TYCO FIRE & SECURITY GMBH
851PH
OPTICAL SMOKE AND HEAT DETECTOR WITH BASE
516.850.055
B2752FB70
The Tyco 851PH is a combined optical smoke and heat detector supplied complete with its mounting base, forming a key sensing element within a marine fire alarm system. By integrating both optical smoke detection and thermal heat sensing into a single unit, it provides dual-technology fire detection capability that reduces the risk of false alarms while improving response accuracy. Units of this type are typically installed throughout vessel accommodation spaces, machinery spaces, and control rooms where early fire detection is critical to crew safety and regulatory compliance.
Key Features
✓ Dual-function detection combining optical smoke sensing and heat detection in a single compact unit, enhancing alarm reliability across varying fire types.
✓ Specific electrical ratings, response thresholds, and sensitivity settings are subject to confirmation against the system configuration and Tyco documentation for part number 516.850.055.
✓ Designed for integration with compatible Tyco fire alarm panels and loop controllers — system compatibility should be verified against the installed panel type and loop card specification.
✓ Suitable for installation in typical shipboard environments; mounting location, area classification, and environmental suitability should be confirmed against vessel-specific fire detection drawings and SOLAS requirements.
✓ Supplied with base, simplifying direct replacement during maintenance or repair without the need for separate base procurement — reducing vessel downtime during service operations.
Marine Applications
✓ Accommodation spaces, cabins, corridors, and public areas on passenger vessels and cruise ships where early detection is essential to passenger safety.
✓ Machinery spaces and engine rooms on commercial cargo vessels, tankers, and offshore support vessels requiring robust heat and smoke sensing.
✓ Wheelhouses, navigation bridges, and control rooms where false-alarm resistance and dual-technology detection are operationally important.
✓ Offshore platforms, FPSOs, and drill ships with centralised fire alarm systems requiring addressable or conventional loop-connected detectors.
✓ Ro-Ro and vehicle deck fire detection systems on ferries and car carriers where varied fire signatures demand combined detection technology.
Why Marine Engineers Choose
Marine engineers and vessel operators select the Tyco 851PH for its reliable dual-detection design, straightforward base-mounted installation, and compatibility within established Tyco fire alarm system infrastructure — making it a practical choice for scheduled maintenance, detector replacement, and fire safety compliance management.
Ideal For
Passenger vessels, cargo ships, tankers, bulk carriers, offshore platforms, FPSOs, ferries, and any commercial vessel operating a Tyco-based marine fire alarm system requiring optical smoke and heat detection.
