FF502P Four zone monitored sounder extender, supplied on a double gang plate. 

The FF502P provides four extra sounder circuits with open and short circuit fault monitoring. It is compatible with most fire alarm control panels and is supplied mounted on a doublegang plate which fits standard UK 25mm deep back boxes.

Basic connection requires four wires: 24V DC, 0V, Sounder –Ve & Sounder +Ve. Sounder -Ve and Sounder +Ve can be connected either at the host panel or at any convenient point on an individual sounder circuit (DO NOT SPUR).

24V DC and 0V can also be derived from the host panel or, alternatively, from an external power supply. However, the power supply to the FF502P must be capable of providing the full anticipated load on all four sounder circuits.

Please note: If connecting the FF502P to C-TEC’s CFP, MFP or FP range of fire panels only three input control wires are required (Sounder -Ve is not required as C-TEC conventional panels have a common 0V rail). If this type of connection is required link PLK3 must be fitted.
