TYCO
PART DESCRIPTION: 4B-DHM HEAD MOUNT
PART NUMBER: 517.050.051
VP: 5544/004
The Tyco 4B-DHM Head Mount is a detector head mounting component designed for use within marine fire alarm systems. It provides a secure and stable interface between the detector head and its installation surface, ensuring consistent contact, alignment, and signal integrity within the wider fire detection network. Reliable mounting hardware of this type is fundamental to the operational effectiveness of any shipboard fire alarm system, supporting the continuous monitoring requirements demanded by maritime safety standards.
Key Features
✓ Designed as a dedicated head mount for Tyco fire detection components, ensuring a precise and secure fit for compatible detector heads.
✓ Exact electrical and dimensional specifications are subject to confirmation based on system configuration; compatibility should be verified against the installed Tyco fire alarm panel and detector series.
✓ Intended for integration within Tyco fire alarm systems; system-level compatibility depends on the specific panel and detector configuration onboard.
✓ Suitable for installation in typical shipboard environments; mounting location and area suitability should be assessed in line with onboard installation guidelines and applicable SOLAS fire detection requirements.
✓ Acts as a serviceable replacement component, allowing maintenance teams to restore detector mounting integrity without replacing entire detector assemblies, supporting efficient planned maintenance schedules.
Marine Applications
✓ Fire detection systems aboard commercial cargo vessels, tankers, and bulk carriers requiring reliable detector head mounting solutions.
✓ Passenger vessels and ferries where fire alarm system integrity is critical to SOLAS compliance and the safety of crew and passengers.
✓ Offshore platforms and support vessels utilising Tyco fire alarm infrastructure in accommodation, machinery, and cargo spaces.
✓ Naval and coast guard vessels where robust and secure detector mounting is essential within demanding operational environments.
✓ Replacement and refit projects across a wide range of vessel types requiring like-for-like Tyco fire alarm system spare parts.
