The FW2811 input module monitors a single contact. 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 one address on SLC or Data Communication Link (DCL) of the fire alarm control panel.

The FW2811 is a UL listed device according to UL864 and ULC-S527 and the type of the input contact is configurable for 4 types:

Alarm

Supervisory

Trouble

Monitor or feedback
