5. Installation
• Ensure the mains supply is switched off and the circuit supply fuses
are removed or the circuit breaker turned off.
• This product is designed to be mounted on walls or under eaves
(See diagram “C”). The sensor can be rotated through 180 degrees
to direct detection where required.
• An isolating switch should be installed to enable the power to be switched ON
and OFF for maintenance purposes and to activate the manual/auto
override function.
• Unscrew the wiring box fixing (See diagram “D”). This screw is captive,
do not fully remove.
• Detach the wiring box by gently pulling it away from the PIR sensor body.
• Mark the position of the fitting holes using the wall plate as a template. Drill
out the mounting holes taking care to avoid any joists, electrical cables or
water/gas pipes that may be hidden beneath the surface. Insert the rawl plugs
into the holes.
• Pass the cables through the cable entry points on the wiring box, ensuring the
grommet(s) is used to maintain the IP rating of the PIR sensor.
• Fix the wall plate to the wall using the correct screws for the rawl plugs
installed (See diagram “E”).
• This unit features an installation aid. Simply hang the PIR sensor onto the
wall plate by use of the clip arrangement on the wall plate (See diagram “F”).
This allows you to use your hands to hold the screwdriver, and install the
incoming cables with ease.
• Terminate the cables into the terminal block ensuring correct polarity is
observed and that all bare conductors are sleeved (See section 6.
Connection Diagram).
• Ensure the connections are secure, and that the terminal blocks are attached
to the mounting posts in the PIR sensor body.
• Un-hook the sensor unit and re-attach to the wiring box, ensuring none
of the wires are trapped.
• Align the PIR sensor centrally over the wiring box, and attach the top edge of
