The Autronica BN-180 AutroKeeper is a specialized loop access and redundancy module for AutroSafe fire detection systems. Two BN-180 units allow primary and secondary loop controllers to share a single detection loop, providing Dual Safety/redundant fire detection without duplicating the loop cabling and detectors.

Key Features

• Provides redundant access to one fire detection loop.
• Uses two BN-180 units—one primary and one secondary.
• Automatic takeover by the secondary system if the primary loop controller fails.
• Eliminates the need for a second complete set of detection loops, reducing cabling and detector duplication.
• Provides galvanic isolation between the standby loop controller and detection loop.
• Automatic addressing and short-circuit protection.
• DIN-rail mounting for installation inside control cabinets.
• Supports SOLAS Dual Safety / Safe Return to Port requirements.

Typical Applications

• Marine fire detection and alarm systems
• SOLAS Safe Return to Port installations
• AutroSafe Dual Safety systems
• Redundant fire detection loop control
• Passenger ships and vessels requiring high fire-system availability
• Offshore and other safety-critical fire detection installations
