Description
AUTRONICA
TYPE: BZ-32
ZENER BARRIER UNIT
CONTAINING BARRIERS Z667/EX
BASEEFA NO. EX 822097
The Autronica BZ-32 is a Zener Barrier Unit designed to provide intrinsically safe isolation within marine fire alarm systems. Housing Z667/EX barriers and certified under BASEEFA No. EX 822097, this unit ensures that electrical energy entering hazardous areas remains within safe limits, protecting both personnel and sensitive detection equipment. It is a critical safety interface component used where fire detection circuits must cross into potentially explosive atmospheres onboard ships and offshore installations. Reliable intrinsic safety barriers are fundamental to maintaining SOLAS-compliant fire detection system integrity in such environments.
Key Features
✓ Zener barrier design provides intrinsically safe signal isolation, limiting voltage and current in hazardous area circuits to prevent ignition risk.
✓ Contains Z667/EX barriers; certified under BASEEFA No. EX 822097 — exact electrical ratings subject to confirmation against original documentation.
✓ Designed for integration within Autronica fire alarm and detection systems; compatibility with specific panels or loop controllers should be confirmed for the target installation.
✓ Suited for installation in control or safe-area panels feeding detector circuits routed into classified hazardous zones such as engine rooms, pump rooms, or cargo spaces.
✓ Replacement of this barrier unit supports continued intrinsic safety compliance and helps restore full system functionality following fault diagnosis or scheduled maintenance.
Marine Applications
✓ Tankers and gas carriers where fire detection circuits must interface with hazardous zone areas including cargo pump rooms and void spaces.
✓ Offshore supply vessels and platform support vessels requiring intrinsically safe fire alarm circuit isolation.
✓ Ro-Ro and vehicle carriers where fire detection systems span both safe and potentially explosive atmosphere zones.
✓ Bulk carriers and general cargo vessels with Autronica fire alarm systems installed in compliance with SOLAS Chapter II-2 requirements.
✓ Naval auxiliaries and specialist vessels where certified intrinsic safety barriers are mandated by class or flag state regulations.
