Designed to monitor conventional fire detectors of the current increase type and to convey their status to the fire alarm control panel.
For up to 32 conventional detectors. Conventional loop voltage is selectable to 15 or 24 V. Modular unit for mounting on DIN rail.
The conventional detectors are connected to a two-wire sub loop. The sub loop is monitored for broken line by an end of line unit BNY-330. As default a short circuit of the sub loop will give a fault warning, but the unit may be configured to give an alarm instead.
