EL-2645PI
The EL-2645PI is a wireless PIR sensor designed for use with Electronics Line 3000’s supervised wireless range of
receivers. The detector is designed for pet installations and provides good immunity to nuisance alarms caused by
pets weighing up to 100lbs (45kg). The EL-2645PI implements a feature to combat the problem of multiple
transmissions that drastically reduce the life of the batteries. After each detection, the EL-2645PI initiates a three-
minute delay during which transmissions will not be sent.
Location of Detector
Consider the following before mounting the
detector:
• Select a location from which the
pattern of the sensor is most likely to
be crossed by a burglar, should there
be a break in.
• Do not place bulky objects in front of the
sensor.
• Avoid a location which comes in direct
contact with radiators, heating/cooling
ducts and air conditioners.
Pet Immunity Guidelines
It is expected that the detector will eliminate false
alarms caused by animals up to 100lbs/45kg,
several small rodents and random flying birds.
Note: 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.
For maximum pet immunity the following
guidelines are recommended:
• Mount the center of the detector at a
height of 6.5’ (2m) with the PCB
vertical setting at -4.
• Set the pulse counter to 2.
• Do not aim the detector at stairways that can be climbed by an animal.
• Avoid a location where an animal can come within 6’ (1.8m) of the detector by climbing on furniture, boxes
or other objects.
Installation
1. Open the housing by removing the front cover. To do so, insert a screwdriver in the release slot (located at
the bottom of the detector between the front and back cover). Turn the screwdriver 90º to release the cover.
2. Remove the PCB by turning counter-clockwise and removing the "Easy Lock".
Note: Do not touch the face of the PYRO sensor.
3. Apply battery power by removing the insulator that separates the battery from the contacts on the battery holder.
4. Place the Mode jumper over pins 2 & 3 (Radio Mode); the LED flashes.
Note: Install the Mode jumper only after applying battery power. Due to the occurrence of voltage delay in lithium
batteries that have been in storage, the batteries may initially appear to be dead. In this case, leave the unit in Radio
mode for a few minutes until the battery voltage level is stabilized.
5. Set the receiver to Registration mode and wait for the receiver to indicate that the transmitter has been
registered successfully. Write the number of the zone and the transmitter number (if applicable) on the
sticker provided. Affix the sticker inside the front cover for future reference.
6. Remove the jumper and place it over one pin for storage - see Mode Jumper Safeguard.
7. Choose an appropriate mounting height (6.5’/2m recommended for maximum pet immunity) and test the
transmitter from the exact mounting position before permanently mounting the unit.
8. Knock out the mounting holes and attach the base to the wall.
9. Mount the PCB at the required vertical adjustment and replace the PCB screw.
10. Replace the front cover.
Note: The Vertical adjustment scale relates to the
top edge of the adjacent plastic stud (A)
