System Test
System test simulates a full alarm condition on all channels therefore the associated LED’s will flash
and the audible alarm will sound. The appropriate pushbuttons, Ack, Mute & Reset will need to be
pressed, depending on the selected alarm sequence, to return the alarms to their normal off state.
Disable Horn On System Test Option “DHT” (Model Suffix Code M1)
As an option it is possible to provide the UC625 Unit so that the horn outputs are disabled during
system test if required. Option DHT must be specified at time of order placement if this feature is
required.
LED Indication
The Series UC625 Alarm Annunciator is supplied with 8mm super bright LED’s mounted in the left
hand corner of the associated window. The LED is normally supplied in red but other colours are
available on request.
