This apparatus is designed to protect individuals from the acute effects of carbon monoxide exposure. It will not fully safeguard individuals from specific medical conditions. If in doubt consult a medical practitioner.
The CO5B and CO7B range of alarms will go into the alarm condition under the following circumstances:
Carbon Monoxide Level (Parts per million) | No Alarm Before | Alarm Before |
30 ppm | 120 mins | - |
50 ppm | 60 mins | 90 mins |
100ppm | 10 mins | 40 mins |
300ppm | - | 3 mins |
The FireHawk CO5B and CO7B range of battery operated Carbon Monoxide alarms are ideal for the home and travelling on holiday. It's compact size takes up little room in the baggage but gives you invaluable protection from faulty heating and cooking appliances wherever you are.
If fitted, the LCD display on the CO7BD allows you to read harmful levels of Carbon Monoxide (CO) in ppm (parts per million) at the click of the display button. Further clicks show the peak CO levels in the previous 12 hours and % COHb (carboxy-haemoglobin or CO in the blood).
Three LED's on the front of the alarm indicate Alarm (red) when the alarm has detected harmful levels of CO; Power, (green) flashes one every minute when the alarm is operating and Fault (yellow) indicates a fault in the alarm. All three LEDs operate with different sound patterns as shown in the Table 1.
If the alarm sounds a repeating series of 4 beeps, (see Table 1) evacuate the property immediately. If it is not possible for all occupants to exit the property for any reason, call for help, open all doors and windows to ventilate it and move to fresh air.
IN THE CASE OF SUSPECTED CARBON MONOXIDE (CO) POISONING, SEEK MEDICAL ASSISTANCE IMMEDIATELY.
Do not silence the alarm or re-enter the property until the source of Carbon Monoxide (CO) has been found and dealt with by a competent and registered Gas Safe engineer.

The alarm will reset itself if the CO dissipates naturally.
The design and layout of domestic premises and the number, type and position of carbon monoxide sources vary widely. However, general guidance is given below on where and where not to locate the alarm in order to minimise the risk of misleading indications.
Which room?
Ideally, an alarm should be installed in every room containing a fuel burning appliance. Additional alarms may be installed to ensure that adequate warning is given for occupants in other rooms, by locating alarms:
Where in the room?
It should be possible to view all the light indicators on the alarm when in the vicinity of the chosen location for the alarm. It is not possible to give specific guidance on the exact location of a alarm which suits all types of room and their usage. The following points should be taken into consideration when determining an optimum location for any appropriate situation:
Where not to install the alarm
The alarm SHOULD NOT be installed:
An alarm located in the same room as a fuel-burning appliance:
An alarm located in sleeping rooms and in rooms remote from a fuel burning appliance:
An alarm that is located in sleeping rooms and in rooms remote from the fuel-burning appliance should be located relatively close to the breathing zone of the occupants. (The breathing zone should be regarded as the horizontal level in the room where a person's head spends most of the time, ie while sat in a chair or laid on a pillow.
Pay particular attention to the normal location of the elderly and disabled when reaching a decision. For further information contact the manufacturers helpline on 01322 342 238 or CoGDEM (The Council for Gas Detection and Environmental Monitoring) on their helpline 0800 1694 457
Particular attention should be given to sleeping accommodation. Carbon Monoxide is particularly hazardous to a person while asleep as it will not wake them. If they wake and have been subjected to carbon monoxide, they may be too disorientated to know what is wrong with them and what to do next. A Carbon Monoxide alarm at the bed head will help to avoid this situation
Do not operate this alarm in areas with temperatures less than -10°C or greater than +40°C; or in humidity less than 30% RH or more than 90% RH.
This apparatus should be installed by a competent person.
As a portable Device:
Fixing the alarm to a wall:
NOTE: To Remove the alarm from the baseplate, depress the tag fully towards the back of the baseplate and slide the alarm towards the top. See Fig 5.
Tampering with this alarm may cause a malfunction
Testing the alarm
Test the alarm once a week using the test button. It should flash all three LEDs once, one after another, followed by 4 beeps from the sounder.
