The KN-COB-IC draws power directly from the building's 120V AC electrical system and features full interconnect capability, allowing it to communicate with other compatible Kidde hardwired alarms across a facility. When CO is detected by any single unit in the network, every connected alarm activates simultaneously — a critical feature for ensuring rapid occupant notification throughout large or multi-story structures. Certified to UL 2034, the KN-COB-IC is a foundational building block for comprehensive CO safety programs.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower:\u003c\/strong\u003e 120V AC hardwired, no battery needed for primary operation\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterconnect:\u003c\/strong\u003e Yes — compatible with Kidde hardwired alarm ecosystem\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertification:\u003c\/strong\u003e UL 2034 listed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSensor:\u003c\/strong\u003e Electrochemical CO detection\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSKU:\u003c\/strong\u003e KN-COB-IC\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhy Choose the Kidde KN-COB-IC?\u003c\/h2\u003e\n\u003cp\u003eThe KN-COB-IC delivers the core requirements for commercial CO protection: hardwired reliability, interconnect networking, and UL 2034 certification — all in a streamlined, cost-effective form factor. For facilities managers who need proven CO detection without the ongoing maintenance burden of battery replacement, the KN-COB-IC's AC hardwired design provides continuous, uninterrupted monitoring as long as the building has power. This makes it especially well-suited for occupied facilities like schools, assisted living centers, hotels, and offices where lapses in CO protection carry serious liability and safety consequences.\u003c\/p\u003e\n\u003cp\u003eThe interconnect capability distinguishes the KN-COB-IC from standalone battery units. In networked installations, a CO event in any location — a boiler room, parking garage, or utility closet — instantly triggers alarms throughout the connected system, giving building occupants maximum warning time regardless of where the CO source is located. For safety directors and building engineers, this means fewer reliance on human notification chains and a more robust, automated emergency response architecture. The KN-COB-IC is designed for straightforward installation by licensed electricians, compatible with standard junction boxes, and integrates seamlessly into new construction or retrofit projects.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e120V AC hardwired power for continuous, maintenance-light CO monitoring\u003c\/li\u003e\n  \u003cli\u003eFull interconnect capability with compatible Kidde hardwired alarm systems\u003c\/li\u003e\n  \u003cli\u003eSimultaneous alarm activation across all networked units when CO is detected\u003c\/li\u003e\n  \u003cli\u003eUL 2034 listed — compliant with U.S. commercial and residential CO alarm standards\u003c\/li\u003e\n  \u003cli\u003eElectrochemical sensor technology for accurate, long-term CO detection\u003c\/li\u003e\n  \u003cli\u003eTest\/reset button for scheduled safety inspections and compliance documentation\u003c\/li\u003e\n  \u003cli\u003eLow-profile housing designed for wall mounting in any occupied space\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard electrical junction boxes for easy installation\u003c\/li\u003e\n  \u003cli\u003e85 dB alarm for clear audible alert even in noisy environments\u003c\/li\u003e\n  \u003cli\u003eMeets NFPA 720 and International Fire Code (IFC) requirements\u003c\/li\u003e\n  \u003cli\u003eSuitable for new construction and retrofit applications\u003c\/li\u003e\n  \u003cli\u003eBacked by Kidde, a Carrier company with decades of fire and CO safety expertise\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eReal-World Benefits\u003c\/h3\u003e\n\u003cp\u003eFor safety managers overseeing multi-story or campus-style facilities, the KN-COB-IC's interconnect feature transforms a collection of standalone CO alarms into a cohesive building safety network. When a single unit detects CO in any mechanical room or utility space, every alarm in the connected system — across floors, wings, or buildings — alerts simultaneously. This provides occupants maximum response time and reduces the risk of CO exposure in areas distant from the detection source.\u003c\/p\u003e\n\u003cp\u003eFacilities teams appreciate the reduced maintenance footprint of AC hardwired alarms. Without batteries to check, replace, or track, ongoing compliance is simpler and more reliable. During annual fire safety inspections, the KN-COB-IC's test\/reset button allows quick verification of alarm function, supporting documentation requirements for OSHA, local fire marshals, and insurance carriers. For procurement teams managing large installations, the KN-COB-IC's compatibility with the broader Kidde hardwired ecosystem means consistent parts, installation procedures, and vendor relationships across the entire property portfolio.\u003c\/p\u003e\n\u003cp\u003eThe KN-COB-IC is also a cost-efficient choice for organizations that need proven CO detection without advanced features like digital PPM displays. By focusing on core hardwired reliability and interconnect capability, it provides commercial-grade protection at a practical price point — ideal for bulk deployments across school districts, hotel chains, or multi-family housing operators.\u003c\/p\u003e\n\n\u003ch3\u003eApplications and Ideal Use Cases\u003c\/h3\u003e\n\u003cp\u003eThe Kidde KN-COB-IC is ideal for any permanent commercial or institutional installation requiring code-compliant CO detection. Key applications include elementary and secondary schools (mandated by many state codes), colleges and universities, hotels and extended-stay properties, multi-family residential buildings, office buildings with combustion-based HVAC systems, healthcare and assisted living facilities, government and municipal buildings, retail spaces with attached loading or service areas, and light industrial facilities with combustion equipment.
