Addressable control unit for monitoring of extinguishing equipment. The unit has two monitored inputs: A)extinguishing media, B) trigger gas.
If the system does not have trigger gas, input B can be disabled by connecting a 2k resistor on the terminals. In addition, the unit has one monitored relay output.Note that the extinguishing control application requires feedback within 10 seconds after the release of the extinguishing media to avoid a faulty release message.

The extinguishing equipment is powered from a separate 24 VDC supply. The interface unit is used in the AutroSafe interactive fire detection system, and it is connected directly to a detection loop. BN-221/01 monitors the presence of power supply. The unit will give a fault warning in case of power failure or loss of power.
