1. What is Carbon Monoxide?
Carbon monoxide (CO) is a highly poisonous gas that has no taste, colour or smell.
Potenal Sources of CO
• Wood-burning stoves
• Gas boilers and fires
• Gas Hobs
• Oil and coal burning appliances
• Portable gas heaters
• Blocked flues and chimneys
• Fumes from integral garages
• Barbecues
This CO alarm is no substute for proper maintenance of your
appliances.
Carbon monoxide can be produced from poorly burning appliances
or from blocked flues and chimneys.
If your alarm has sounded and you have venlated the room the CO
may have dispersed before help arrives. It is crucial that the source
of CO is determined and appropriate maintenance carried out.
Carbon monoxide is a cumulave poison meaning long-term exposure to low levels may cause
symptoms. This alarm is me-weighted – the higher the level of CO, the sooner it will alarm.

2. Further informaon
The following can lead to carbon monoxide being produced;
• Using LPG cooking appliances for space heang
• Leaving LPG appliances on overnight
To be safe, know the possible sources of CO in your home. Keep fuel burning appliances and
their chimneys and vents in good working condion. Learn the early symptoms of exposure, and
if you suspect CO poisoning, move outside to fresh air and get emergency help. Your first line of
defence is an annual inspecon and regular maintenance of your appliances. Contact a licensed
contractor or call your local ulity company for assistance.

2. Push the test buon. The alarm will beep once followed by 4 loud pulses, then a brief
pause and then 4 more pulses, ending with a single beep.
3. If you have a digital read-out alarm (model 5DCO) the LCD screen will show “---“ and then
“888” before seling at “0”
4. Check that the green LED flashes at 30 second intervals to show that the alarm has power.
This is easiest to see in a dark area, or with lights switched off.

4.Installaon Instrucons – Recommended Locaons
*It is recommended that at least one carbon monoxide alarm is installed on each level of
the home.
Recommended Locaons Not Recommended
Install the alarm more than 2 metres from
fuel burning appliances, and ideally no more
than 4 metres away
Do not install nearer than 2 metresfrom fuel
burning appliances
Away from draughts, such as doors and
windows
Do not wall-mount close to obstrucons
(e.g. behind curtains, shelving or furniture)
Within hearing distance of bedrooms* If
heang appliance is in the bedroom place
the alarm at sleeping height
Do not fit in dusty, dirty or greasy areas (e.g.
garages or workshops)
If wall-mounng, install at eye-level (approx
1.5m), and at least 30cm from adjoining walls
or ceiling
Do not wall-mount within 30cm of the ceiling
as this is a “dead air” space
If free-standing, the unit should be placed
no more than 1 metre from the ground (to
avoid permanent damage in case accidently knocked)
Avoid humid (bathrooms), cold (< 0°C) or hot
(>40°C) areas andaway from sinks

6. Using Your Alarm (for Digital unit only) – Cont’d
Peak Level Display
Press peak level buon to display the most recent CO reading between 11 – 999ppm.
This feature is useful to help you to know what levels of CO may have been detected in your

reset buon is pressed and released before releasing the peak level buon.
CO levels up to 30ppm can occur under normal non-dangerous condions. Such condions
could include nearby heavy traffic, starng a vehicle in an aached garage, starng a fire or a
nearby charcoal barbecue.

Carbon Monoxide Alarm Procedure
WARNING! Acvaonof the alarmindicates the presenceofCarbon Monoxide (CO) which cankillyou.
If alarm sounds (4 loud audible pulses followed by a pause for 5 seconds):
1) Immediately move to fresh air – outdoors or by an open door/window. Do a head count to
check that all persons are accounted for. Do not re-enter the premises nor move away from

of the alarm! If the alarm is sounding, pressing the test/reset buon will terminate the alarm. If
the CO condion that caused the alert in the first place connues, the alarm will reacvate. If
the unit alarms again within six minutes, it is sensing high levels of CO which can quickly become
a dangerous situaon.
