The Kidde KN-COP-DP-10YH is a plug-in carbon monoxide alarm designed specifically for hallways. It features a 10-year tamper-proof sealed lithium battery backup and a digital display showing live CO concentration levels. The integrated escape and night light LED provides automatic ambient illumination in dark conditions and switches to bright intensity during an alarm event to help occupants evacuate safely. The display automatically dims in low-light conditions. A peak level memory feature records the highest CO reading since last reset.
What does the escape light feature do?
The escape/night light has two modes. In normal conditions, it provides soft ambient illumination in dark hallways. During an alarm event, the LED switches to bright intensity to guide occupants toward the exit — a critical safety feature in smoke-filled or dark conditions.
Why is a hallway alarm different from a standard CO alarm?
Hallways are egress paths — the routes people use to escape from a home. The KN-COP-DP-10YH is optimized for hallway placement with its integrated escape light that brightens during an alarm to help people navigate to safety even when visibility is reduced.
