Autronica BN-320/GMU-XS AutroSafe General Control Unit


The Autronica BN-320/GMU-XS is a general control unit that is designed for use in maritime installations. The BN-320/GMU-XS is connected to the detector loop, and it is designed for use with the Autrosafe Interactive Fire Alarm System and AutroMaster5000. The Autronica BN-320/GMU-XS is used as an interface for a general monitoring and control to front external equipment on to the detector loop.

Input A is used for confirming activation (manual or automatic.
Input B is used for reporting fault conditions (power fault and/or unit fault).
An open circuit (loss of the 2k on the inputs gives fault warning).
