In addition to the full alarm capability each power failure alarm channel is also equipped with a Signal
Duplicating Relay to allow notification of power failure to 3
rd
party devices.
A volt-free contact is provided per supply input, which will change to abnormal on alarm and remain in
the abnormal state until power is restored.
The output can be changed to normally open or normally closed as required.
Please note the Signal duplicating contacts are not affected by the System Test pushbutton and act as
faithful slaves of the Signal Input.
Serviceability
All servicing is carried out from the front of the unit having first removed the legend plate.
The alarm boards are universal and thus fully interchangeable as required.
No Special Service Tools Required
A screwdriver is the only tool required to remove the legend plate to access the alarm and power
board, in order to replace or remove the circuit board to make adjustments to the DIL switches.
