The relay base provides a switched output that activates when the paired detector enters alarm, allowing the system to trigger auxiliary devices such as fans, dampers, or notification appliances. It is sold as a single unit and carries both UL and ULC listings, confirming it meets North American standards for fire alarm equipment. Licensed fire alarm technicians and low-voltage electricians are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThe KC2-RB4 relay base is suited for commercial and residential fire alarm installations where a localized switched output is needed at the detector location. It is categorized as a fire alarm accessory and is intended for 2-wire system configurations. Typical applications include HVAC shutdown, door holder release, and auxiliary notification control tied directly to a single detector zone.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-wire relay base configuration for compatible detector heads\u003c\/li\u003e\n  \u003cli\u003eSwitched relay output enables control of auxiliary devices at the detector level\u003c\/li\u003e\n  \u003cli\u003eUL and ULC listed for compliance with North American fire alarm standards\u003c\/li\u003e\n  \u003cli\u003eSingle-unit packaging suitable for individual zone or device installations\u003c\/li\u003e\n  \u003cli\u003eFire alarm accessory category for use in structured detection systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or expansion component for 2-wire fire alarm detector base applications.

De-energize and isolate the fire alarm control panel circuit before removing or installing any detector base. Verify that the connected detector head model is rated for use with a relay base before completing the circuit. Do not restore system power until all wiring connections have been inspected and the detector head is fully seated in the base.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWiring Configuration\u003c\/strong\u003e: 2-wire\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Type\u003c\/strong\u003e: Relay base\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eListings\u003c\/strong\u003e: UL, ULC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each (1 per package)\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: KC2-RB4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EDWARDS SIGNALING","offers":[{"title":"Default Title","offer_id":51687346929970,"sku":"KC2-RB4","price":65.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/be34e714362d419dd25d9aca5fa5310b.jpg?v=1788233075","url":"https:\/\/voomisupply.com\/products\/kidde-edwards-kc2-rb4-2-wire-relay-base-ul-ulc","provider":"Voomi Supply","version":"1.0","type":"link"}
