Check the cabling
Before connecting the Control Panel or Remote Unit electronics to the cabling, check all cabling for correct
phasing absence of shorts, etc.
It is most important that power is not applied across the data pair or reversed, as this will cause
damage to the equipment.

1. If not already fitted, mount the
supplied back box at each
Remote Unit location. Generally
at a height of 1.3m to 1.4m from
the floor, but at 900mm to 1.2m
in refuges.
2. At the rear of the Remote Unit
remove the screw to release the
bracket retaining the blue
termination block.
3. Terminate all cables at the
termination block according to
the system designer’s
specifications and the diagram
on the Remote Unit rear panel.
It is very important that each
conductor is correctly identified
before being terminated.
Incorrect connections can
damage this equipment.
4. Refit the retaining bracket over
the blue termination block and
replace the screw.
5. Connect the green and yellow
safety earth lead to the earth
terminal in the back box.
6. Fit the Remote Unit to the back
box using four screws provided.
