What To Do If The Alarm Sounds

Never restart the source of a CO problem until it has been fixed. NEVER IGNORE THE ALARM!

The CO sensor meets the alarm response time requirements of UL standard 2034. Standard alarm times are as follows:

At 70 PPM, the unit must alarm within 60-240 minutes. At 150 PPM, the unit must alarm within 10-50 minutes. At 400 PPM, the unit must alarm within 4-15 minutes.

This carbon monoxide alarm is designed to detect carbon monoxide gas from ANY source of combus- tion. It is NOT designed to detect any other gas.

Fire Departments, most utility companies and HVAC contractors will perform CO inspections, some may charge for this service. It’s advisable to inquire about any applicable fees prior to having the service performed. Kidde will not pay for, or reimburse, the owner or user of this product, for any repair or dispatch calls related to the alarm sounding.

Battery Replacement

If any form of battery failure is detected the red LED light will flash and the unit will “chirp” one time, followed by the warning message “LOW BATTERY”. This cycle will occur once every minute for the first hour. After the first hour, the red LED light will continue flashing accompanied by the chirp only sound every 60 seconds. The voice message “LOW BATTERY” will sound once every fifteen minutes during the chirp only cycle, and will continue for at least seven days.

If the red LED light flashes along with a chirp every 30 seconds, and is not followed by the voice message “LOW BATTERY” as described above, your unit has malfunctioned. Call our toll free Consumer Hotline at 1- 800-880-6788 for instructions on how to return the unit.
