MountIng LocatIon
The Ness LUX hardwired PIR is designed for indoor
use only and can be installed in wall or corner
mount locations.
LUX is designed to be wall or corner mounted at
the optimal height of 2.1m~2.3m.
The optional Ness Quantum bracket allows LUX
to be ceiling mounting with a wide range of tilt and
swivel adjustment.
Always ensure the detector has a clear line of sight
in the area to be protected as infra-red energy does
not pass through solid objects, (including glass).
Mount the detector in a location where an intruder
is most likely to walk across the coverage pattern.
Corner mounting usually gives the best detection
coverage.
As with all PIR detectors, it is advisable to choose
mounting positions which avoid direct sunlight,
heating or cooling sources and avoid areas of
high humidity which may cause condensation
on the lens.
InstaLLatIon
1 Remove the lock screw at the bottom of the
LUX assembly (if fitted) then using a small flat
bladed screwdriver release the two front cover
tabs and remove the front cover, bottom first.
2 Release the PIR capsule from the back housing
by squeezing the two locking tabs on either side
of the capsule. Remove the capsule to keep it
safe while you install the back housing.
3 Drill out a cable entry hole at the top of the LUX
back housing. The cable entry hole hole should
be small enough for a tight cable fit to prevent
insects entering the sensor.
The housing has cable channel to allow
mounting on hard surfaces with cable entry top
or bottom.
4 Install the LUX back housing to the wall using
four screws appropriate for the surface.
At this stage any oversized cable entry or
mounting holes should be sealed with silicone
to prevent the entry of dirt and insects.
5 Insert the PIR capsule into the back housing and
push gently until the two locking tabs click into
place.
6 Connect your power, alarm and other wiring as
required.
7 Set the dipswitches as required.
8 Replace the front cover and walk test the PIR.
Fit the bottom locking screw once walk testing
is complete.

The Ness LUX hardwired PIR is designed for indoor
use and can be wall or corner mounted at the
recommended height of 2.1m~2.3m.
LUX can be mounting at higher or lower heights at
the installer’s discretion when using the optional
Quantum Swivel bracket which provides tilt and
swivel adjustment to cater for the shape or size
of the room.
If LUX is direct mounted without a bracket, the
installer’s choice of mounting height and position
will entirely determine the coverage.
