Design to receive alarm signals from the detectos installed in hazardous areas and to provide power supply to detectors.
BRShS-Ex is intrinsically safe barrier that must ve installed OUT of the hazardous area.
BRShS-Ex sends information about status od intrinsically safe loops according to version:
- control panel Ladoga-A (the most detailed information);
- any other control addressable panel via relay module ("BRV-A" ver.2)
- any other control addressable panels via brooadcasting of the loops resistance from hazardous area.
