80-Character Serial LCD Annunciator 315-080
Fire Projects recommend the 315-080 annunciator is a compact, backlit, 80-character LCD fire annunciator that mimics the Fire Alarm Control Panel (FACP) display. It provides system status indicators for AC Power, Alarm, Trouble, Supervisory, and Alarm Silenced conditions. The 315-080 and the FACP communicate over a two-wire serial interface employing the Repeater-Bus communication format. Connected devices are powered, via two additional wires, by either the host FACP or a remote UL-listed, filtered power supply.
