Tyco 516.039.003 S251F+ Addressable Flameproof Triple IR Flame Detector This unique detector may be interfaced with the LPCB approved MINERVA and UL/FM approved TFX range of analogue addressable fire control equipment. Communication to these devices is achieved over a 2 core cable. Using the S251i+ in conjunction with System 602 (Certification for hazardous areas), up to a maximum of 10* detectors may be addressed and identified on a single pair of wires within the hazardous area (zone 0). Up to 50 off S251f+ detectors can be addressed and identified on a single pair of wires within the hazardous area (zone 1). Use of these two models can significantly reduce cabling costs without loss of system integrity. Using technologies developed over more than 30 years, the microprocessor based Minerva S860 series flame detectors combine solar blind sensing of UV radiation and narrow waveband sensing of flame specific IR radiation to provide a reliable means of detecting flaming fires. The detectors are supplied in a Flameproof (Explosion proof) housing making them suitable for use in classified Hazardous Areas. They provide an easy interface to the range of Tyco conventional and analogue addressable panels. Key Features: Unrivalled black body rejection over a wide range of source temperatures.
