The Thorn Security IF800EX is an addressable interface module manufactured by Tyco Safety Products, designed to integrate third-party devices and ancillary equipment into marine fire alarm and detection systems. Operating within defined voltage and current parameters as indicated on the unit label, it enables bi-directional communication between fire alarm control panels and field-connected devices. Forming a critical part of a vessel’s Fire Alarm System, the IF800EX supports reliable signal monitoring and output control, ensuring that detection and suppression trigger circuits operate with precision in compliance with onboard safety requirements.
Key Features
✓ Dual terminal block configuration (TB1 & TB2) with defined input and output voltage of 28V, supporting controlled loop integration with monitored current and power ratings as labelled on the unit.
✓ Additional SK1 output rated at 28V with low power consumption (PO=145mW), suitable for driving ancillary devices or auxiliary outputs within the fire detection loop.
✓ Designed for compatibility with Thorn Security and Tyco Safety Products addressable fire alarm systems; system panel compatibility subject to confirmation based on vessel configuration.
✓ Compact module format suitable for installation within fire alarm control cabinets or field enclosures; mounting location and environmental suitability depend on installation design and applicable SOLAS fire detection requirements.
✓ Direct replacement part referenced by part number 514-001-062, supporting maintenance and like-for-like swap-out during scheduled service or corrective maintenance routines onboard.
Marine Applications
✓ Cargo vessels and bulk carriers requiring addressable fire detection loop expansion to monitor cargo holds, engine rooms, and accommodation spaces.
✓ Offshore support vessels and platform supply vessels where fire alarm system integrity is critical to personnel safety and regulatory compliance.
✓ Passenger ferries and ro-ro vessels with multi-zone fire alarm architectures requiring reliable interface modules to manage ancillary device outputs.
✓ Naval auxiliary and government vessels utilising Tyco or Thorn Security fire detection infrastructure across multiple decks and compartments.
✓ Tankers and chemical carriers where fire alarm interface modules form part of integrated detection and suppression system control circuits in hazardous areas.
