## Long description

Key specifications

How to use
Install the AWTools AW23821 at breathing height in the rooms to be monitored, avoiding places with excessive humidity, direct drafts or very dusty locations. Insert two fresh AA 1.5V batteries following the polarity markings and secure the battery cover. Test the alarm after installation using the manufacturer’s test button (if available) to confirm the audible signal. Replace batteries according to the product’s low-battery indication or at regular intervals to ensure continuous operation. If the alarm sounds, evacuate occupants, ventilate the area and seek assistance to identify and rectify the CO source.
Usage recommendations
Place alarms in sleeping areas and on each level of the building, keep units at least several feet from fuel-burning appliances to prevent false triggers from normal appliance emissions, and perform periodic tests and battery replacements to maintain reliable detection.
