Photoelectric smoke detectors use light-scattering technology to sense the presence of smoke particles, making them well suited for detecting slow, smoldering fires. This unit falls within the fire control accessories category and is installed by licensed fire alarm technicians or qualified security system contractors working on conventional detection circuits.\u003c\/p\u003e\u003cp\u003eThe FW-4-H-E is intended for use in conventional fire alarm panel installations where zone-based smoke detection is required. It is appropriate for residential and light commercial applications where a conventional wired detection circuit is already in place. Installation typically involves wiring the detector into an existing supervised detection loop connected to a compatible fire alarm control panel.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePhotoelectric detection technology for effective response to slow-burning, smoldering fires\u003c\/li\u003e\n\u003cli\u003eConventional wiring configuration for compatibility with zone-based fire alarm systems\u003c\/li\u003e\n\u003cli\u003eSold as an individual unit, allowing single-point replacement or system expansion\u003c\/li\u003e\n\u003cli\u003eDesigned as a fire control accessory for integration into supervised detection circuits\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or addition for conventional fire alarm control panel systems requiring photoelectric smoke detection on a supervised zone circuit.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed fire alarm technician in accordance with NFPA 72 and all applicable local codes. Before servicing or replacing any detector, de-energize the fire alarm control panel circuit and follow the panel manufacturer's lockout procedure. Verify loop supervision continuity after installation and conduct a functional smoke test before returning the system to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDetection Type\u003c\/strong\u003e: Photoelectric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory\u003c\/strong\u003e: Fire Control Accessories\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity Per Pack\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NAPCO SECURITY TECHNOLOGIES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: FW-4-H-E\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NAPCO SECURITY TECHNOLOGIES","offers":[{"title":"Default Title","offer_id":67917585449266,"sku":"FW-4-H-E","price":243.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6923d15c44cb92cd5f11d13108e5e87d.jpg?v=1791264086","url":"https:\/\/voomisupply.com\/products\/napco-fw-4-h-e-photoelectric-smoke-detector","provider":"Voomi Supply","version":"1.0","type":"link"}
