4 Zone Sounder Circuit Extender Kit Part No. FF502P

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.

Enquiry Form

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 circuit to indicate a fault on the host sounder zone.
