The detector activates when ambient temperature reaches a fixed threshold, making it suitable for environments where smoke detectors would false-alarm due to dust, steam or cooking fumes.\u003c\/p\u003e\n\u003cp\u003eDesigned for kitchens, garages, boiler rooms, dusty workshops and commercial catering spaces, the detector operates on 9-30V DC conventional fire alarm panels and carries Class A2S rating. The included relay base allows the detector head to be removed for cleaning or replacement without rewiring the base, and provides relay contact outputs for auxiliary functions like duct damper closure or local alarm sounders.\u003c\/p\u003e\n\u003cp\u003eThe white thermoplastic housing contains a bimetallic element that closes a contact when the fixed temperature threshold is reached, triggering the alarm zone on the connected fire panel. The detector sits flush to the ceiling with a low-profile 100mm diameter footprint and is rated IP30 for indoor use. EN54-5 certification confirms compliance with European fire safety standards for heat-sensitive fire detectors.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Net Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.15\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.17\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e6.8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Length (mm)\u003c\/td\u003e\n\u003ctd\u003e260\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Width (mm)\u003c\/td\u003e\n\u003ctd\u003e440\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Height (mm)\u003c\/td\u003e\n\u003ctd\u003e240\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/products_FHD212_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/manual_FHD212.pdf\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat temperature does the detector activate at?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe FHD212 is a fixed temperature detector with a Class A2S rating. The exact activation temperature is specified in the datasheet, typically around 54-58°C for standard A2S detectors.

They respond only to temperature rise, not to airborne particles.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat fire alarm panels is this compatible with?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe detector operates on conventional fire alarm panels with 9-30V DC output. It connects via two-wire conventional zone wiring and is not compatible with analogue addressable systems.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan the detector head be removed without rewiring?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. The detector head twists off the relay base, allowing cleaning, inspection or head replacement without disconnecting wiring at the base. This simplifies maintenance in multi-detector installations.\u003c\/p\u003e","brand":"ESP","offers":[{"title":"Default Title","offer_id":45294087995659,"sku":"FHD212","price":12.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/FHD212_61e2b6d4-212a-4611-ae4e-d2fdcf90cf3f.jpg?v=1714667929","url":"https:\/\/niori.co.uk\/products\/magfire-12v-fixed-temperature-heat-detector-with-relay-base-en54-5","provider":"Niori","version":"1.0","type":"link"}
