It pairs reliable ionization sensing for fast flame detection with a dedicated electrochemical CO sensor, helping alert you to two common household dangers with a single device. A built-in voice alarm clearly announces Fire, Carbon Monoxide, or Low Battery, helping occupants understand the situation at a glance.\u003c\/p\u003e\u003ch3\u003eKey benefits and features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTwo-in-one safety: smoke and CO detection in one compact unit with LED indicators and voice alerts.\u003c\/li\u003e\n\u003cli\u003ePower resilience: operates on 120V AC with two AA battery backup for protection during outages.\u003c\/li\u003e\n\u003cli\u003eClear notifications: audible alarm plus spoken warnings minimize ambiguity during emergencies.\u003c\/li\u003e\n\u003cli\u003eHush and silence: a Test-Hush feature lets you mute the alarm for approximately 9 minutes when needed.\u003c\/li\u003e\n\u003cli\u003eTamper resistance: built-in protection discourages removal of the detector from its mounting.\u003c\/li\u003e\n\u003cli\u003eInterconnected reach: up to 24 Kidde devices can be networked, within NFPA limits of initiating devices.\u003c\/li\u003e\n\u003cli\u003eStandards and warranty: UL Certified with a 10-year limited warranty, meeting UL 2034, UL 217, NFPA 72 and other safety requirements.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eInterconnection, installation, and care\u003c\/h3\u003e\u003cp\u003eFor multi-room safety, this unit can interconnect with other KN-COSM-IBA models, enabling coordinated alerts across the home. When interconnected, a single event can trigger all linked alarms, enhancing early warning across living spaces. The system supports up to 18 initiating devices (including smoke, CO, and other sensors) and up to 24 interconnected Kidde devices total, with the option to add strobes or relays as your setup grows.\u003c\/p\u003e\u003cp\u003ePractical guidance helps maximize protection: place CO and smoke alarms on every floor and near sleeping areas, keep them away from cooking or heating appliances by at least 15 feet, and consider replacement of CO sensors every 5 to 7 years to benefit from newer sensing technology. While ionization sensors detect fast-flaming fires, pairing with a photoelectric unit in separate locations is often recommended to cover different fire scenarios. UL certification and a decade-long warranty reinforce the device's durability and safety credentials.\u003c\/p\u003e\u003ch3\u003eReal-life use cases and considerations\u003c\/h3\u003e\u003cp\u003eIn daily life, you’ll notice the green LED flashing to indicate normal operation and the red LED flashing during alarms. During a power outage, the battery backup ensures continued operation, giving you time to react. The voice warnings help households with different ages or hearing abilities understand the exact danger and respond appropriately. The Hush feature is handy in kitchens or during false alarms, allowing you to restore normal monitoring without fully resetting the system.\u003c\/p\u003e\u003cp\u003eMaintenance is straightforward: test the unit regularly, observe the audible alerts, and monitor battery health. Since this is a hardwired device with a 10-year warranty, you can expect long-term protection with periodic checks and standard care routines. This model is designed to interoperate with other Kidde units, enabling scalable protection as your home or office environment evolves.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What sensors are included in the Kidde KN-COSM-IBA?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: It combines an ionization smoke sensor with a CO sensor and uses voice alerts for clear warnings.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: How does interconnection work and what is the network limit?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Up to 24 Kidde devices can be interconnected; up to 18 initiating devices, with 12 allowed for smoke alarms.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Kidde","offers":[{"title":"Default Title","offer_id":53092342431855,"sku":"B086S4Y9H5","price":152.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/0598\/3087\/files\/kidde-kn-cosm-iba-front-view.jpg?v=1778746745","url":"https:\/\/taskholt.com\/products\/kidde-kn-cosm-iba-hardwired-smoke-co-alarm-battery-backup-interconnect","provider":"TaskHolt","version":"1.0","type":"link"}
