8.2.4 Alarm Relay Output
The Alarm relay is a normally open earth free relay contact, provided as an independent and simple method
for triggering an external alarm. The alarm relay is deactivated upon acknowledgment of an alarm, either
internally on the display unit, or by an externally provided ACK sentence. If the Transponder power is lost,
and the Alarm relay has power, the alarm will be triggered. In this case, the only way to deactivate the Alarm
is to power the Transponder unit or disconnect the power source of the Alarm relay.