Cleaning the alarm
Regular cleaning of the alarm is essential if it is to work properly. Keep free of dust and vacuum it every month and ensure the vents are clear. Every six months wipe the outside with a damp cloth to remove staining and grease from cooking etc.
Battery Information
The battery is sealed in and is not replaceable. It should last 5 years for the
CO5B and 7 years for the CO7B range; the life of the alarm. After approximately 5 or 7 years, depending on the model, the alarm will beep three times every minute to indicate end of life. At this point the alarm should be replaced. Extended periods in alarm mode can significantly reduce the life of the battery.
In the unlikely event of a fault developing in your alarm, it will emit two beeps every minute (see Table 1). If this happens DO NOT OPEN THE ALARM, there are no user serviceable parts inside. Remove it from the baseplate to turn it off and return it to the manufacturer at the address at the end of this handbook.
Carbon Monoxide (CO) is an extremely poisonous gas. It is a colourless, odourless and tasteless gas released by the incomplete combustion of fossil fuels such as natural gas, bottled gas, petrol, diesel, oil, paraffin, wood, coal coke and bio-fuels.
When inhaled, it causes chemical asphyxiation, when CO mixes with the blood and reduces the oxygen carried around the body, in particular to the brain. The following symptoms are typical of CO poisoning and should be discussed with all members of your household.
Mild Exposure:
Slight headache, nausea, fatigue, often thought to be flue symptoms. Think CO.
Medium Exposure:
Severe throbbing headache, drowsiness, confusion, vomiting and fast heart rate.
Extreme Exposure:
Unconsciousness, Convulsions, Cardio-respiratory failure, death.
Although feeling unwell, victims of CO poisoning become so disoriented that they can no longer decide what to do next, including being unable to exit the building or call for assistance. Very young children often show symptoms earlier than adults.
Being affected while asleep is the most dangerous situation as the victim will not wake as a result.
A correctly operating and serviced fossil fuel burning appliance should allow complete burning of the fuel and therefore is not a hazard. You should have all such appliances serviced at least once a year by a fully qualified Gas Safe registered engineer.
TYPICAL SOURCES OF CARBON MONOXIDE AROUND THE AVERAGE HOUSEHOLD ARE:
Room heaters; such as real flame fires, wood-burners, ranges; open coal, coke and wood fires, portable gas and paraffin heaters. Central heating boilers. Oil fired and gas central heating boilers, wood-burners and automated feeders for coke and coal.
Cookers and solid fuel ranges.
NOTE: Cooker hoods without flues will not remove CO.
Barbecues and chimneas used outside but close to the property
Petrol and diesel driven engines such as cars, motorbikes, lawn movers, strimmers, rotovators, chain saws etc, especially when run up inside the garage or garden shed.
Cigarette, cigar and pipe smoke. Carbon monoxide from burning tobacco can build up over even a short time, particularly in a poorly ventilated property. Blocked flues from fires, ranges and boilers. A partially blocked flue will cause a build up of unburned gasses in the system and, if damaged by building movement or poor condition, could either severely affect complete burning or leak combustion gases into the property, particularly when they take air from the room to improve efficiency of exhaust.
Incorrect Installation of Equipment Always use a registered Gas Safe Installation Engineer.
Faulty Equipment; Cracked /blocked flues or cracked heat exchangers Insufficient Ventilation for Complete Combustion. Where appliances take air for combustion from the room such as open wood and coal fires, portable gas or paraffin heaters or space-heating boilers, the room MUST have adequate ventilation to allow sufficient air for complete combustion. DO NOT block up room vents specifically provided for this purpose. Appliances Competing for Air Supply Where there is more than one appliance taking air from a room ensure that there is an adequate supply.
Air tightness of the Property. This can happen if there is a lack of unobstructed ventilation in the presence of double glazing.
Holiday Accommodation. Take particular care when using holiday accommodation at home or abroad. Make sure you understand the type of appliances you are using and take note of the fuel being used. The CO5B and CO7B ranges of Carbon Monoxide alarms are particularly suitable for this. Always take the handbook with you and read these instructions.
HAVING A WORKING CARBON MONOXIDE ALARM IN YOUR PROPERTY SHOULD NOT BE SEEN AS A REASON TO AVOID THE REGULAR SERVICING OF FUEL BURNING APPLIANCES.
