Operating at 120 volts AC, the unit draws power directly from household wiring and includes a 9V lithium-ion battery for backup operation during power interruptions. The alarm produces a maximum 85 decibel alert tone to signal dangerous CO levels. At 5.75 inches in diameter and 1.8 inches in projection depth, it mounts flush to a standard wall or ceiling electrical box. A tamper-resistant locking feature and sealed cover protect the unit once installed.\u003c\/p\u003e\n\u003cp\u003eThe 21006406 is suited for residential applications where hardwired CO detection is required by code. It supports interconnection with compatible alarms, allowing multiple units throughout a structure to trigger simultaneously when any single unit detects carbon monoxide. This makes it appropriate for multi-room and multi-level installations where whole-home coverage is needed. An adjustable mounting bracket and quick-connect wiring system simplify installation on new or retrofit electrical boxes. The included battery pull tab activates the backup power supply at commissioning.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e120-volt AC hardwired operation with 9V lithium-ion battery backup\u003c\/li\u003e\n  \u003cli\u003e85 dB maximum alarm output for audible CO detection alerts\u003c\/li\u003e\n  \u003cli\u003eInterconnectable with compatible alarms for whole-home CO monitoring\u003c\/li\u003e\n  \u003cli\u003eTamper-resistant locking feature and sealed cover resist unauthorized removal\u003c\/li\u003e\n  \u003cli\u003eAdjustable mounting bracket and quick-connect wiring for faster installation\u003c\/li\u003e\n  \u003cli\u003e5-year warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style hardwired replacement or new-installation carbon monoxide alarm for residential 120-volt AC electrical systems.
