READ THIS FIRST WARNING The Alarm should be permanently wired to the mains by a qualified electrician in accordance with IEE wiring regulations (BS7671). Install the Carbon Monoxide Alarm (CO Alarm) in every room that contains a fuel burning appliance, particularly rooms where people spend a lot of time e.g. bedrooms, kitchens and sitting rooms.
B15404-R0-261EN-UC-ENG ? 31/5/07 2:01 PM Page 4 What to do when the alarm sounds: (1) Open the doors and windows to ventilate the area. (2) Turn off all fuel appliances where possible and stop them. (The alarm can be silenced immediately by pushing the test/hush button). (3) Evacuate the property leaving the doors and windows open. (4) Get medical help immediately for anyone suffering the effects of Carbon Monoxide poisoning (headache, nausea), and advise that Carbon Monoxide poisoning is suspected.
B15404-R0-261EN-UC-ENG ? ? 31/5/07 2:01 PM Page 5 The CO Alarm will automatically reset once the CO has cleared. Pressing the test/hush button resets the CO Alarm immediately (below 300ppm CO). If CO is still present the red light and horn will turn on again after about 4 minutes.
B15404-R0-261EN-UC-ENG 31/5/07 2:01 PM Page 6 Many are killed each year, and many more suffer ill health from Carbon Monoxide (CO) poisoning. CO is an invisible, odourless, tasteless and extremely 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.
B15404-R0-261EN-UC-ENG 31/5/07 2:01 PM Page 7 A high level of CO for a short period (e.g. 350 ppm CO for 30 minutes) will cause the same symptoms, a slight headache, as a lower level for a longer time (e.g. 150 ppm for 90 minutes). Table A shows how exposure to different concentrations of CO generally affects people.
B15404-R0-261EN-UC-ENG 31/5/07 2:01 PM Page 8 2.3 What happens when your CO Alarm detects Carbon Monoxide ? When the Alarm detects potentally dangerous levels of CO, it flashes the red alarm light and then sounds a loud alarm if the CO persists. The digital display indicates the CO level in parts per million, ppm CO, (Model Ei261DEN only). Table B 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.
B15404-R0-261EN-UC-ENG 31/5/07 2:01 PM Page 9 NEVER IGNORE THE ALARM. Pre-Alarm: When the alarm detects over 50ppm CO the red light flashes every 2 seconds. This helps locate CO leaks as the unit gives an indication straight away. (Without this feature the CO level would need to be at 50ppm CO for 90 minutes for an indication to be given). Note the Pre-Alarm signal may be triggered by CO coming for example, from cooking with gas, from car engines or from nearby barbecues.
B15404-R0-261EN-UC-ENG 31/5/07 2:01 PM Page 10 When the test button is held for 20 seconds the peak reading resets to zero. (Cover the horn with a cloth to muffle the loud alarm). Please note that the memory will also be reset when the unit is removed from the mounting plate. 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.
B15404-R0-261EN-UC-ENG 31/5/07 2:01 PM Page 11 3.2 Unsuitable Locations Do not place the CO Alarm in any of the following areas. (1) In the immediate vicinity of a cooking appliance (keep it at least 1 metre horizontally from it). (2) Outside the building. (3) In an enclosed space (e.g. in or below a cupboard). (4) In a damp or humid area. (5) Directly above a sink or cooker. (6) Next to a door, window, air vent or anywhere that it would be affected by draughts.
B15404-R0-261EN-UC-ENG 31/5/07 2:01 PM Page 12 3.3 If locating the CO alarm in a room with a fuel burning appliance (see figure 2) • If it is mounted on a wall, it should be located at a height greater than the height of any door or window but still be at least 150mm from the ceiling. • If it is mounted on the ceiling it should be at least 300mm from any wall or light fitting. • The CO alarm should be a horizontal distance of between 1m and 3m from the potential CO source.

INSTALLING YOUR CARBON MONOXIDE ALARMS The Alarm is designed to be permanently mounted, using its own built-in terminal block to connect it to the mains. The mounting plate can be screwed directly to the ceiling. Alternatively it can be screwed to a standard junction box (BS 4662 single gang accessory box). It requires a current of 60mA. The Alarm must not be exposed to dripping or splashing. There are important markings on the underside of the alarm.
B15404-R0-261EN-UC-ENG 31/5/07 2:01 PM Page 16 INSTALLATION PROCEDURE (1) Select a location complying with the above advice. (2) Disconnect the AC mains supply from the circuit that is going to be used. (3) The house wiring must be connected to the terminal block on the mounting plate as follows: L: Live - connect to the house wires coloured brown or marked L. N: Neutral - connect to the house wires coloured blue or marked N.

These Carbon Monoxide Alarms should be interconnected only within the confines of a single family living unit. If they are connected between different units there may be excessive nuisance alarms. Everybody may not be aware that they are being tested etc.
B15404-R0-261EN-UC-ENG 31/5/07 2:01 PM Page 20 5. TESTING YOUR CO ALARM (1) Regularly check that the green mains power light is on. The unit cannot detect CO if the mains power is not on and the rechargeable battery is depleted. (If it is off check circuit breakers, fuses, wiring etc). (2) Test the unit weekly by pressing the test/hush button. Hold the test button (for up to 10 seconds) until the horn sounds for over 5 seconds.
