BRSS-Ex ver.2

Code 00000011536

Alarm loops extension relay BRSS-Ex ver.2.

BRSS-Ex ver.2 was designed to receive alarm signals from detectors installed in hazardous areas and to provide power supply to them.

BRSS-Ex ver.2 is an intrinsically safe barrier that must be installed OUTSIDE of the hazardous area. BRSS-Ex ver.2 sends information about 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:
