The detectors operate as a part of system controlled by the Rubezh-2OP prot.R3 receiving and control alarm panel.

The detector’s power supply is provided via unipolar addressable communication line.


Communication LED indicator is available on the detector’s cover:

  • in stand-by mode - flashes once per 4-5 sec.;
  • in alarm mode - flashes twice per sec.;
  • in "Test" mode - rapid flashing during 2-3 sec after Test button pressing.
Detector's LEDs may be automatically switched off. When the LEDs are activated, the detector displays its own state, whether the security function is activated or not.

Detector functioning may be tested using OT-1 optical tester.
