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:
Contents of the kit:
- 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
- BRSS-Ex ver.1 - 1 pc.
- Resistor C2-23H-0.25-10 kOhm ± 5% - 8 pcs.
