INF-PET

 

The INF-PET is a passive infrared detector designed for use with the infinite alarm system. The detector is 
designed for pet installations and implements a feature to combat the problem of multiple transmissions, 
which drastically reduce the life of the batteries. After a transmission is made, the INF-PET initiates a four-
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 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 which comes in direct 
contact with radiators, heating/cooling 
ducts and air conditioners. 

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 isolator that separates the battery from the contacts on the battery holder. 

4. 

Place the Mode jumper over pins 2 & 3 (Registration Mode); the LED flashes. 

Note: Install the Mode 

jumper only after applying battery power.

 

5. 

Set the receiver to Registration mode and wait for the receiver to indicate that the transmitter has been 

registered successfully. Alternatively, the INF-PET 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.

 

6. 

Remove the jumper and place it over one pin for storage - 

see Mode Jumper Safeguard

7. Choose

 

an appropriate mounting height (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. 

Operation and Adjustment 

Warm-Up Time:

 The detector will need to warm up for the first 90 

seconds after applying power. 

Setting the pulse counter: 

The pulse counter determines the 

amount of pulses that need to be received for the detector to generate 
an alarm. To set the pulse counter, refer to Table 1. 

Vertical Adjustment: 

To position the PCB, turn the Easy Lock counter-clockwise and slide the PCB up or 

down to the required setting using the vertical adjustment scale. The detector’s coverage area is 12m x 12m 
when the PCB is positioned at -4. This is also the setting for maximum pet immunity. Slide the PCB up 
towards the -8 position to decrease the coverage area bringing the beams closer to the mounting wall.
