It operates on 120V AC power with a 9V battery backup to maintain protection during power outages. The unit uses an electrochemical CO sensor rated for a 10-year service life and incorporates intelligent sensing technology to reduce nuisance alarms. A licensed electrician typically performs the hardwired installation, which connects to existing household wiring through a quick plug-in power connector for straightforward setup and future maintenance access.\u003c\/p\u003e\n\u003cp\u003eThis alarm is suited for residential new construction and retrofit applications where local building codes mandate carbon monoxide detection. It is typically installed in sleeping areas, hallways, and other locations specified by the International Residential Code or applicable local amendments. The quick plug-in connector reduces installation time and simplifies unit replacement when the sensor reaches end of life. A latching alarm indicator allows technicians to confirm a CO event occurred even after the alarm has been silenced, which aids in post-event diagnosis.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eElectrochemical CO sensor with a 10-year rated service life\u003c\/li\u003e\n  \u003cli\u003e120V AC hardwired operation with 9V battery backup for continuous protection during outages\u003c\/li\u003e\n  \u003cli\u003eIntelligent sensing technology limits nuisance alarms\u003c\/li\u003e\n  \u003cli\u003eLatching alarm indicator retains event history after silence\u003c\/li\u003e\n  \u003cli\u003eSingle button test and silence operation with two silence feature modes\u003c\/li\u003e\n  \u003cli\u003eEnd-of-life signal alerts when sensor replacement is needed\u003c\/li\u003e\n  \u003cli\u003eQuick plug-in power connector for easy installation and maintenance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style hardwired carbon monoxide alarm for residential applications requiring 120V AC\/DC CO detection with battery backup.
