Ref: XL-APIRAn additional wireless PIR to add to your XL alarm system. This unique battery powered wireless PIR can be added to any of our XL alarm systems working as an audible, alert or a full alarm system, and has an impressive working range of 80 metres allowing you to protect outdoor areas, garages, sheds & other outbuildings.
Powered by a PP3 9volt battery that will operate for about 12 months in most applications.
It has a detection range of 13 meters, and is supplied with a fully adjustable swivel mounting bracket.
Kit Includes:PIR
Mounting Bracket.
PP3 Battery.

Your motion detectors are rainproof however; we strongly recommend using our specially designed rubber hoods for full protection from harsh rain, wind and sun.
Mounting the PIR Sensor:The key to successful operation of any PIR sensor is choosing the correct location. A sensor mounted in a unsuitable location has the potential to cause false triggers and reduce performance. The main rules that should be followed are:
1) Mount the PIR into a corner of a room.
2) Avoid heat spots from bright lamps suddenly turning on or off.
3) Do not install immediately above a radiator.
4) Do not install in a glass roof conservatory.
How PIR's Work (passive infrared detector):All PIR sensors detect changes in infra-red radiation, in the form of heat emitted by a number of bodies including people, cars and to a lesser extent, dogs or other small animals. The bigger the body, the more infra-red radiation isemitted and the easier it is for a PIR sensor to detect.
The field of view is the area in which changes in infra-red radiation can be detected. The field of view can alter with changes in temperature and the size of the heat source.
The construction of the PIR and Fresnel Lens divide the field of view into a number of zones both vertically and horizontally.
Multi Element Fresnel Lens:The lens focuses the infr-red radiation given out by a hear source on to the Pyroelectric sensor. The different elements or facets of the lens divide the incoming infra-red radiation into vertical and horizontal zones.
Pyroelectric Passive Infra-Red Sensor:The dual element Pyroelectric sensor receives the incoming infra-red radiation from various zones. The two elements of the sensor receive varying amounts of infra-red radiation and this difference is amplified, turning into a signal via the IC. This signal activates the microcontroller. The sensor detects infra-red radiation in the wave length from 8 - 14 metres.
Intergrated Circuit Control Chip (IC):This is a customised chip which controls the various modes of operation, timing functions and the processing of the signal from the sensor to drive wireless alarm signals to alarm panel.
