FireWatcher 831 Relay Module

FW831 Relay Module

The relay module FW831 is a UL / ULC listed product according to UL864 and ULC-S527 for fire protective signaling systems for indoor use.

FW831 provides two control relay outputs which will be activated simultaneously. When the outputs are activated, the device LED will indicate the event condition by fast blinking. Supports both normally closed and normally open output contact configurations.

FW851 Isolation Module

The FW851 isolator module isolates the short point on the signaling line circuit (SLC). The internal relay will be triggered to cut down the line power where the short trouble is detected.

The device LED will indicate the trouble condition by yellow steady on. A return to normal condition will cause the internal relay to normal position to restore the line power and the device LED indicator will return to the idle condition.
