This reflected light reaches the receiving element, triggering the alarm response.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eFeatures\u003cbr\u003e\u003c\/strong\u003e\u003cbr\u003e• Highly stable operation, RF\/transient protection.\u003cbr\u003e• One built-in power\/sensitivity supervision\/alarm LED.\u003cbr\u003e• Computer-designed non-directional smoke chamber.\u003cbr\u003e• 360° view of detector status LED.\u003cbr\u003e\u003c\/p\u003e","brand":"Bosch","offers":[{"title":"Default Title","offer_id":44453876990106,"sku":"FCD-350-DH","price":61.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0213\/7895\/7412\/files\/166_229161a3-9700-4a0a-baa2-c357988113ad.png?v=1762990908","url":"https:\/\/nassaunationalcable.com\/products\/duct-photo-smoke-detector-head-fcd-350-dh","provider":"NassauNationalCable","version":"1.0","type":"link"}
