At a Glance


Offering a small, sleek design that's suitable for all living areas, the Nighthawk KN-COPP-B-LP provides you and your family with a loud warning signal against the dangers of elevated carbon monoxide levels. You'll get continuous monitoring of CO levels, even during power outages when AC-only units are not providing protection. The digital display adds an advanced level of protection, showing CO levels in PPM (parts per million) and allowing you to see if levels change. The backlighting helps you read the display in the dark, and it also appears during the peak level cycle. The unit also has a peak level memory, which displays the highest CO concentration measured since the last reset.

It features two color LEDs for at-a-glance status updates. The green LED flashes once every 30 seconds to indicate the alarm is working properly. A red LED will pulse to indicate that carbon monoxide has been detected. When the unit detects carbon monoxide, the alarm sounds four short beeps (rated at 85 decibels at 10 feet), followed by five seconds of silence, and then followed by another set of four short beeps. The unit measures 3 inches by 5 inches by 1.5 inches.

The KN-COPP-B-LP includes multiple mounting options, allowing installation on a wall or a tabletop. It has a seven-year operating life (with matching seven-year limited warranty), providing 40 percent longer protection than other CO alarms. It's powered by 3 AA batteries (included).
