These instructions should be read in conjunction with your System Installation
and Operating Instructions and be retained for future reference.

Introduction

The LuxHome PIR Detector is designed for use with LuxHome wire free Intruder Alarm
Systems operating on 433MHz only.

PIR Detectors are designed to detect movement in a protected area by detecting
changes in infrared radiation levels caused, for example, when a person moves within
or across the devices field of vision. If movement is detected an alarm signal will be
triggered (if the system and alarm zone is armed).

Note: PIR Detectors will also detect animals, so ensure that pets are not in areas fitted
with PIR Detectors when the system is armed.

Any number of PIR Detectors can be used with your system providing they are all
coded with the system house code, and are mounted within effective radio range.

The PIR Detector is powered by a PP3 alkaline battery. Under normal operating
conditions this will provide an expected life up to one year. When the battery level
becomes low the PIR Detector will flash a red LED behind the lens. When this occurs
the battery should be replaced as soon as possible.

Choosing a Position for the PIR Detector

The recommended position
for a PIR Detector is in the
corner of a room mounted at
a height of between 2 and

2.5m. At this height, the PIR
Detector will have a maximum
range of up to 12m with a field
of view of 110°.

The position of the PCB inside the PIR can be set to 5 different positions to adjust
the range of the PIR Detector. Setting the PCB in position 3 will reduce the range
to 9m approximately, with position 1 providing a range of 6m approximately. The
recommended position setting for the PCB is in position 5.

Note: The range as indicated above refers to the linear distance in front of the PIR
Detector.

When deciding upon the mounting position for the PIR Detector the following points
should be considered to ensure trouble free operation:

1. Do not position the PIR Detector facing a window or where it is exposed to or
facing direct sunlight. PIR Detectors are not suitable for use in conservatories or for
external use.

2. Do not position the PIR Detector where it is exposed to ventilation facilities.

3. Do not position the PIR Detector directly above a heat source (e.g. fire, radiator,
boiler, etc).

4. Where possible, mount the PIR Detector in the corner of the room so that the
logical path of an intruder would cut across the fan detection pattern. PIR Detectors
respond more effectively to movement across the device than to movement directly
towards it.

5. Do not locate the PIR Detector in a position where it is subject to excessive
vibration.

6. Ensure that the position selected for the PIR Detector is within effective range of the
System.

Note: When the system is armed, pets should not be allowed to go into an area
protected by a PIR Detector as their movement will trigger the PIR and generate
an alarm.
