It combines audible and visible alerting in a single device, producing a 520 Hz tone output at 70 volts and delivering strobe output in the 95 to 177 candela range. This combination makes it suitable for high-ambient-noise environments where both audible and visual notification are required. Licensed fire alarm installers and low-voltage systems technicians are the primary trades who specify and install this device as part of an addressable or conventional fire alarm system.\u003c\/p\u003e\n\u003cp\u003eThis ceiling speaker strobe is intended for commercial and institutional applications where a single notification appliance must meet both audible and strobe requirements per fire code. Typical installations include office buildings, schools, healthcare facilities, and other occupancies subject to NFPA 72 notification appliance requirements. The 70-volt audio line configuration integrates with standard 70V distributed audio fire alarm panels. The 95 to 177 candela strobe output range allows for flexible placement to meet photometric coverage requirements in larger or open ceiling spaces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeiling-mount design combines speaker and strobe in one notification appliance\u003c\/li\u003e\n  \u003cli\u003e70-volt audio line operation for compatibility with standard fire alarm panel audio outputs\u003c\/li\u003e\n  \u003cli\u003e520 Hz tone output meets low-frequency alarm signal requirements\u003c\/li\u003e\n  \u003cli\u003eStrobe output range of 95 to 177 candela for flexible code-compliant placement\u003c\/li\u003e\n  \u003cli\u003eSingle-device installation reduces conduit runs and junction box count\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style ceiling notification appliance for use with 70-volt fire alarm audio systems requiring combined speaker and strobe functionality.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed fire alarm technician in accordance with NFPA 72 and all applicable local codes. De-energize the fire alarm control panel and silence the audio circuit before making any wiring connections. Verify strobe candela placement meets the photometric spacing requirements defined by the authority having jurisdiction before final mounting. Do not apply power until all connections are inspected and the panel is configured for the correct audio output voltage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStrobe Output\u003c\/strong\u003e: 95-177 candela\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAudio Line Voltage\u003c\/strong\u003e: 70 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTone Frequency\u003c\/strong\u003e: 520 Hz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting\u003c\/strong\u003e: Ceiling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KIDDE EDWARDS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: GCHFWF-S7VMCH\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EDWARDS SIGNALING","offers":[{"title":"Default Title","offer_id":51685882593586,"sku":"GCHFWF-S7VMCH","price":233.34,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e9336e50c0d7a13aeddc5f1c4c7449f3.jpg?v=1788220219","url":"https:\/\/voomisupply.com\/products\/kidde-edwards-gchfwf-s7vmch-ceiling-speaker-strobe-70v-520hz","provider":"Voomi Supply","version":"1.0","type":"link"}
