(4) CO Alarms don’t last indefinitely. CO Alarms are sophisticated electronic devices
with many parts. Although the Alarm and its component parts have undergone
stringent tests, and are designed to be very reliable, it is possible that parts can fail.
Therefore, you should test your CO Alarm weekly. The CO Alarm must be replaced
after 10 years of operation.
(5) CO Alarms are not a substitute for life insurance. House-holders are responsible
for their own insurance. The CO Alarm warns of increasing CO levels, but we do not
guarantee that this will protect everyone from CO poisoning.
(6) CO Alarms are not suitable as early warning Smoke Alarms. Some fires produce
Carbon Monoxide, but the response characteristics of these CO Alarms are such that
they would not give sufficient warning of fire. Smoke Alarms must be fitted to give
early warning of fire.
(7) The CO Alarm does not detect the presence of natural gas (methane), bottled gas
(propane, butane) or other combustible gases. Fit combustion Gas Alarms to detect
these. Note: Carbon Monoxide Alarms, with electrochemical sensors have a cross
sensitivity to hydrogen. This means that they can alarm due to sensing hydrogen being
produced by batteries being incorrectly charged such as on boats or with battery back-
up systems such as those used with alternative energy systems. The unit will alarm
with 500 ppm H
2 after between 10 and 40 minutes exposure.
This CO Alarm is intended for residential use. It is not intended for the use in
industrial applications where Occupational Safety and Health Administration (OSHA)
requirements for carbon monoxide detectors must be met.
This carbon monoxide alarming device is designed to detect carbon monoxide gas
from ANY source of combustion. It is NOT designed to detect smoke, fire, or any
other gases.
