2. Carbon Monoxide – The Silent Killer
2.1 What is Carbon Monoxide ?
Many people are killed each year, and many more suffer ill health from Carbon

toxic gas. It is produced by appliances and vehicles burning fuels, such as coal, oil,
natural/bottled gas, paraffin, wood, petrol, diesel, charcoal etc. CO is absorbed by
red blood cells in the lungs in preference to oxygen - this results in rapid damage
to the heart and brain from oxygen starvation.
High levels of CO in a house can be caused by:

2.2 What happens when your CO Alarm detects Carbon Monoxide ?
When the Alarm detects potentially dangerous levels of CO, it flashes the red alarm

below shows how the CO Alarm reacts to different levels of CO gas and exposure
time. At higher levels of CO the Alarm turns on sooner. The rate of flashing of the
red light indicates the level of CO. If your CO Alarm sounds follow the instructions
in section 6. NEVER IGNORE THE ALARM !

triggered by CO coming for example, from cooking with gas, from car engines or
from nearby barbecues. This is usually not a concern, unless the pre-alarm signal
persists until the Alarm sounds and the CO source is unknown.

NOTE: The CO Alarm may sound if cigarette smoke is blown into it, or aerosols

2.5 CO Alarm Memory
The CO Alarm memory is an important feature of the CO Alarm where even if the
house is unoccupied during an alarm condition it warns the homeowner that the CO
Alarm has previously detected CO gas and been in alarm. The memory feature has
two operation modes:
- memory indication for 24 hour period after alarm.
- memory recall on demand
24 hour memory indicators: After alarm, the RED light will flash at different rates

Memory recall on demand: To review the memory status after initial 24 hours,
press and hold the test button, the red led will flash in accordance to Table C.
Display models will show the peak level of CO measured.

Please note that the memory will also be reset when the CO Alarm is switched off.
3. Where to place CO Alarms
3.1 Ideally a Carbon Monoxide Alarm should be installed in:
- Every room containing a fuel burning appliance, and
- Remote rooms where occupants spend a considerable amount of time
- Every bedroom
However if the number of Carbon Monoxide Alarms to be fitted is limited, the
IROORZLQJSRLQWVVKRXOGEHFRQVLGHUHGZKHQGHFLGLQJZKHUHEHVWWRILWWKHDODUPV
- If there is an appliance in a room where people sleep, place a CO Alarm in
this room
- Locate a CO Alarm in a room containing a flueless or open-flued appliance, and

- In a bedsit, the CO Alarm should be placed as far away from the cooking
appliance as possible, but near to where the person sleeps
- If the appliance is in a room not normally used, such as a boiler room, the CO Alarm
should be placed just outside the room so that the Alarm will be heard more easily.
3.2 Unsuitable Locations
Do not place the CO Alarm in any of the following areas.

Caravans and boats
Caravans and boats may have additional risks of carbon monoxide ingress through
air vents due to the nearby presence of other vehicles, engines, generators or
barbecues, however this does not change the basic guidance on location of the
Alarm. Caravans and boats should be fitted with an Alarm in the same room as

it can be considered to be equivalent to a bedsit, and a single Alarm is sufficient.
However, any sleeping accommodation which is in a separate room from the

Choosing locations in caravans and boats
It is not always possible to find an optimum location for an Alarm, for example,
a small caravan or boat may not have suitable vertical surfaces available.

potential source.
Interfering Substances
- The apparatus should not be exposed to excessive amounts of fumes from petrol,
diesel, solvents, greases, alcohols and organic cleaning fluids.
- The apparatus may respond to brief exhaust gas emissions e.g. during initial
start-up of an appliance or engine.
- Hydrogen acts as an interferent and may give rise to alarms. Hydrogen can arise
from some battery charging activities and also the curing of concrete under
certain circumstances.
Testing with CO
It is recommended that at least once per year that the apparatus is tested with
Carbon Monoxide, particularly in recreational vehicles.

4. Installation
Warning: The Installation of this CO Alarm should not be used as a subsitute
for proper installation, use and maintenance of fuel buring appliances including
appropriate ventilation and exhaust systems.
4.1 Installation Procedure
1. Select a location complying with the advice in ‘Where
to place CO Alarms’ section.
2. Remove the mounting plate from the packaging/
Alarm.
3. Place the mounting plate on the ceiling/wall exactly
where you want to mount the Alarm. With a pencil, mark
the location of the two screw holes.
4. Taking care to avoid any electrical wiring in the ceiling,
drill holes using a 5.0mm drill bit through the centre of
the marked locations. Push the plastic screw anchors
provided into the drilled holes. Screw the mounting plate
to the ceiling/wall. If wall mounting the CO Alarm, the
panel pin may be used as an alternative to the screws,
provided it is suitable for the mounting surface.
5. Alternatively, if desired, the CO Alarm will also free
stand on a flat surface with the mounting plate attached.

5. Monitoring, Testing & Maintenance
Monitoring
The CO Alarm self checks vital functions to ensure that it is operating correctly.
1. Low battery fault – the battery voltage is measured and compared against a
low voltage threshold.
2. Sensor Fault – the sensor is checked for electrical continuity and open circuit.
