PIR Detectors (EL-2645/EL-2645PI)
The EL-2645 and EL-2645PI are Wireless Motion PIR Detector designed for use with Electronics
Line supervised wireless range of receivers. All these detectors implement a feature to combat the
problem of multiple transmissions, which drastically reduce the life of the batteries. After each
transmission, there is a four-minute delay during which further transmissions will not be sent.
When batteries need replacing, the detector sends a low battery indication to the Control System.
The EL-2645PI is designed for pet installations and provides good immunity to nuisance alarms
caused by pets and animals.
Detectors that meet the EN-50131 standard, have a three-minute delay between
transmissions.

Considerations before Installation
•
Select a location from which the pattern of the detector is most likely to be crossed by
a burglar, should there be a break in.
•
Do not place bulky objects in front of the detector.
•
Avoid a location that comes in direct contact with radiators, heating/cooling ducts or
air conditioners.
•
Do not place the detector in front of windows subject to direct sunlight or drafts.
Pet Immunity Guidelines (EL-2645PI)
It is expected that the EL-2645PI will eliminate false alarms caused by:
•
Animals up to 36kg/80lbs
•
Several small rodents
•
Random flying birds.
The weight of the animal should only be used as a guide; other factors such as the length
and color of fur also affect the level of immunity.
