4.6 Installing Self Contained Power Supply
This unit will mount directly below the Detector and has been designed to allow ease of installation and
maintenance. To mount the Self Contained Power Supply proceed as follows:
(1) Remove the Self Contained Power Supply from its carton and carry out a visual
inspection of the unit to ensure that no damage has occurred during transit.
(2) Remove the screw located in the recess of the lid.
(3) Position the inner metal work of the Self Contained Power Supply directly beneath the
Detector. Ensuring that the two posts on the Self Contained Power Supply are directly
beneath the Detector. Check that the position of the Self Contained Power Supply does
not restrict access to the screws on the bottom of the Detector. The Self Contained
Power Supply should fit between these two screws in order to allow the Detector lid to be
secured and removed.
(4) Position the Self Contained Power Supply so that the two posts are just touching the
Detector. This ensures that the Self Contained Power Supply will be mounted the correct
distance from the Detector.
(5) Mark and drill the wall, at this point do not secure the Self Contained Power Supply in
position.
(6) Remove the relevant conduit knock-outs from the Self Contained Power Supply and
Detector to allow routing of the interconnecting cables.
(7) Secure the Self Contained Power Supply to the wall using the previously drilled holes and
the appropriate hardware.
(8) Remove the internal power supply from its fixing and connect the incoming mains
interconnecting cable to the Live, Neutral and Earth terminals indicated on the terminal
block. Secure the power supply in position.
(9) To connect the internal power supply refer to Figure 4.5a, ensure the earth connector is
connected to the earth connection on the Detector.
(10) Do not replace and secure the lid until the unit is powered up.
