BS 8519
Primary and Secondary sources
Automatic Transfer Switch (ATS)
Diverse Routes
Fire rated enclosures
Battery back up Panels

13. Power Switching Panels – Motor Control Panels
Used for switching high powered 3 phase fans
No specific standard on construction

14. Phase failure relays
Battery back up circuit protection
Primary and standby supplies
Primary and standby Inverters
Current monitoring of fans
Tri-rated cabling
Fault Detection
Form 2 as standard

15. External Weather protected panel
GRP Enclosure
Drip protection overhang
Not IP rated

16. Form 4 – fully compartmented panel
Each section can be isolated independently
Very high performance standard
Client specification driven – not a standard requirement
Very high cost

21. Testing and maintenance
Smoke control is a life safety system, covered by the RRO. Testing and maintenance is covered by BS 9999 Annex V
Regular testing – weekly
Three monthly full test
Annual inspection and maintenance by a competent person
BS 9991
BS 9999
SCA Guide BS
Documentation

22. Service
“A tailored maintenance regime to ensure optimum product/system performance while ensuring legislative obligations are met”
Programmed preventative maintenance
Design implications for accessibility
Non-routine maintenance/plant replacement
Continued certified performance
