* It is not recommended to mount the unit less 
than 40cm away from the path of entry 
protected by the detector. 

The EL-2650XL is a wireless PIR sensor that is able to distinguish between permitted and non-permitted motion. This allows the occupants free movement 
within the premises while detecting intrusion via doors or windows. The sensor implements a feature to combat the problem of multiple transmissions, which 
drastically reduce the life of the batteries. After a transmission is made, the EL-2650XL initiates a delay of approximately three minutes during which 
transmissions will not be sent. The sensor operates in two selectable modes: Curtain and Directional. 

Location of Detector 

Consider the following before mounting the sensor: 

 

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. 

 

Avoid a location that comes in direct contact with radiators, heating/cooling ducts or air 
conditioners.

 

 

 

Do not place bulky objects in front of the sensor. 

Caution: Do not install the sensor above beds, sofas, desks or in any area that people 
are likely to spend continued periods of time. If the occupant does not move within the 
delay time, an alarm will be generated when moving away from the protected area.  

Installation Instructions 

1.  To open the housing, remove the cover screw and, using a flathead screwdriver, press the 

locking tab at the side of the unit. Remove the printed circuit board (PCB) by unscrewing the 
PCB screw. 

Note: Do not touch the face of the PYRO sensor.

 

2.  Set the receiver to Registration mode. Apply battery power by removing the isolator that 

separates the battery from the contacts on the battery holder. The sensor turns on and 
sends four transmissions in order to be registered with the system. Wait for the receiver to 
indicate that the transmitter has been registered successfully. Alternatively, the EL-2650XL 
can be registered to the receiver by manually entering the transmitter's serial number.  

Note: The receiver allocates a transmitter number to each registered unit. Write this 
number and the number of the zone on the sticker provided. Affix the sticker inside the 
front cover for future reference.

 

3.  After a warm-up period of 130 sec. indicated by both LEDs' blinking, the sensor automatically 

enters Radio Mode for 4 minutes approximately and sends transmissions every 8 seconds, 
then it enters Regular mode 

– see Operation and Adjustment, Selectable Operation Modes

.  

4.  Knock out the mounting holes and test the transmitter from the exact mounting position 

before permanently mounting the unit. The EL-2650XL can be wall or ceiling mounted.  

Note: The "Alarm" arrow on the PCB (See figures 1 and 2) must point inward (i. e. 
towards the protected area).

 The recommended height is 2.2 m. 

Note: If you choose 

mounting height other than recommended (which is not advised), please perform a 
walk test to check the lens coverage. The recommended mounting height is the best in 
terms of detection area

5.  Attach the base to the wall with two screws. If using the rear tamper switch, insert a screw 

into the rear tamper hole (

see Figure 6)

 instead of the lower mounting hole. When the 

detector is removed from the wall, the screw causes the tamper release to break away from 
the back cover and the rear tamper switch is released. 

6.  Mount the PCB at the required setting using the horizontal adjustment scale and tighten the 

PCB screw – 

see Operation and Adjustment, PCB Adjustment

. Attach the front cover and 

replace the cover screw. 

Operation and Adjustment 

PCB Adjustment 

PCB adjustment enables you to angle the infrared beams by changing the position of the pyro element in relation to the lens. To adjust the PCB, loosen the 
PCB screw and slide the PCB to the required position using the PCB adjustment scale as a guide. After adjusting the board, tighten the PCB screw. Slide the 
board towards -2 to position the beams closer to the wall. Slide the board t2 to position the beams further away from the wall.  For the correct PCB 
adjustment, you must take into account the distance of the detector from the wall and the distance of the protected door/window from the detector – 

see 

Table 1 (below)

. The settings in Table 1 as illustrated in Figure 3 are relevant both to wall and ceiling mounting.

diagrams show the lens coverage pattern for the detector when incorrectly adjusted to -2 and 0. The bottom diagram shows 
the PCB correctly adjusted to +2.
