Three independent signals cross-reference in panel-side algorithms to reject nuisance triggers, theater smoke, dust kicked up by HVAC, cooking aerosols, while staying sensitive to real fire signatures.\u003c\/p\u003e\u003cp\u003eThe detector reports distinct smoke and heat alarms to the panel, so the system can map different evacuation strategies: local alarm on photoelectric trip, full general evacuation on thermal trip. Single Velociti address per detector. White finish.\u003c\/p\u003e\u003ch2\u003eThree sensors, distinct alarms, when this design wins\u003c\/h2\u003e\u003cp\u003eTheater stages, hotel lobbies, hospital common areas, performance venues, places where nuisance smoke is expected but real fire still needs immediate response. Single-sensor photoelectric detectors trip on theater fog and trigger costly evacuations; thermal-only misses smouldering fires too early. The MCS-PTIR algorithm waits for two of the three sensors to agree before alarming, which sharply reduces false trips without losing time on real fires.\u003c\/p\u003e\u003ch2\u003eAir velocity limit vs MCS-COF3\u003c\/h2\u003e\u003cp\u003eThe MCS-PTIR is rated 0 to 300 ft\/min. For HVAC paths or higher-velocity ceilings (up to 4,000 ft\/min), specify the MCS-COF3, its sensor stack includes a CO cell and the air velocity envelope is wider. Pick by environment first: PTIR for room\/lobby ceilings, COF3 for duct and high-velocity areas requiring CO coverage.\u003c\/p\u003e\u003ch2\u003eCompatible panels and listings\u003c\/h2\u003e\u003cp\u003eGamewell-FCI Velociti SLC panels: E3 Series, S3 Series, GWF-7075.
