4 Zone Sounder Circuit Extender Kit

Provides four extra conventional sounder circuits with open and short circuit fault monitoring.
Compatible with most manufacturers’ fire alarm control panels.
Supplied on a double gang plate.
Basic connection requires four wires: 24 VDC, 0V, Sounder –Ve & Sounder +Ve.
Sounder -Ve & Sounder +Ve can be connected at the host panel or any convenient point on a sounder circuit (DO NOT SPUR). 24 VDC and 0V can be derived from the host panel or, alternatively, from an external PSU.
If connecting the FF502P to a C-TEC fire panel only three input control wires are required (Sounder -Ve is not required as our conventional panels have a common 0V rail).
Fits on standard UK 25mm flush or surface mount back boxes.

Application/operation	When the host sounder circuit is activated, the FF502P’s sounder circuits follow. If an open or short is detected on any extender circuit, the FF502P connects a 680Ω resistor across the host cir
