Your new Nighthawk Battery Powered CO Alarm utilizes
sophisticated electronic components to protect you and your
family from the dangers of CO.
Unique features include a digital display capable of displaying
CO readings every 30 seconds, the highest levels of CO detected,
status of the battery life, and sensor health. Familiarise yourself
with these features:
Digital Display - Shows CO level in PPM
Your Nighthawk CO alarm continuously displays a digital
readout of the CO level in Parts Per Million (PPM). The digital
display is capable of detecting and displaying readings between
30 and 999 (PPM).
A reading of 0 PPM is expected under
normal conditions
(see figure 5).
You will become accustomed to glancing at the
display in much the same manner as you look at a
thermometer or clock. The unit will
not display a reading below 30 PPM.
See pages 19-23 for an understanding of which CO levels
are dangerous.
