900-0284CA


10 years of worry-free carbon monoxide protection

  • CREE® LED Nightlight – Nightlight with adjustable brightness levels auto-activates during low light conditions, when connected to AC power. During alarm mode, the nightlight will brightly illuminate and can help people exit rooms during alarm situations, even during a power outage.
  • Digital Display – Shows CO level in PPM (parts per million). No buttons to push! Continuous digital readout gives you peace of mind at-a-glance. LEDs provide clear daytime visibility that automatically dims in dark conditions.
  • AC Plug-in Operated – Easy to install – just plug into an AC wall outlet.
  • 10 Year Sealed Battery Backup – Provides protection during power outages and does not need replacement during life of the alarm.
  • Peak Level Memory – Displays the highest CO concentration measured since the last reset.
  • Test / Hush Button – Tests the unit for proper operation. Resets the carbon monoxide alarm.

Plug-in (AC) with Battery Backup

The Kidde 900-0284CA (Model: KN-COP-DP-10YHCA) is a 120 V AC powered, plug-in carbon monoxide alarm with sealed lithium battery backup and a digital display. The 900-0284CA is an easy to install unit that provides reliable protection against the dangers of carbon monoxide. The 10-year* sealed battery offers protection during power outages, prevents unwarranted removal of the battery, and eliminates the need for annual battery replacement.

The CREE® LED Nightlight turns on in low-light conditions and can be adjusted to ten different levels by pushing the peak level button, or turning off if needed. The ambient light sensor will automatically turn the night light on or off, depending on ambient light conditions, when connected to AC power. 

The nightlight will brightly illuminate during alarm mode, helping those present to exit during dark conditions and when electrical power outages occur.

The digital display feature adds an advanced level of protection showing CO levels in PPM allowing you to see if levels change. The display will automatically adjust brightness level to adapt to ambient light conditions, giving a brighter display in lighted environments, while dimming to provide a visible, but softer contrast in dark conditions. The display deactivates when AC power is removed to conserve battery life.

The 900-0284CA is suitable for all living areas and has a 10-year limited warranty.
