THE ALARM CUTOFF/LAMP BUTTON

Each system has an Alarm Cutoff (ACO)/Lamp Button located on the LED panel that disables the external alarm contacts and tests the LEDs.

Disabling Alarms

To disable the external alarm contacts, press and release the button marked ACO/LMP.

The ACO LED lights and the alarms are disabled for the length of time specified in the System Settings screen of the craft interface1 or through SNMP.

Testing LEDs and Resetting the ACO

As part of the LED test, the ACO is reset (the alarms are enabled). If the alarms are disabled when you test the LEDs, you must disable them again (see above) when the test is complete to return them to their previous state.
