1 General Information

Passive infrared detector «Foton-SH2» (hereinafter, the Detector) 

is intended for detecting intrusion into a protected premises through 
door or window openings and generating an alarm message by output 
relay contacts opening. The Detector generates «Sabotage» message 
by microswitch contacts opening.

The Detector has immunity to interference caused by small animals 

and ambient light.

2 Features of the Detector

- Dual-element pyrodetector.
- «Vertical curtain» detection zone.
- Microprocessor-based signal processing.
- Temperature compensation of the detection sensitivity.
- The maximum Detector installation height is up to 5 m.
- Possibility of LED indication disabling.
- Two-way installation using four fastening surfaces of the Detector 

base: either above the protected opening, or in the corners of window 
openings, door cases, etc.

- High resistance to ambient light – 12000 lx.
- Immunity to electromagnetic interference.
- Case tamper protection.
- High immunity to the ambient light (up to 12 000 lx).
- High immunity to electromagnetic interferences.
- Tamper protection.

5 LED Indication

LED indicator is used for the Detector status displaying. For LED 

indication disabling remove jumper IND. Set the jumper on one of the 
male pins for the further usage during testing.

6 Choosing Place of Installation

When choosing locations for the Detector installation, it is advisable 

to take note of the fact that the detection zone may be limited by  
non-transparent objects (curtains, curtain holders, door trims, etc), 
as well as glass partitions. There must be no air conditioners, space 

heaters or heating radiators in the Detectors’ detection zone. 

Maximum installation height of the Detector is 5 m. Alarm loops should 

be wired far enough from power supply cables. Variants of installation 
are shown in Figure 1.

8 Installation

- Remove the Detector cover by pressing on the back wall of the 

Detector base (Figure 3) and pressing the edges of the cover by the 
fingers of the other hands at the points shown in Figure 4, put off the 
cover.  

- Insert a screwdriver with a flat drive blade between the printed 

circuit board (PCB) and the back wall of the base, depress the base 
wall and remove the PCB (Figure 5).

- Depending on the chosen location of the Detector, determine the 

Detector base sides for fastening to the installation place and drill 
fastening holes or press them out with a screwdriver (Figure 6).

- Insert wires through the openings for wiring. Leave several 

centimeters of the wire for plugging to the terminal boards.

- Fasten the base on the chosen place.
- Install the PCB in the base and latch it on both sides.

- Fulfill connections in accordance with Figure 7.
