Description
The ANN-80 fire annunciator is a compact, backlit device featuring an 80-character LCD screen that replicates the display of the Fire Alarm Control Panel. It delivers system status indicators for conditions such as AC Power, Alarm, Trouble, Supervisory, and Alarm Silenced. Communication between the ANN-80 and the Fire Alarm Control Panel occurs through a two-wire serial interface utilizing the ANN-BUS communication protocol. The connected devices receive power via two extra wires, supplied by either the host Fire Alarm Control Panel or a remote UL-listed, filtered power source.
