Kidde Nighthawk Plug-in AC/DC Carbon Monoxide Alarm Detector with Digital Display KN-COPP-3
Peak Level Button – Displays the peak CO level recorded by the alarm since it was last reset or unplugged
Test Button Functions – Tests the unit for proper operation and resets the Carbon Monoxide alarm
LED Operation – Blinking dot in lower right corner of display denotes normal operation
Ten years after the initial power up, this alarm will “beep” two times every 30 seconds to indicate that it is time to replace the alarm.
NOTE: This CO alarm is not battery operated. However, these alarms are equipped with 9 volt battery backup – the 9 volt battery is to supply short term back-up during a power outage.
Bought it at Home Depot a year ago at $43, still a pretty new item. Moving sale. Asking for $22. Pick-up or cash only.
