Autronica BN-303 PCB BNA-304 7212-406.0002 Monitored Input

For interfacing switches and 3rd party detectors with relay outputs to Autronica’s interactive fire detection systems. For Autroprime (1.1.0 or newer versions) and AutroSafe (4.3.1 or newer versions). With SelfVerify.

The unit hosts several I/O functions. The I/O unit’s dipswitch setting determines which function is assigned to the inputs/outputs. BN-303 provides 6 different functions.

Mounting :- Wall mounting, 100mm bolt space

 Power:-  Unit connects to AL_Com only

Voltage:- Supplied from detection loop

 Peak current consumption (during communication) :- 359μA

Average current consumption :- <60μA

Temperature range :- -25 to +70 °C

Humidity:-  10% - 95% RH (non-condensing)

Degree of protection Membrane glands:- IP54

PG glands (PG-13,5):- IP67

Cable terminals :- Max 2.5mm² single core wires

Maximum input cable length:- 10m, non-shielded or shielded. End termination 2kohms +/-5%

Threshold :- Short-circuit: 0-235 Ω , Activate: 260-1000 Ω , Normal: 1200-4800 Ω , Open circuit: 5400-∞ Ω

For interfacing and controlling external units to Autronica’s interactive fire detection systems. For Autroprime (version 1.1.0 or newer) and AutroSafe (version 4.3.1 or newer). With SelfVerify.

The SelfVerify function ensures the highest grade of reliability and reduces the need for manual testing because the panel is able to contiuously and automatically check all units that include this function.
