## Long description

The Atlo ATLO-CD21M is a portable, battery-powered carbon monoxide (CO) detector intended for residential and small commercial spaces. The alarm continuously monitors ambient carbon monoxide levels and issues an audible alert when concentrations exceed established safety thresholds, providing a practical solution for early detection of CO buildup in homes, apartments, garages and holiday cabins.
Advantages
This compact CO alarm operates on batteries, allowing flexible placement without the need for wiring. Its continuous monitoring provides real-time response to rising carbon monoxide levels, and the audible alert ensures occupants are notified immediately. The device is lightweight and easy to relocate, making it suitable for temporary accommodation or rooms where hardwired detectors are not available. Designed for straightforward everyday use, the detector supports basic safety requirements for indoor CO detection.
Suitable for
Homes and apartments

Key specifications
Detection type: Carbon monoxide (CO)
Power source: Battery-powered for portable use
Alarm: Audible alert when CO concentration exceeds safety levels
Form factor: Compact, portable housing for easy placement
Intended locations: Indoor use in residential and small commercial environments
How to use
Install fresh batteries according to the manufacturer's instructions and place the detector in a central location at breathing height or as recommended by CO safety guidance, away from direct drafts, heating appliances and dead air spaces. Test the alarm after installation using the built-in test function if available, and replace batteries at regular intervals or when the low-battery indicator activates. If the alarm sounds, follow established safety procedures: ventilate the area, turn off potential fuel-burning appliances if safe to do so, and evacuate occupants until the source of carbon monoxide is addressed.
Usage recommendations
Position the detector near sleeping areas and on each level of the dwelling to ensure early warning during occupied periods. Avoid placing the unit directly above or beside combustion appliances to reduce false triggers and maintain regular testing and battery replacement to ensure reliable operation.