B15404-R0-261EN-UC-ENG 31/5/07 2:01 PM Page 21 Testing with Carbon Monoxide The unit checks for CO every 4 seconds and as soon as it detects CO it flashes the red light (as per Table B) to confirm that is detecting CO gas. Alternatively: Pressing the test button causes the unit to check for CO - this is the Fast CO Test Mode. This eliminates the long wait normally required e.g. up to 90 minutes at 55ppm CO and up to 3 minutes at 330ppm CO.
B15404-R0-261EN-UC-ENG 31/5/07 2:01 PM Page 22 6. MAINTAINING YOUR CO ALARM Clean the outside case by occasionally wiping with a clean damp cloth, (disconnect the mains supply at the distribution/fuse board first). Do not use any cleaning agents, bleaches, detergents or polishes, including those in aerosol cans. Avoid spraying air fresheners, hair spray, paint or other aerosols near the CO Alarm. Do not place air fresheners near the unit.
B15404-R0-261EN-UC-ENG 31/5/07 2:01 PM Page 23 After 5 years operation, the amber light will flash once every 40 seconds (without a beep) to indicate the sensor should be replaced. (Note: cover the ‘replace sensor’ label on side of unit with the new ‘replace unit’ by label supplied with the new sensor). It must also be replaced if the amber light flashes and the unit beeps every 40 seconds as this indicates the sensor is faulty. Remove the alarm from the mounting plate as described above.
B15404-R0-261EN-UC-ENG 31/5/07 2:01 PM Page 24 CO Alarms are fitted both near and in bedrooms, particularly if bedroom doors are closed at night. Additionally install in rooms where members of the household spend much of their time, and in rooms with potential sources of CO gas. (3) The CO Alarm may not be heard. The sound output is loud but it may not be heard behind a closed door or if it is too far away. Interconnecting CO Alarms greatly improves the probability that they will be heard.
B15404-R0-261EN-UC-ENG 31/5/07 2:01 PM Page 25 8. HOW TO PROTECT YOUR FAMILY Follow these guidelines to reduce the risk of Carbon Monoxide poisoning. (1) Know and look out for tell-tale signs that Carbon Monoxide may be present. These include:- The CO Alarm warning of abnormal levels. Staining, sooting or discolouration on or around appliances. A pilot light frequently going out. A strange smell when an appliance is working. A naked gas flame which is yellow or orange, instead of the normal blue.
B15404-R0-261EN-UC-ENG 31/5/07 2:01 PM Page 26 (7) Never use a gas cooker or a barbecue for home heating. (8 Children should be warned of the dangers of CO poisoning and instructed never to touch, or interfere with the CO Alarm. Do not allow small children to press the test/hush button as they could be subjected to excessive noise when the unit alarms. (9) Leaving windows or doors slightly open (even a few inches) will significantly reduce the risk of high levels of CO occurring.
B15404-R0-261EN-UC-ENG 31/5/07 2:01 PM Page 27 Electromagnetic Compatibility : Complies with BS EN 50270 Test/Hush Button : Checks electronics and horn. When the unit is alarming, after sensing CO, pressing the test/hush button will immediately stop the horn (the red light will continue to flash). If CO is still present the red light and the horn will turn on again after about 4 minutes. The unit can only be silenced once during a CO incident. At 300 ppm CO the unit cannot be silenced.
B15404-R0-261EN-UC-ENG 31/5/07 2:01 PM Page 28 Rechargeable Lithium Cells: : Fully charged cells can power unit in standby for over 4 weeks. It can power the unit in alarm for over 2 hours. The unit beeps every 40 seconds if cells are depleted. Interconnect : Up to 12, Ei 261EN/261DEN Alarms can be interconnected, so that when one senses CO, all alarm. Relay Module Ei128C (optional) : This can be connected, using the interconnect line. Use relay contacts for for switching valves etc.
B15404-R0-261EN-UC-ENG 31/5/07 2:01 PM Page 29 10. GETTING THE CO ALARM SERVICED If your CO Alarm fails to work after you have carefully read all the instructions, checked the unit has been installed correctly, and is receiving AC power, - see “How to disconnect and remove the Alarm” in section 5. Return it for repair or replacement. (Do not attach to mounting plate as unit can give beeps or alarm if the button is pressed during shipping).
B15404-R0-261EN-UC-ENG 31/5/07 2:01 PM Page 30 12. TROUBLESHOOTING 1. ALARM DOES NOT WORK WITH THE TEST BUTTON: (1) Check that the green mains power light is on. If it is off check the wiring, fuse, circuit breakers etc. (2) Hold the test button down for at least 5 seconds. 2. ALARM BEEPS AND AMBER LIGHT FLASHES EVERY 40 SECONDS: If the alarm beeps and the amber fault light flashes every 40 seconds, the CO sensor is probably defective. Press the test/hush button to reset the unit.
B15404-R0-261EN-UC-ENG 31/5/07 2:01 PM Page 31 (2) Ensure there are no fumes in the area (e.g. paint, thinners, alcohol, hair spray, chemical cleaners aerosol sprays etc). (3) Ensure there is no outdoor source of CO in the vicinity (e.g. a car with engine running, heavy traffic, heavy air pollution, barbecue fumes etc). (4) Press the test/hush button to silence the alarm.
