The Tyco Minerva MR601TEx (Part Number: 516.054.011.Y) is a conventional, intrinsically safe (I.S.) high-performance optical smoke detector designed for hazardous industrial and marine environments. Part of the M600Ex series under Johnson Controls / Tyco, it combines optical scatter sensing with thermal monitoring to detect both slow-smouldering and fast-flaming fires.
Key Capabilities & Design
- Heat-Enhanced Optical Sensing: An internal thermistor bridge monitors rapid temperature rises (>10°C) and boosts optical chamber sensitivity to detect hot, fast-burning fires without requiring an ionization chamber
- Smoke-Dependent Alarming: Even during rapid heat spikes, the unit requires a smoke signal to trigger an alarm, preventing false alarms from non-fire heat sources (though it will not detect clean-burning, smoke-free liquids like alcohol).
- Hazardous Area Ready: Certified for explosive gas and dust atmospheres, making it suitable for oil and gas facilities, chemical plants, and marine vessels.
- Base Compatibility: Designed to mount onto compatible intrinsically safe bases such as the 5BEx or MUBEx (Part Number 517.050.610).
