The Kidde KN-COP-DP-B is an AC-powered plug-in carbon monoxide alarm with battery backup and digital display. The display automatically dims in low-light conditions for bedroom comfort. A Peak Level Button recalls the peak CO level recorded since last reset. An End of Life Alarm alerts users to replace the CO alarm after 10 years of operation — it can be temporarily silenced for convenience. Battery backup ensures continuous CO monitoring during power outages.
Does the KN-COP-DP-B work during a power outage?
Yes. The battery backup maintains CO detection if AC power is interrupted. The batteries provide protection until power is restored. This is important because CO from fuel-burning appliances can still be generated during power outages when using backup generators or heating equipment.
What is the End of Life Alarm on the KN-COP-DP-B?
After 10 years of operation, the alarm will chirp to signal that the unit has reached the end of its service life and should be replaced. This chirp can be temporarily silenced. CO alarm sensors degrade over time, so replacement after 10 years is recommended even if the alarm appears to be functioning.
