## Summary description

The unit is battery powered using AAA 1.5 V cells and comes in white. Ideal for installation in homes, garages or other indoor spaces to enhance safety and provide audible warning of CO presence.

## Long description

Olympia 6121 is a battery-powered carbon monoxide (CO) detector designed to monitor indoor air for elevated CO concentrations and provide an audible warning when levels become hazardous. The compact white unit operates on AAA 1.5 V batteries and produces an 85 dB alarm to alert occupants in homes, garages and similar enclosed spaces. The device is intended to supplement household safety measures by providing early detection of CO leaks from fuel-burning appliances, heating systems or vehicle exhaust.
Advantages
The detector offers continuous passive monitoring without mains wiring, making it simple to install and relocate as needed. With an 85 dB alarm it ensures a loud audio signal that is easily heard in typical residential settings. Battery operation with standard AAA cells simplifies replacement and ensures functionality during power outages. The white housing provides a low-profile appearance suitable for ceilings or walls in a variety of indoor environments.
Suitable for
Homes and apartments
Garages and workshops

How to use
Install the detector on a wall or ceiling in a central location near sleeping areas or fuel-burning appliances but away from direct drafts, doors and windows. Insert fresh AAA 1.5 V batteries following the polarity markings in the battery compartment. Perform the device’s built-in test if available, and follow the manufacturer’s guidance for periodic testing and battery replacement. If the unit alarm sounds, evacuate the area immediately, ventilate if possible, and seek fresh air; do not ignore an audible CO alarm.
Usage recommendations
Place the detector at breathing height in sleeping areas and at least one unit per level of a dwelling where fuel-burning appliances are present. Test the detector regularly and replace batteries according to the manufacturer’s instructions. If the alarm activates, treat it as a potential danger: turn off possible sources of CO, ventilate the space, and contact qualified service personnel or emergency services if CO levels are suspected to be high.
