The Autronica BNA-320/10 is the PCB/interface board used in the BN-320 interface and monitoring/control unit. It connects external fire-detection or monitoring equipment to the Autronica interactive detection loop and provides two monitored inputs and one relay output.
Features
- Two monitored inputs for external equipment/status signals.
- One relay output for control applications.
- Connected directly to the Autronica detector loop.
- Each BN-320 uses one address on the detection loop.
- Input circuits can monitor open/closed contacts and fault conditions using defined resistor configurations.
- Suitable for interfacing equipment such as AutroFlame, AutroBeam and AutroSense detectors.
- Supports applications requiring activation, fault and status feedback.
- Used in legacy AutroSafe installations; Autronica documentation identifies BN-304/BN-305 as substitute products for the discontinued BN-320.
Typical Applications
- Autronica AutroSafe fire detection systems
- AutroFlame detector interfacing
- AutroBeam detector interfacing
- AutroSense aspirating smoke detector interfacing
- Fire damper monitoring/control
- Ventilation and fan control
- Lift and hatch control
- External equipment fault/status monitoring
- Marine and shipboard fire detection systems
- Industrial fire & gas installations
