7.0 IMPORTANT: WHAT YOUR CO
ALARM CAN AND CANNOT DO
This CO alarm is designed for use within a
single residential living unit, recreational
vehicle or unconditioned areas. It is
designed to detect carbon monoxide (CO)
entering its sensing chamber. It does not
sense combustible gas (such as natural gas,
propane or (butane), heat, smoke or flames.
When properly located, installed, and
maintained, this CO alarm is designed to
provide early warning of developing
poisonous CO conditions at a reasonable
cost. This alarm monitors the air, and when
it senses CO, it activates its built-in alarm. It
can provide precious time for you and your
family to escape from your residence before
CO can seriously injure or kill. However,
such an early warning is possible only if the
alarm is located, installed, and maintained
as specified in the Owner’s Manual
8.0 INSTALLING THE COSTAR®9RV
One of the most important considerations in
any CO alarm system is the location of the
alarms. Statistics of the National Fire
Protection Association (NFPA) show that
most of the fatal CO occurrences happen at
night while people are sleeping and/or
while they are in the garage. Early warning
of CO is best achieved by the correct
installation of CO alarms.
8.1 RESIDENTIAL INSTALLATION
RECOMMENDATIONS
If bedroom doors are usually closed at
night, alarms should be placed in each
bedroom as well as in the common hallway
between them. CO alarms may not sense
CO on a different level of a residence or
building. For example, a second floor alarm
may not sense a CO leak on the first floor or
