Carbon Monoxide Detector

The Kidde KS900 is a battery-operated carbon monoxide (CO) alarm and uses the patented Nighthawk electrochemical CO sensor to help protect you and your family from the dangers of CO.

This Kidde KS900 is easy to install, and when the Kidde KS900 is operating properly and hazardous CO levels are not detected, its green LED flashes every 30 seconds. In a CO emergency, the red LED pulses and an 85 dB horn sounds at specific intervals until the CO threat is eliminated.

Because this unit is powered by AA batteries, the Kidde KS900 is able to provide continuous monitoring of CO levels, even during power outages. The Kidde KS900 also has an alarm that tells you when the batteries need to be replaced. For peace of mind, a test / reset button allows you to test that alarm is functioning properly.

A peak-level memory keeps track of the maximum CO level detected between resets. The KS900 is covered with a 7-year manufacturers limited warranty and replacement is recommended after seven years.
