UNIVERSAL DETECTOR BASE
517-050-017
The Tyco FC450UB 5B is a 5-inch universal detector base designed to provide a secure and reliable mounting interface for compatible fire detectors within marine fire alarm systems. As a core component of the detection network, the base ensures consistent electrical connectivity and mechanical stability between the detector head and the panel wiring, making it essential to the integrity of onboard fire detection coverage. Correct base selection and installation directly supports system reliability in safety-critical environments governed by SOLAS fire detection requirements.
Key Features
✓ Universal detector base design accommodates compatible Tyco fire detector heads, offering installation flexibility across system configurations.
✓ 5-inch (5”) base diameter provides a standard footprint suitable for typical deckhead and bulkhead mounting arrangements found onboard vessels.
✓ Engineered for integration within Tyco fire alarm system infrastructure; specific panel and loop compatibility subject to confirmation against installation documentation.
✓ Suitable for installation in a range of onboard spaces; exact environmental ratings and certifications should be verified against the relevant product datasheet prior to fitment.
✓ Replacement of detector bases is a routine element of fire system maintenance, ensuring continued loop integrity and reducing the risk of contact or connectivity failures over time.
Marine Applications
✓ Accommodation and cabin spaces aboard passenger ferries, cruise ships, and ro-ro vessels where addressable or conventional fire detection is required.
✓ Engine control rooms, machinery spaces, and auxiliary equipment rooms on cargo ships and tankers requiring reliable detector mounting solutions.
✓ Offshore platforms and support vessels where fire alarm system integrity is subject to rigorous safety management requirements.
✓ Wheelhouses, navigation spaces, and crew quarters on workboats and offshore supply vessels fitted with Tyco fire detection infrastructure.
✓ Retrofit and upgrade projects where existing detector bases require like-for-like replacement to maintain system continuity and compliance.
