AA-2 Dual Input Alarm Annunciator

The AA is a range of 1, 2, 3 and 4 channel alarm annunciators containing a built in sounder, mute switch and alarm relay.

The units provide local audible and visual alarm indications and an alarm relay for remote indication. To reduce unwanted alarms the unit has an adjustable input time delay. Once an input has alarmed  the condition is latched until the mute switch is pressed to accept the current alarms. The units are mounted on a single gang front plate for easy installation.
