Part One – Your Nighthawk CO Alarm
About Your CO Alarm
The number one feature that sets Nighthawk apart from other
alarms is its unique digital display that gives you a continuos read-
out of CO levels from 30-999 parts per million. The digital
display serves as an early warning of CO presence. Additionally,
the digital display gives you added time to find the source of the
CO and correct the problem, limiting the risk of unrecognized long
term exposure. Of course, the loud 85 decibel alarm warns of
higher levels.
Nighthawk is the only CO alarm that gives you the choice of a
direct-plug, a 6' power cord or table top unit all in one. Depending
on how or where you wish to mount your unit, you can get exact-
ly what you need for a perfect application. These are just a few
reasons over 4.5 million families have chosen Nighthawk over
every other brand for this kind of life-saving protection.
