Object 18 – Alarm Control Object

The Alarm Control Object provides information about any alarms which are present in the HGM. It also provides mechanisms for acknowledging alarms, and for viewing and setting the Leak, Spill, and Evacuate alarm thresholds for each zone:

Network input variable nviHgmAlarmAck has a single parameter (unsigned short) which specifies which zone alarm the operator wishes to acknowledge. A value of 1-16 acknowledges the alarm for a single specified zone. A value of 0 is a global acknowledge for all zones in alarm.

Network input variable nviHgmAlmAckSw is a global alarm acknowledge of standard type SNVT_switch. It is useful for binding to an Acknowledge pushbutton on a remote alarm annunciation panel using a network output variable of type SNVT_switch. To acknowledge alarms, set nviHgmAlmAckSw to value=200, state=1. Depending on the presentation software, full-scale “value” may be “200” or “100.0”.
