Tyco 601PH-M Conventional Marine Fire Detection Optical Smoke Detector

The Tyco 601PH-M forms part of the Minerva Series 600 range of plug-in conventional detectors engineered for ceiling-mounted fire detection on marine vessels, offshore platforms, and shipboard environments. Utilizing a light-scattering optical chamber enhanced by internal thermal sensing algorithms, the 601PH-M behaves as a standard photoelectric detector under normal ambient conditions. Upon sensing a rapid rise in ambient temperature, its optical sensitivity dynamically increases to confirm genuine fire conditions—allowing fast detection of clear-burning fires that traditionally required ionization chamber detectors. Built with a patented “mousehole” chamber geometry that maximizes signal-to-noise ratio and draws slow-moving smoke into the sensing element, the 601PH-M offers high resilience against dust, insects, and humidity while maintaining full approval from major marine classification societies.
