Q.
How many CO alarms do I need in my house?
How many square metres will one CO alarm cover?
A.
We recommend you place CO alarms near the sleeping
area(s). If you have a multi-level home, you should place a CO
alarm on each level of the home. A good rule of thumb for the
number and placement of CO alarms for your particular home is
to place CO alarms near smoke alarms that have been installed to
meet current building code requirements.
Generally, one CO alarm can be adequate for 300 square metres
of living space. The most important determination for the number
of alarms needed is whether an alarm can be heard in all sleeping
areas.
Q.
Do I have to press the test button to get a CO
reading
?
A.
No. Your Nighthawk CO alarm continuously monitors the air
for carbon monoxide. An updated reading is shown on the digital
display every 30 seconds. If there is no CO present, the digital
display will show a zero. The CO alarm will alert you to the
presence of CO automatically. To test the internal components
and circuitry of your CO alarm, press the test/reset button.
