The ADEMCO INC. 1046862 is a battery-powered combination smoke and carbon monoxide alarm designed for residential installation. It operates on battery power, eliminating the need for hardwiring and simplifying placement in a wide range of room configurations. The unit detects both smoke and CO in a single device, reducing the number of individual alarms required to meet code in a dwelling. This alarm is sold in a package quantity of four units, making it well suited for whole-home installations or multi-unit service calls handled by licensed contractors and alarm technicians.
This combo alarm is intended for residential use in areas where both smoke and carbon monoxide detection are required by local building or fire codes. Battery operation makes it practical for retrofit installs, rental property upgrades, and new construction where wiring runs are not yet in place. The four-pack configuration is particularly useful for service contractors stocking inventory for scheduled installs or property management work orders.
Designed as a standalone battery-operated combination smoke and carbon monoxide alarm suitable for standard residential ceiling or wall mounting locations.
Installation is typically performed by a licensed electrician, HVAC technician, or general contractor following local fire and building codes. No power shutoff is required for battery-only units, but installers should confirm local code requirements for alarm placement height and room coverage before mounting. Follow the manufacturer instructions included with the unit for mounting hardware use and battery insertion sequence. Do not install in areas with high humidity, extreme temperatures, or excessive dust that may affect sensor performance.
