Alarm loops extension relay BRSS-Ex ver.1.

BRSS-Ex ver.1 was designed to receive alarm signals from detectors installed in hazardous areas and provide power supply to them. BRSS-Ex ver.1 is an intrinsically safe barrier that must be installed OUTSIDE of the hazardous area.

BRSS-Ex ver.1 sends information about the status of intrinsically safe loops according to version:

  • control panel Ladoga-A (the most detailed information)
  • any other addressable control panel via relay module ("BRV-A" ver.2)
  • any other addressable control panels via broadcasting of the loops resistance from hazardous area
Contents of the kit:

  • BRSS-Ex ver.1 - 1 pc.
  • Resistor C2-23H-0.25-10 kOhm ± 5% - 8 pcs.
  • Resistor C2-23H-0.25-2 kOhm ± 5 % - 5 pcs.
