DET-REXT-PIR30 Perimeter Radio PIR
Installation Instructions
Introduction
The DET-REXT-PIR30 is an outside radio
PIR (Passive Infra-Red) detector for
perimeter protection. The unit uses two
independent detectors, both of which
must trigger to cause the detector to
signal an alarm. The detector delivers
precise, reliable presence detection.
The unit is battery-powered, has a
range of up to 30 metres and can be
aligned without any change to external
appearance.

qualified service personnel.
Installing the unit
Step 1: Choose location
The PIR detects changes in heat and
movement; therefore items such as
trees, shrubs, ponds, boiler flues,
air conditioning units and animals
should be considered. The sensor is
more sensitive to movement across
the beams than to movement directly
towards or away from the beams.
The ideal mounting height is 3m. At
greater heights, the target may need
to move a greater distance before an
alarm is generated.
For pet tolerance, a mounting height
of 1.5m is recommended, the creep
mirror must be removed from around
the PIR sensor and the lower half of
the lens must be masked (Figure 2).
Coverage
The following provide examples of
coverage, depending on mounting
height, tilt and lens masking. A marker
on the side of the detector assembly
gives the degrees of tilt. The examples
assume default programming settings.
0° tilt, no lens masking
Figure 1. Optimum coverage
Note: The range in Figure 1 reduces to
20m by masking the upper section of
the lens. Masking the upper section
and programming for minimum range
reduces the range to 6m.
Note: If the detector is mounted at 6m,
