Its function is to periodically interrupt the UV sensor’s view of the flame, allowing the Flame Safeguard amplifier to confirm the detector’s proper operation. Powered by 120 VAC at 50\/60 Hz, the assembly includes both the electromagnetic coil and the mechanical shutter mechanism in one integrated module. This component is typically mounted inside the flame detector housing and operates automatically as part of the self-check circuit cycle. The 190971B was supplied as an OEM replacement part and is now discontinued by the manufacturer, though it remains critical for maintaining reliability in legacy Honeywell flame monitoring systems.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eReplacement Self-Check Shutter Assembly: Restores full self-checking functionality to compatible Honeywell UV flame detectors.\u003c\/li\u003e\n\u003cli\u003eIntegrated Coil and Shutter Mechanism: Provides synchronized electrical and mechanical motion for self-test cycling.\u003c\/li\u003e\n\u003cli\u003e120 VAC Power Operation: Designed for detectors operating on standard 120 V supply at 50\/60 Hz.\u003c\/li\u003e\n\u003cli\u003eDurable Construction: Built for continuous use in industrial burner environments.\u003c\/li\u003e\n\u003cli\u003eDirect Fit Compatibility: Installs directly into C7012E and C7012F self-checking detectors without modification.\u003c\/li\u003e\n\u003cli\u003eFactory-Calibrated Movement: Ensures accurate shutter timing to maintain flame verification integrity.\u003c\/li\u003e\n\u003cli\u003eEasy Replacement: Designed for quick field servicing with standard tools.\u003c\/li\u003e\n\u003cli\u003eReliable Operation: Maintains compliance with Honeywell Flame Safeguard system requirements.\u003c\/li\u003e\n\u003cli\u003eExtended Service Life: Precision-built coil and shutter for long-term durability under high operating temperatures.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe 190971B ensures accurate and safe flame verification, maintaining dependable performance in Honeywell self-checking flame detection systems.\u003c\/p\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":50723345105194,"sku":"190971B","price":984.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/0392\/4266\/files\/1888b5ddbb384b86a8fc34c16a6a1024.jpg?v=1761069378","url":"https:\/\/iqelectro.com\/products\/honeywell-190971b-uv-flame-detector-shutter-and-coil-assembly","provider":"IQElectro","version":"1.0","type":"link"}
