711H TYCO Conventional Rate-of-Rise Heat Detector

The 711H TYCO (Model / Part No: 711H, Marine Order No: 516.800.003) is a high-reliability conventional rate-of-rise heat detector engineered by Tyco Safety Products (Johnson Controls) for marine vessel fire detection and industrial safety systems. Designed to monitor rapid ambient temperature increases alongside a fixed upper temperature limit, the 711H TYCO provides fast fire warning response in environments where optical smoke detectors are prone to false alarms caused by steam, dust, or combustion fumes.

Equipped with a dual-thermistor sensing circuit, the 711H TYCO continuously evaluates ambient thermal conditions, triggering an alarm state when rapid temperature spikes or a fixed threshold (Class A1R) is reached. Mounted on standard Tyco 700 Series bases (such as 4B or 5B bases), it provides essential fire safeguard coverage across ship engine rooms, vessel galley spaces, boiler plants, and industrial processing facilities.

Key Features of the 711H TYCO

• Dual Rate-of-Rise & Fixed Heat Detection: Triggers an alarm when temperature rises rapidly or reaches a fixed Class A1R temperature threshold.

• Low False-Alarm Susceptibility: Ideal for dirty, dusty, or humid environments where optical smoke detectors cause nuisance alarms.

• High-Visibility LED Alarm Status: Integral 360° red LED indicator lights brightly upon fire alarm condition activation.

• Marine Approved Construction: Fully certified under MED (Marine Equipment Directive), DNV, ABS, and Lloyd’s Register for shipboard installation.

• Standard 700 Series Base Fit: Compatible with Tyco 4B, 4B-C, and 5B detector bases for fast twist-lock installation and servicing.

• Remote Indicator Output: Supports connection of external remote LED indicator lamps for hidden ceiling voids or cabin doors.

Primary Applications

• Marine Telemetry & Vessel Safety: Fire detection in vessel engine rooms, thruster compartments, steering gear rooms, and cargo holds

• Industrial Processing Plants: Thermal monitoring in boiler rooms, power generation plants, paint shops, and dusty workshop areas

• Commercial Buildings: Heat detection in kitchens, boiler enclosures, and parking garages unsuitable for smoke sensing
