Carbon monoxide detector KIDDE K5CO — battery operated portable CO alarm, 2×AA, 85 dB, wall/ceiling/desk mount

KIDDE K5CO is a battery-operated portable carbon monoxide detector for indoor use. The device runs on two AA (1.5 V) batteries and combines optical sensing with audio-visual signalling to detect and alert occupants to elevated CO levels. Its ABS housing supports horizontal or vertical placement and allows mounting on a ceiling, wall, or use on a desk. The unit is designed for temperatures between -10 and 45 °C and relative humidity up to 90%.

Advantages

The KIDDE K5CO provides both sound and light alarms (85 dB) for clear notification, includes LED indicators and a reset function, and uses a reliable optical sensor for carbon monoxide detection. Its wireless connectivity and lightweight ABS construction make installation and repositioning straightforward, while compatibility with multiple mounting orientations increases placement flexibility.

How to use

Install two fresh AA batteries, place or mount the detector in a central indoor location following the preferred orientation (horizontal or vertical), and secure it to a ceiling, wall or desk as required. Ensure the optical sensor is unobstructed and the LED indicators are visible. Test the unit after battery installation and periodically thereafter using the device’s test/reset function to verify alarm sound and visual signalling. Replace batteries promptly when the detector indicates low battery to maintain continuous protection.

Usage recommendations

Position the detector at breathing height for best detection in occupied rooms, avoid placing it directly above stoves or in very dusty or humid locations, and follow local guidance for number and placement of CO alarms. Regularly test the unit and replace batteries at least once a year or when indicated by the device.
