Both sensors must trigger to cause the detector to signal an
alarm. The Detector uses quad PIR technology to deliver precise,
reliable presence detection.

The integral dual-axis tilt sensor allows 180° of pan and 90° of
tilt. This increases the speed of the outdoor installation and
provides incredibly accurate aiming of the detection pattern.

The electronics module is acrylic coated for additional
component stability. It is encased in a vandal-resistant, high-
impact, UV stabilized plastic housing with an opaque
polyethylene front cover ensuring that the sensor is impervious
to and unaffected by weather conditions.

Quick installation
1. Mount and connect the detector following the instructions
given later in this sheet.
2.
The detection LED (blue) flashes three times.
3. Wait approximately 2 to 3 minutes to allow the detector to
settle.
4. Press the programming button once to activate walk test
mode.
The detection LED is now enabled for five minutes.
Note:
The front cover must be fitted when walk testing.
The default settings are:
Range: 30 meters / 98 feet
Pulse count: 1
Mounting the unit
During installation, protect the electronics against water, as
trapped moisture can affect or damage the unit.
trapped moisture can affect or damage the unit.
To mount the detector:
1. Drill the wall to accept the two fixing screws and
the tamper cup (if used). See Figures 1 and 3.
A hole-drilling template is provided.
Notes
Leave a minimum 10 cm (4 inches) clearance above
the top of the detector housing to allow the cover and
the detector to be positioned correctly.

We recommend using the tamper cup on uneven wall
surfaces.

The recommended optimum mounting height for the
detector is 3 m. Whilst it is possible to mount the unit
higher, this will give a reduced detection range and

2. Remove the cover assembly by loosening the locking
screw.
Squeeze the sides of the front cover to release the internal
catches. The cover hinges from the top and lifts out of the
location slot. See Figure 2.

3. Screw the unit to the wall ensuring that the tamper pin is
correctly located and that the tamper microswitch is
closed.

fit and can be removed by carefully pulling it from the pin.
See Figure 1.
4. When the detector is aligned, connected, and
programmed to suit the installation:
a. Fit the cover to the detector base.
b. Lightly screw the locking screw using a star screwdriver.
c. Put the top of the locking tool into the small notch on
each side of the cover, and then apply slight pressure
until the cover locks into the base, as shown in
Figure 17.
until the cover locks into the base, as shown in
Figure 17.
d. Tighten the locking screw.
Fitting the Batteries
Multibeam alignment and masking
The multifunction lens fitted to the detector produces
seven long-range beams and seven medium- to short-range
curtain PIR beams. The PIR circuitry detects changes in heat
and movement in the beam pattern; therefore items such as
trees, shrubs, ponds, boiler flues, and animals should be
considered when positioning the detector.

Battery
Only use battery type 3V Lithium CR123 (x 2 provided) This will
provide 3 years operation under normal conditions.
For extended battery life a 3rd battery can be fitted into the rear
of the TX board, See Fig 5.
Observe correct polarity when fitting.
