UNIVERSAL DETECTOR BASE
WITH CABLE
C-068 WIRE LINE UNIT
The Tyco DHM-5B is a deck head mounting universal detector base supplied with cable, forming a critical interface component within marine fire alarm systems. Designed to securely mount fire detectors to overhead surfaces onboard, this base ensures reliable electrical connection and mechanical retention of compatible detector heads. As part of a broader fire alarm system, it plays a fundamental role in maintaining continuous smoke or heat detection coverage across protected spaces — a key requirement for vessel safety and regulatory compliance onboard commercial and working marine vessels.
Key Features
✓ Universal detector base design compatible with a range of Tyco fire detector heads, offering flexible installation options across different alarm system configurations.
✓ Deck head mounting format, engineered for overhead installation on ceilings and structural panels in typical onboard protected spaces.
✓ Supplied complete with cable (C-068 Wire Line Unit), supporting straightforward integration into existing or new fire alarm wiring circuits.
✓ Part of the Tyco DHM series, suitable for use in marine fire detection systems where reliable loop wiring and detector retention are essential operational requirements.
✓ Service and replacement considerations are straightforward given the universal base format, making it a practical choice for maintaining fire alarm system integrity during scheduled maintenance or detector upgrades.
Marine Applications
✓ Accommodation spaces and cabins aboard passenger ferries, cruise vessels, and cargo ships requiring distributed fire detector coverage.
✓ Engine control rooms and machinery spaces where overhead-mounted detectors are installed as part of fixed fire detection systems.
✓ Offshore platforms and support vessels where fire alarm system reliability is critical to crew safety and operational continuity.
✓ Tankers and bulk carriers requiring SOLAS-compliant fire detection installations across multiple protected zones and decks.
✓ Naval auxiliaries, workboats, and specialist vessels where Tyco fire alarm system components are used as part of certified detection infrastructure.
