Frequently Asked Questions - KN-COB-DP2CA KIDDE
Where should I install the KN-COB-DP2CA CO detector?
Install it outside each sleeping area and on every level of your home. Mount it on a wall at least 5 feet above the floor or on the ceiling, away from vents and windows.
How do I test the alarm?
Press and hold the Test/Hush button until the alarm sounds. The digital display will show '---' during test. Release the button to stop.
What does the Hush feature do?
The Hush button temporarily silences the alarm for about 9 minutes if you are experiencing a known false alarm (e.g., from cooking). The unit will automatically reset.
What does the digital display show?
It shows the current CO concentration in parts per million (ppm). When CO is detected, it displays the peak level it recorded since last reset.
How often should I replace the battery?
Replace the 9V backup battery at least once a year, or when the unit chirps indicating low battery. The detector also has a 10-year end-of-life warning.
Why does my CO detector chirp intermittently?
Chirping typically indicates a low backup battery, end-of-life, or a malfunction. Replace the battery first; if chirping continues, the unit may need replacement.
Can I interconnect multiple Kidde detectors?
Yes, the KN-COB-DP2CA can interconnect with up to 12 Kidde smoke or CO alarms. Use the interconnect wire (yellow) for hardwired connection.
What should I do if the alarm sounds continuously?
If the alarm sounds 4 beeps followed by a pause, this indicates dangerous CO levels. Immediately evacuate, call emergency services, and do not re-enter until cleared.
How do I clean and maintain the detector?
Vacuum the detector cover monthly using a soft brush attachment to remove dust. Do not use water or cleaners. Test it weekly.
What is the lifespan of the detector?
The KN-COB-DP2CA has a 10-year lifespan from the date of installation. The unit will chirp and display 'End' to indicate it needs replacement.
