The FW812 dual input module supports two Class B input circuits, each of which is able to monitor a dry contact device. The input line is monitored for open line faults and ground faults, and the contact must thus be wired with an end-of-line resistor.

It is an intelligent addressable module and takes two addresses on the Signaling Line Circuit (SLC) or Data Communication Link (DCL) of the fire alarm control panel. Two LED indicators are employed to indicate each input circuit’s condition. The FW812 is a UL listed device according to UL864 and ULC-S527 for Fire Protective Signaling Systems for indoor use. The type of the input contact is configurable.
