Testing with Carbon Monoxide
The unit can be tested with CO by using one of the kits that comes with CO either in a glass phial or
aerosol can. Follow the instructions on the kit. It is best if possible to inject the CO gas into the gas entry
holes, see Figure 1. When it senses the CO, it flashes the red light (as per Table B) and the display shows
the level in ppm of CO, to confirm that is detecting CO gas.
How to distinguish between CO Alarm and Smoke Alarm warnings
The CO Alarm has a distinctive on-off sound of 3 pulses, followed by a pause as compared with a typical
Smoke Alarm which has a rapid pulsing sound.
In addition, when your CO Alarm detects CO the red light will be flashing.
Testing both your CO Alarm and Smoke Alarms weekly will help you and your family to clearly distinguish
between them in an emergency.
6. MAINTAINING YOUR CARBON MONOXIDE ALARM
Clean the outside case by occasionally wiping with a clean damp cloth. Do not use any cleaning agents,
bleaches, detergents or polishes, including those in aerosol cans. Avoid spraying air fresheners, hair
spray, paint or other aerosols near the CO Alarm. Do not place air fresheners near the unit.
Use the narrow nozzle of a vacuum cleaner to remove fluff and other contamination from the cover slots
to ensure CO gas can reach the sensor - see Gas Sensor positioning shown in figure 1.
Caution: Do not paint the CO Alarm.
Remove the CO Alarm when decorating. Do not allow water or dust to contaminate the alarm.
Warning
: Do not open or tamper with the CO Alarm. There are no user serviceable parts inside This can
damage the unit.
