SERIES AN2
INDICATING ALARM ANNUNCIATOR
Up to 8 Inputs, Integral Power Supply
Alarm Modules
Annunciators/
The Series AN2 Indicating Alarm Annunciator provides visible and audible alarms
for up to eight inputs. Audible alarm conditions can be acknowledged, reset, or silenced
either via the front panel push-buttons or the rear terminal block. The annunciator also
has two SPDT relay outputs that can be used to initiate external alarms, buzzers, or
paging devices.
