The Autronica BNB-330A Conventional Loop Interface is a two wire interface unit for interfacing conventional detectors and manual call points. The BNB-330A is used on Autronica’s interactive fire detection systems. The Autronica BNB-330A replaces the BNB-330 and may be used on all the same systems.
The Autronica BNB-330A has different mechanical measurements then the BNB-330 and will not fit directly into the BN-330 enclosure. A special DIN rail (US-852/1) and brackets (US-852/2) must be used for fitting of the BNB-330A in this enclosure.
Features Local-powered (requires external 24V power supply) Short and open circuit detection on conventional detection loop Ground fault detection on conventional detection loop via fire panel ground fault detection Up to 32 Detectors/Manual Call Points on one conventional detection loop Interfaces conventional detectors and manual call points from Autronica and other leading manufacturers, refer to voltage vs. current chart Uses active EOL unit Addressable loop technology Automatic addressing Proven technology TS35 DIN rail mounted Indicators for power, alarm and fault on the conventional detection loop Galvanic isolation between power supply and detector interface Monitored power input, fault signaled if <18V for 24 VDC Monitored power input, fault signaled if <12V for 15 VDC Backbone bus distributing external 24V bus via DIN rail to up to 20 units, reducing installation time.
