## Long description

The Atlo ATLO-CD21MF-RF is a battery-powered, wireless carbon monoxide (CO) detector designed to monitor indoor CO levels and provide audible alerts when concentrations become dangerous. The standalone unit includes RF communication for integration with compatible wireless alarm systems, allowing central monitoring and coordinated alerts in residential and light commercial installations. Compact and simple to install, the detector is intended for continuous indoor use to support early detection of CO leaks from heating appliances, gas boilers, fireplaces, or vehicle exhaust.
Advantages
This Atlo carbon monoxide detector combines battery operation with RF connectivity so it continues to function during power outages while offering the option to link with other devices or a central alarm system. The device provides automatic CO level monitoring and an audible alarm to warn occupants of rising concentrations. The compact form factor enables flexible placement on walls or ceilings, and the wireless design reduces the need for cabling during installation. Built for residential and light commercial environments, the detector supports straightforward maintenance and battery replacement.

Homes and apartments — monitoring sleeping areas, hallways and living rooms

How to use
Install the detector according to the manufacturer’s mounting recommendations, typically on a wall or ceiling in or near sleeping areas and other frequently occupied spaces. Insert fresh batteries before first use and perform the initial power-up and any RF pairing procedure required to link the unit with a compatible wireless alarm system. Test the detector using its built-in test function after installation and at regular intervals. If the audible alarm sounds, follow established safety procedures: evacuate the area, move to fresh air, and seek emergency assistance if needed.
Usage recommendations
Place detectors at least one per floor and close to sleeping areas for effective early warning. Avoid installing directly above fuel-burning appliances or in very damp or dusty locations.
