Once the liquid reaches the high level (determined by the position of the float switch) the buzzer and LED warning light in the alarm are triggered (any external beacon or sounder will also activate).

The internal buzzer can be muted in order to stop the noise from the panel causing a disturbance, however, the LED will remain lit until the alarm has cleared.

If an external sounder is connected this will also be muted, however, an external beacon (if connected) will remain lit until the alarm fault is cleared. The alarm panel resets once the fluid level drops.

The grey ABS plastic enclosure measures 280mm x 270mm x 130mm and features pre-drilled entry points for mains power and the float switch. The board accepts a 230v AC mains input and supplies power to charge the 12v battery back-up.

Auxiliary 12v terminals allow addition of two external inputs, including beacons or remote sounders. The alarm also features four inputs for optional float switches, probes or pressure switches (no float is included).
