Function

ABV-300/D is designed with state of the art technology to satisfy all the requirements of a reliable fire protection unit. The control unit continuously monitors that the power supply and current values are normal.

A green LED indicates that the power supply is switched on.

The control unit is connected to the smoke detectors by means of a two-wire loop.

Up to 20 detectors can be connected to the same control unit. An end resistor should be connected to the last detector to end the loop.
