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).
2 monitored inputs.
1 output with potential free changeover contact.
Connected directly to the detection loop.
Short circuit isolator in each unit.
