The BN-320/SV is connected to the detector loop, and is designed for use with the AutroSafe Interactive Fire Alarm System, and AutroMaster5000.
Typical applications are:
Interface for Section Valves
Interface for extinguishing agents such as CO2 release, Halon release, Foam, Inergen release etc.
Interface for dampers
Interface for fans
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
