The unit is suitable for use in areas where cooking and heating appliances burn fuels such as wood, charcoal, coal, coke, oil, petrol, gas, etc.
WHAT IS CARBON MONOXIDE
Carbon Monoxide (CO) is a highly poisonous gas which is released when fuels are burnt. It is invisible, has no smell and is therefore very difficult to detect with the human senses. The first warning symptoms that CO is present in the air are usually headaches and nausea. Under normal operating conditions, in a room where fuelburning appliances are well maintained and correctly ventilated, the amount of Carbon Monoxide released into the room by the appliances is not dangerous. A dangerous quantity of Carbon Monoxide can occur if one or more of the following conditions exists:
1.An appliance is faulty or is badly maintained.
2.A flue is partially or totally blocked.
3.A room is not adequately ventilated.
CAREFULLY READ AND UNDERSTAND THE CONTENTS OF THIS INSTRUCTION MANUAL BEFORE USING THE ALARM. RETAIN THE MANUAL IN A SAFE PLACE FOR FUTURE REFERENCE.
PAY PARTICULAR ATTENTION TO THE SAFETY WARNINGS. PASS THE MANUAL ONTO ANY SUBSEQUENT USERS OF THE ALARM.
WARNING
THIS Carbon Monoxide ALARM MAY NOT PROTECT PEOPLE WHO ARE AT SPECIAL RISK FROM Carbon Monoxide EXPOSURE BY REASON OF AGE, PREGNANCY OR MEDICAL CONDITION. IF IN DOUBT, CONSULT YOUR MEDICAL PRACTITIONER.
This Carbon Monoxide Alarm is NOT:
•A substitute for either a smoke alarm or a combustible gas detector.
•To be seen as a substitute for the proper servicing of fuel-burning appliances or the sweeping of chimneys
•To be used on an intermittent basis, or as a portable detector for the spillage of combustion products from fuel-burning appliances or chimneys.
CAUTION
This Carbon Monoxide alarm is designed for indoor use only. Do not expose to rain or moisture. Do not knock or drop the unit. Do not open or tamper with the unit as this
could cause malfunction.
The alarm will not protect against the risk of Carbon Monoxide poisoning when the battery has drained.
IMPORTANT
•Carbon Monoxide is produced by the incomplete combustion of fuels such as wood, charcoal, coal, heating oil, paraffin, petrol, natural gas, propane, butane etc.
•Ideally, it is recommended that a Carbon Monoxide alarm should be installed in or near to every room that has a fuel burning appliance such as any gas fires, central heating boiler, room heaters, water heaters, cookers, grills, etc.
•This alarm should only be installed by a competent person.
•Ensure that the audible alarm can be heard by all those who are intended to hear it.
•This product should not be used if any fault signals are given.
•Seek medical help if it is suspected that a member of the household is suffering from Carbon Monoxide poisoning.
•If further details are required which do not appear in this manual, contact Honeywell Analytics.

EFFECTS OF CARBON MONOXIDE POISONING
Carbon Monoxide binds to the haemoglobin in the blood and reduces the amount of oxygen being circulated in the body.
200ppm Slight headaches, tiredness, dizziness, nausea after 2-3 hours.
400ppm Frontal headache within 1-2 hours, life threatening after 3 hours.
800ppm Dizziness, nausea and convulsions within 45 minutes. Unconsciousness with 2 hours. Death within 2-3 hours.
1600ppm Headache, dizziness and nausea within 20 minutes. Death within 1 hour.
6400ppm Headache, dizziness and nausea within 1-2 minutes. Death within 10-15 minutes.
POSITIONING THE ALARM
1.Units located in the same room as a fuel-burning appliance
•If the unit is located on the wall it should be located at a height greater than the height of any door or window but at least 150mm from the ceiling. If the unit is mounted on the ceiling it should be at least 300mm from any wall.
•The unit should be at a distance of between 1m and 3m from the potential source.
•If there is a partition in a room, the unit should be located on the same side of the partition as the potential source.
•In rooms with sloped ceilings, the unit should be located at the high side of the room.
2.Units located in sleeping rooms and in rooms remote from a fuel burning appliance
•Units should be located relatively close to the breathing area of the occupants.
WHERE NOT TO PUT THE ALARM
Do not place the unit in the following areas:
•Outside the building.
•In or below a cupboard.
•In a damp or humid area.
•Directly above a sink or cooker.
•Next to a door or window or anywhere that would be affected draughts, eg, extractor fan or air vent.
•Where the air flow to the unit would be obstructed by curtains or furniture.
•Where dirt or dust could collect and block the sensor, and stop it working.
•In an area where the temperature could drop below -10˚C or rise to above 40˚C.
•Where it could be easily knocked, damaged, or where it could be inadvertently removed.
IN WHICH ROOM TO PUT THE ALARM
Ideally, an alarm should be fitted in every room that contains a fuelburning appliance. However, if there is more than one appliance and the number of units is limited, the following points should be taken into consideration when deciding on the best location:
•If there is an appliance in a room where people sleep, a unit should be placed in that room.
•A unit should be located in a room containing a flueless or open-flued appliance.
•If there is an appliance in a room which people use a lot, such as a sitting room, a unit should be placed in that room.
•In a bedsit, the unit 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 unit should be placed just outside the room so that the alarm will be heard more easily.
INSTALLING THE ALARM
The unit can either be free-standing or wall mounted, using the fixings provided.
WALL MOUNTING INSTALLATION
Find a position to install the unit (see“where to put the alarm” and “where not to put the alarm”).
mounting pad
fixing pin
wall wall plug
5mm
screw wall
Option 1 Special Mounting Pad with Fixing Pin (supplied)
Place the fixing pin through the mounting pad. Using a hammer, gently knock the fixing pin into the wall ensuring that the mounting pad is not hammered too firmly into the wall.
Option 2 Screw and wall plug (NOT supplied)
If the wall is too hard to use the fixing pin, use a No. 4 round head screw and wall plug.
Once activated and tested (see “using the alarm”), the unit can be hung on the protruding fixing pin using one of the ‘keyholes’ indicated on the back of the unit by the lines shown.
USING THE ALARM
To activate the unit, pull out the activation strip at the base of the unit. The green and red lights will flash briefly and the buzzer will sound a short chirp.
Press the test button and hold for up to 5 seconds and check that the red light flashes and the buzzer sounds.
The unit is now operating and is ready for use.
