The Det-Tronics PM-5MPX Dual Spectrum® flame detector is optimized for the rigorous semiconductor fabrication industry, which is beset with many hazards that result in stringent requirements for fire protection safety systems. Flame detection requirements for this industry are specific: Factory Mutual Approvals (FM) addresses the detailed specific requirements for this application in Factory Mutual Loss Prevention Data Sheets 7-7/17-12, Semiconductor Fabrication Facilities. The PM-5MPX meets both industry and FM requirements.

A typical accident scenario involves a solvent or plastic wetbench component being ignited by faulty or misused electronics. If not detected and extinguished quickly, such fires and their combustion byproducts can severely contaminate the clean room and other facilities resulting in large production losses. The detector incorporates unique Dual Spectrum® infrared sensor technology, which establishes a new standard in flame detection and false alarm immunity. The polypropylene enclosure enables the detector to be utilized in both solvent or chemical etch wet benches.
