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.
