Fire-Lite ANN-RLY 10 Relay Board Mount

The ANN-RLY relay module provides 10 programmable Form-C relays when used with a compatible FACP (Fire Alarm Control Panel). The ANN-RLY module may be mounted inside the FACP main circuit board chassis or in the battery area of the enclosure using optional mounting bracket P/N: ANN-MBRLY. Reference Installation Instructions document #53033.
The ANN-RLY and the FACP communicate over a two-wire serial interface employing the ANN-Bus communication format. An additional two wires are used for 24-volt DC power. A single four-conductor unshielded cable may be used for both power and data communications.
Up to eight ANN-Bus devices may be connected to the ANN-Bus of each FACP.
