1.8.7.3 ANN-80 Remote Fire Annunciator
The ANN-80 Annunciator is a compact, 80 character, backlit LCD remote fire
annunciator. It mimics the display on the control panel and will annunciate device
type, point alarm, trouble or supervisory condition, zone assignment plus any
custom alpha labels programmed into the FACP. The annunciator also provides
system status LEDs to display AC Power, Alarm, Trouble, Supervisory and Alarm
Silenced conditions. Additionally, the annunciator is capable of remotely
performing critical system functions such as Acknowledge, Silence, Reset and Drill.
Communication between the ANN-80 and FACP is accomplished over a two wire
RS-485 serial interface employing the ANN-BUS communication format. The
devices are powered, via two additional wires, from either the host FACP or remote
UL-listed, filtered, power supply.
The function buttons, keyswitch and piezo sounder may be individually enabled and
disabled through the FACP software. Refer to "ANN-80 Options" on page 130 for
a description of this feature and programming information.
Note that if the keyswitch is enabled and remains in the unlocked position for more
than two minutes without any buttons being pressed on the annunciator, a trouble
indication will be annunciated.
