2 Installing, commissioning and testing
step 1mounting the head
Screw the head backing plate to the wall - always try to use as sturdy a location as possible, such as brick
or major structural steels (avoid mounting to outer metal cladding etc). Avoid mounting the head where direct
sunlight can shine directly into the ‘eyes’ of the beam (care should be taken when mounting in glass atriums).
Ambient sunlight will not affect the beam.
Also available - unistrut adapter plate
Use this accessory for easy mounting to unistrut fabrication. Holes are pre-
drilled to the correct pitch of the head and conveniently positioned for use
with unistrut.
2 knock-outs are provided
on both sides. Take care when
using drills not to damage the circuit
board. Only punch out with head
open and disconected from power
Wire into system as required
(see generic wiring diagram on
the following page). Ensure that
all wiring is below the level of
the front edge of the box.
Wire to low level controller using
bottom colour coded terminals.
Screw in through holes provided
outside of the rubber seal.
Connect the head to
the base plate by first
plugging in the connector.
Do not force in, white
wires should be
uppermost. Should you
forget to connect this
the controller screen
will read ERROR.
To avoid damaging the detector head never dangle the
front cover assembly from the ribbon cable.
Screw the head screws
down with the 3mm allen
key provided.
Your wiring should be
flush and not flattened by
tightening down screws.
step 2mounting the controller
Important mount the controller at eye level and ensure easy access.
Screw in through holes provided outside of the
rubber seal.
Wire to head using colour coded terminals.
If this connection is not made ERROR will appear
on the controller, this connection can be checked
by reading the resistance across the black and
grey terminals, they will read 110 ohm if OK or
220 ohm if not connected properly.

IMPORTANT ensure the
connector is this way up.
