FIREFINDER SERIES II INSTALLATION, COMMISSIONING &

OPERATION

11 Expanding the FACP with Compatible FireFinder

Boards

11.1 Ancillary Services

The FACP has been designed such that detectors and/or call points, in addition to giving an alarm

and calling the fire brigade, will close or open circuits of ancillary services by means of relays or

similar devices.

Examples of these services are:

 Actuation of fixed fire-extinguishing systems;

 Closing of windows, smoke and fire doors,

 Control of ventilating systems;

 Covering of tanks containing flammable liquids and controlling their valves to isolate the

contents from direct contact with the fire, etc.

To facilitate safe maintenance of these services an option is available that allows for the isolation

and visual indication of the disablement of ancillary services that does not affect the normal

operation of the fire alarm system.

To ensure power to the fire alarm system is not prejudiced in any way, power for the ancillary

services must be included in the calculation of the power supply and battery capacity.
