Carbon Monoxide Safety Carbon Monoxide Alarm Procedure WARNING: Activation of the CO Alarm indicates the presence of Carbon Monoxide (CO) which can kill you. 1) Operate the Test/Reset button; 2) Call your emergency services (Fire Department or 911); PHONE NUMBER 3) Immediately move to fresh air - outdoors.
Carbon Monoxide Safety Replacement of Alarm Seven years after initial power up, this unit will "chirp" every 30 seconds to indicate that it is time to replace the alarm. A label has been provided that has “Replace by:” printed on it. Write the replace-by date on the label and affix it to the front of the alarm so it is visible after mounting.
Because carbon monoxide is a cumulative poison, long- term exposures to low levels may cause symptoms, as well as short-term exposures to high levels. This Kidde unit has a time-weighted alarm - the higher the level of carbon monoxide present, the sooner the alarm will be triggered.
Carbon Monoxide Safety Instruct children never to touch, unplug or otherwise interfere with the alarm. Warn children of the dangers of CO poisoning. CO alarms are not a substitute for property, disability, life or other insurance of any kind. Appropriate insurance coverage is your responsibility.

Excessive spillage or reverse venting of fuel-burning appliances caused by outdoor ambient conditions such as: • Wind direction and/or velocity, including high gusts of wind, heavy air in the vent pipes (cold/humid air with extended periods between cycles).
