Alarm loops extension relay BRSS-Ex.

BRSS-Ex was designed to receive alarm signals from detectors installed in hazardous areas and provide power supply to them.

BRSS-Ex is an intrinsically safe barrier that must be installed OUTSIDE of the hazardous area. BRSS-Ex sends information about the status of intrinsically safe loops according to version:

  • control panel Ladoga-A;
  • any other control addressable panel via relay module ("BRV-A" ver.2)
  • any other control addressable panels via broadcasting of the loops resistance from hazardous area
Contents of the kit:
  • Alarm loops extension relay BRSS-Ex - 1 pc.
  • Resistor C2-23H-0.25-10 kOhm ± 5% - 8 pcs.
  • Resistor C2-23H-0.25-2 kOhm ± 5 % - 2 pcs.
  • Fasteners.
