Install a AMU-912
Initialize and Power Up the AMU-912
After power-up has occurred, all LEDs cycle in upward/downward pairs and then go off. The PWR LED remains on.
ACO P
USHBUTTON
The ACO Reset pushbutton is also used to invoke a front panel LED test. To perform an LED test, press and hold
the ACO pushbutton for five seconds, any active audible alarm relays are deactivated. This causes all LEDs to go
on for 1 second, and then return to their previous state. If a new alarmed event is detected, the new alarm causes
the audible relay for that alarm type to be reactivated. When all alarm conditions are cleared for the alarm types
that have been silenced, the ACO LED goes off.
