HGM Alarm Acknowledge Options

Two alarm acknowledge options are supported—Auto Acknowledge and Network Acknowledge.

In the Auto Acknowledge mode, the HGM will clear its alarm outputs the next time the alarmed zone is sampled and its PPM has dropped below the alarm thresholds. No intervention from the LonWorks network is necessary.

In the Network Acknowledge mode, the HGM will never clear its alarm outputs until LonWorks has acknowledged the alarms using network variables nviHgmAlmAck or nviHgmAlmAckSw (discussed below). Once LonWorks has acknowledged the alarms, the HGM will clear its alarm outputs the next time the alarmed zone is sampled and its PPM has dropped below the alarm thresholds.

Dipswitch A1 on the adapter selects which alarm acknowledge option is used:

A1 On = Auto Acknowledge

A1 Off = Network Acknowledge

If dipswitch A1 is changed while the adapter is powered up, the adapter must be reset by pressing the CPU RST button below dipswitch A before the change will take effect.
