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.
. 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.
