MADE IN CANADA

English

The Paradox PRO Plus with Pet Immunity (476PET) is a state-of-
the-art analog detection system that incorporates the following 
unique features:

• Patented Auto Pulse Signal Processing with two 

programmable levels

• Specially designed lens provides pet immunity up to 18kg (40lbs)
• Improved RFI and EMI rejection with metal shield
• Automatic Temperature Compensation
• High density reflow SMD design

Installation

At the recommended height of 2.1m (7ft) ± 10%, the 476PET motion 
detectors provide full coverage from 1.5m (5ft) to 11m (35ft) and up to 
15m (50ft) for the center beams. 

Avoid placing the detector within proximity of reflective surfaces; 
direct air flow from vents, fans, and windows; sources of steam/oil 
vapor; infrared light sources; and objects causing temperature 
changes such as heaters, refrigerators and ovens. Do not place 
objects or furniture higher than 0.9m (3ft), which a pet can climb 
onto (e.g. a cat on a couch), within 2.1m (7ft) of the detector. In 
addition, do not aim the detector at a stairway a pet may have 
access to.

After selecting the detector's location, carefully remove the PCB 

E

 by loosening the PCB screw 

D

 and drill holes for the screws as 

shown in Figure 1 and Figure 2.  Run the wires through the two 
entry holes labeled 

C

 (see Figure 2) and connect them according 

to the markings on the plastic back or as shown in Figure 1.

Do not touch the sensor surface as this could result in a 
detector malfunction. If necessary, clean the sensor 
surface using a soft cloth with pure alcohol.

Pet Immunity

An animal’s immunity to false alarms depends on its size, 
temperature, and length of coat. Longer hair and smaller size 
make an animal more likely to be immune, while shorter hair and 
larger animals are more likely to create a false alarm. For animals 
that require a higher immunity level, consider using our DG75 
dual-sensor motion detector with 40kg (90lbs) pet immunity.

The 476PET pet immunity feature has not yet been investigated 
by UL.

PCB Height Adjustment

The 476PET is designed for optimal performance at a height of 
2.1m (7ft), but can be installed lower or higher. After you have 
installed the detector, ensure that the adjustable height markings 

on the left side of the PCB match the tab 

D

 inside the back cover 

(see Figure 2).

For example, if the detector is installed at a height of 2.1m (7ft), the 
PCB should then be adjusted to 2.1m (7ft) (see Figure 4). Align the 
desired marking (height) with the back cover’s plastic tab.

If another installation height is called for, readjust the PCB 
accordingly. Any PCB adjustments should be followed by a walk-
test of the protected area. Walk-testing verifies that the required 
coverage is in place.

J1 - LED Setting

When the motion detector detects movement, the 
green LED will illuminate for 3 seconds. To disable 
the LED display, remove jumper J1 (see Figure 1). 

ON (default) =

 This will enable the green LED                   

OFF =

 This will disable the green LED

J2 - Slow / Fast Mode

Jumper J2 is located inside the metal shield and is 
factory-set to the "ON" position (fast mode), which is 
recommended for the majority of installations. The 
use of slow mode (jumper J2 "OFF”) is suggested in 
areas where the incidence of false alarms may be 
greater. Use a small screwdriver to gently pry off the 
metal shield 

F

 to access jumper J2. Please refer to 

Figure 1. 

If the animal is large (close to 18kg / 40lb) with short hair, the 
sensitivity should be reduced (set J2 to slow mode).

ON (default) =

 Fast Mode (high sensitivity)

OFF =

 Slow Mode (low sensitivity)

WARNING! In Slow mode, the detector range may be 
reduced.

Walk-testing

In order to test the detector, walk through the area protected by 
the detector. If the Green LED illuminates for 3 seconds, the 
detector is working. To test an animal’s immunity, have the animal 
walk across the detection path. If the light does not illuminate, the 
animal is immune to detection. When walk-testing, always move 
across the detection path, not towards the detector.
