• Auto-silence and auto-acknowledge features, with delay settable from 1 – 255 s
• Other amount of windows available upon request.
The AN112/120 series Alarm Annunciator provides ideal solution for all your alarm system management and requirement. It comes with either 12, 20 or 28 windows, and due to the use of microprocessor-based design, the alarm annunciator is highly
and industries.

Product Description
Alarm relay provides LED indication and output
contact signalling when there is alarm signal
received. The alarm relay consist of alarm input,
alarm accept, alarm reset, lamp test controlled
input and 2 relay contacts. Red LED indication
2 (LED) turned on when alarm signal is received.
