1 General Information
Passive infrared detector «Foton-21» (hereinafter, the Detector) is intended
for detecting intrusion into a closed protected space and generating an alarm
message by relay output contacts opening.
The Detector ensures tamper protection by means of «Tamper» microswitch
relay contacts opening.
The Detector is resistant to the ambient light impact and radio interference.
The Detector ensures absence of false alarms cased by movement of small
animals: mice, rats, birds in cages at a distance to them not less than 2.5 m.
The Detector is distinct in: attractive design, ease of installation and
maintenance.
2 Features
- The Detector is designed for ceiling mounting.
- Sensing elements – two dual-element pyrodetectors.
- Digital temperature compensation.
- Unique lens provides wide-range detection zone with high filled density,
ensuring reliable detection of the intrusion in any direction.
- Protection against intrusion of insects to a pyrodetector.
- Microprocessor-based signal processing.
- Choosing of installation height as well as the following modes: testing, alarm
memory, and LED indication.
- Self-test mode ensuranse.
- The Detector is supplied from DС current supply unit with output voltage
(9 … 15) V.

Installation Guide
When choosing the Detector installation place, it is advisable to take note
of the fact that the detection zone may be limited by non-transparent objects
(curtains, houseplants, cabinets, bookcases, etc.), as well as by glass and mesh
partitions. There must be no windows, air conditioners, space heaters or heating
radiators in the PIR-detection zone.
The Detector wires should be laid far enough from power supply cables.
7 Installation of the Detector
- Put off the Detector cover by it’s turning counter-clockwise until tight to the
recess on the external ring of the Detector base and then rise the cover (Figure 2).
Figure 2 – Base and cover of the Detector
- Put off the printed circuit board (PCB) by unfastening the latch, located
on the base.
- Drill the holes in the base (See Figure 3) for the Detector wiring and
fastening the base.
- Choose the place of installation, mark the places for mounting holes with
regard to the openings on the Detector base, drill holes in the place of installation.
- Insert wires into the hole in the base leaving several centimeters for fixation
inside the case and connection to the leading-in sockets.
- Fix the base of the detector on the chosen place.
- Set down PCB on their places.
8 Connection
- Leading-in sockets for the Detector connection are located on the PCB.
- Fulfill connections in accordance with Figure 3а (for hooking up to single
AL) or Figure 3b (to single tamper control AL).
- Set up the DIP-switches «1», «2», «3», «4» in accordance with particular
application conditions and Cl.9 of herein Installation Guide.
- Install the Detector cover on it’s place. For this purpose insert the bulge
to the recess on the base external ring, push the cover and turn it in clockwise
