INSTALLATION
WHERE TO INSTALL CO ALARMS
The National Fire Protection Association (NFPA) recommends that a CO Alarm
s
hould be centrally located outside of each separate sleeping area in the
i
mmediate vicinity of the bedrooms. For added protection, install additional
CO Alarms in each separate bedroom, and on every level of your home.
If your bedroom hallway is longer than 40 feet (12 meters), install a CO Alarm
at BOTH ends of the hallway
.
In a Single-level Home:
• Install at least one CO Alarm near or within each separate sleeping area.
• For added protection, install an additional CO Alarm at least 20 feet
(6 meters) away from the furnace or fuel burning heat source.
In a Multi-level Home:
•
Install at least one CO Alarm near or within each separate sleeping area.
•
For added protection, install at least one CO Alarm on each level of the
home. If you have a basement, install that CO Alarm at the top of the
basement stairs.
• For added protection, install an additional CO Alarm at least 20 feet
(6 meters) away from the furnace or fuel burning heat source.
This unit should receive continuous electrical power. (The battery is
meant for emergency back-up only). Choose an outlet where it can’t be
accidentally unplugged or switched of
f by childr
en. Keep small children
away from the unit. Teach them not to play with it or unplug it. Explain
what the alar
ms mean.
