General Purpose Output (GPO) Configuration
The Alarm Terminal Block located on the unit rear panel (for details, see unit Rear Panel

(GPO) relay contacts as office alarms or external controls.
The GPO relay contact can be set to one of the following:
 Office alarm indications (Critical/Major)
 External control such as sprinkler, lights, air-conditioning etc.
The default setting is office alarm, which can be connected to external alarm device(s).
Office Alarm Control
A single Normally Open (NO) GPO relay is provided in the ML system for Office Alarm
indication. A sound emitting device can be connected to the Office Alarm relay to provide
audible alarm functionality.
When the unit is configured for Office Alarms and connected to an external audible device
then a Major or Critical alarm raised on the ML device will also activate the Audible office
alarm.
Office Alarm will Close due to:
 Unit initialization
 Critical or Major failure
NOTE: Alarms suppressed due to Partial alarm LED configuration are not reported via GPO.
