The Tyco D800 Ancillary Housing (part number 557.201.401) is a protective enclosure designed to house ancillary fire alarm system components as part of the Tyco D800 fire detection platform. Manufactured in conjunction with the Hensel K 9060 housing box, this unit provides a robust, sealed installation environment for sensitive electronics within marine fire alarm systems. Rated to both IP65 and IP55, the enclosure offers reliable protection against dust ingress and water jets — critical in the demanding and variable conditions found throughout a vessel’s operational areas. Proper housing of fire alarm ancillary equipment directly supports system integrity and compliance with onboard safety standards.
Key Features
✓ Protective ancillary enclosure designed for use within the Tyco D800 fire alarm system platform, housing associated control or interface components.
✓ Dual ingress protection ratings of IP65 and IP55, providing resistance to dust and water ingress under typical marine installation conditions.
✓ Based on the Hensel K 9060 housing box format, a well-established enclosure series known for mechanical durability and reliable sealing performance.
✓ Suitable for installation in areas subject to moisture, spray, or variable ambient conditions onboard — mounting configuration and internal fittings subject to confirmation based on specific installation requirements.
✓ Supports serviceability of the fire alarm system by providing a dedicated, protected space for ancillary modules, simplifying inspection and component replacement during maintenance.
Marine Applications
✓ Installed as part of fixed fire detection and alarm systems aboard commercial vessels, supporting D800 series fire alarm panel ancillary equipment.
✓ Used in engine rooms, machinery spaces, and below-deck areas where IP-rated enclosures are required to protect fire alarm electronics from moisture and contamination.
✓ Applicable on offshore support vessels, tankers, bulk carriers, and passenger ships where Tyco fire alarm systems are deployed across multiple detection zones.
✓ Suited for accommodation and service area installations where ancillary fire alarm interfaces, relay modules, or junction components require secure, enclosed mounting.
✓ Relevant to vessel refits and fire safety system upgrades where existing Tyco D800 infrastructure is being maintained or expanded with correctly rated housing components.
