iConnect PIR Sensors (EL-2745/2745PI)
The EL-2745/EL-2745PI are wireless PIR sensors designed for use with Electronics Line 3000’s supervised wireless
range of receivers. The EL-2745PI sensor is designed for pet installations and provides good immunity to nuisance
alarms caused by pets weighing up to 45kg (100lbs). The EL-2745/EL-2745PI implement a feature to combat the
problem of multiple transmissions that drastically reduce the life of the batteries. After each detection, the sensor
initiates a three-minute delay during which transmissions will not be sent.
Detectors that meet the EN-50131 standard, have a three-minute delay between
transmissions.

Location of Detector
Consider the following before mounting the detector:
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.
