It provides a red alarm LED for visual indication of alarm status and includes a key-operated test and reset function. The unit is built from brushed stainless steel, giving it durability in commercial and light industrial environments. Licensed fire alarm technicians and HVAC professionals install this device as part of a complete duct smoke detection system, typically in air handling units and HVAC ductwork where code-required remote annunciation and manual reset capability are needed.\u003c\/p\u003e\u003cp\u003eThe MS-KA\/R mounts on a standard single-gang electrical backbox, making it straightforward to integrate into existing electrical rough-in. It is intended for use in commercial HVAC applications where NFPA 72 and NFPA 90A compliance requires remote alarm indication and manual reset access at a convenient location away from the duct-mounted detector head. This is particularly common in large air handling unit installations where the primary detector is inaccessible during normal building operation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRed alarm LED provides clear visual indication of detector alarm status\u003c\/li\u003e\n\u003cli\u003eKey-operated test and reset function prevents unauthorized or accidental activation\u003c\/li\u003e\n\u003cli\u003eBrushed stainless steel construction for durability in commercial environments\u003c\/li\u003e\n\u003cli\u003eMounts on a standard single-gang electrical backbox for easy integration\u003c\/li\u003e\n\u003cli\u003eDesigned for use with Air Products and Controls duct smoke detectors\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Air Products and Controls Duct Smoke Detectors to provide remote alarm LED indication and remote test and reset functions.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed fire alarm technician or qualified electrician in accordance with NFPA 72 and applicable local codes. Power down and de-energize the fire alarm control panel circuit before wiring the remote accessory. Mount on a standard single-gang electrical backbox at a location accessible to building personnel for routine test and reset operations. Verify system operation with a functional test after installation per the detector manufacturer instructions.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brushed stainless steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting\u003c\/strong\u003e: Standard single-gang electrical backbox\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndicator\u003c\/strong\u003e: Red alarm LED\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControl Function\u003c\/strong\u003e: Key-operated test and reset\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SYSTEM SENSOR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MS-KA\/R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AIR PRODUCTS AND CONTROLS","offers":[{"title":"Default Title","offer_id":51468629836082,"sku":"MS-KA\/R","price":66.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/MS-ka_r_632946f8-56cd-4959-b215-1217ebf863af.png?v=1783919358","url":"https:\/\/voomisupply.com\/products\/system-sensor-ms-ka-r-remote-accessory-duct-smoke-detector","provider":"Voomi Supply","version":"1.0","type":"link"}
