Photoelectric, thermal (135°F rate-of-rise), and infrared sensors share one head and one SLC address. Algorithm-driven cross-sensor logic rejects nuisance triggers while keeping fire response fast.\u003c\/p\u003e\u003cp\u003eThe ivory finish supports CLIP backwards-compatibility on legacy E3 and S3 loops, the detector can drop onto an existing CLIP-protocol loop without forcing a wholesale conversion. Specs are otherwise identical to the white MCS-PTIR. Single Velociti or CLIP address per detector.\u003c\/p\u003e\u003ch2\u003eWhy ivory + CLIP, retrofit-grade detector\u003c\/h2\u003e\u003cp\u003eIvory exists for color-matching retrofits where existing ceiling detectors are ivory. CLIP backwards-compat is the protocol layer that makes the SKU usable on old E3 \/ S3 loops still running ASD-PL2F-vintage CLIP detectors. The combination, color match plus protocol compatibility, is the only way to drop a modern multi-criteria detector into a legacy install without wiring rework.\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. The MCS-PTIR-IV algorithm waits for two of three sensors to agree before alarming. The detector also reports distinct smoke and heat events, allowing different evacuation strategies on photo vs thermal trips.\u003c\/p\u003e\u003ch2\u003eAir velocity limit vs MCS-COF3\u003c\/h2\u003e\u003cp\u003eRated 0 to 300 ft\/min. For HVAC paths or higher-velocity ceilings plus CO coverage, specify MCS-COF3 (white) or MCS-COF3-IV (ivory) instead.
