The Tyco 801HEX is an intrinsically safe heat detector designed for integration into marine fire alarm systems where reliable early detection in hazardous environments is critical. Carrying ATEX and IECEx certifications and rated Ex ia IIC T5, this detector is engineered for use in Zone 0/20 classified spaces where flammable gases or combustible dust may be present. As part of a vessel’s fire detection infrastructure, it plays a vital role in protecting crew, cargo, and onboard assets by providing continuous thermal monitoring in areas where conventional detectors cannot safely operate.
Key Features
✓ Intrinsically safe heat detector rated Ex ia IIC T5, with a maximum surface temperature of T100°C in dust-ignition-protected mode (Ex iaD 20), as stated in the product certification data.
✓ Operating parameters include a maximum input voltage of 28V, input current of 93mA, and input power of 0.65W — confirmed from the original product data; capacitance and inductance values are rated at zero, simplifying system loop calculations.
✓ Holds dual hazardous area certifications: ATEX (BAS01ATEX1394X, 0786-CPD-20593) and IECEx (BAS 07.0063X), confirming suitability for Group II, Category 1 GD classified environments.
✓ Designed for installation in hazardous areas such as pump rooms, tank spaces, and gas-risk zones; compatibility with specific fire alarm control panels is subject to confirmation based on vessel system configuration.
✓ Direct replacement within Tyco Safety Products fire detection ranges; suitability for a specific installation should be verified against the existing loop design and panel specifications prior to fitment.
Marine Applications
✓ Hazardous area fire detection in pump rooms, void spaces, and enclosed tank tops aboard tankers and gas carriers where flammable atmospheres may be present.
✓ Engine room and machinery space auxiliary monitoring on vessels where Ex-rated devices are mandated by class or flag state requirements.
✓ Integration into addressable or conventional fire alarm loops on offshore support vessels, platform supply vessels, and FPSOs operating in regulated environments.
✓ Cargo hold and cargo processing area fire detection on chemical tankers and LNG/LPG carriers requiring equipment rated for Group IIC gas groups.
✓ Retrofit and like-for-like replacement on vessels already equipped with Tyco Safety Products fire detection systems, maintaining certification continuity across the alarm network.
Why Marine Engineers Choose
The Tyco 801HEX is valued for its dual ATEX and IECEx certification, making it one of the more widely accepted intrinsically safe heat detectors for hazardous zone compliance in commercial and offshore marine applications. Its clearly defined electrical parameters simplify loop verification during commissioning and periodic survey.
Ideal For
Tankers, gas carriers, chemical carriers, offshore support vessels, FPSOs, platform supply vessels, and any commercial vessel requiring certified intrinsically safe heat detection in Zone 0 or Zone 20 classified spaces.
Technical Support
Technical support is available for this heat detector and related fire alarm system components, covering onboard installation guidance, detector loop troubleshooting, and remote diagnostic assistance. Support can be arranged to assist with integration queries and routine replacement procedures.
