1. READ THIS FIRST WARNING: The Ei225EN Alarm should be permanently wired to the mains by a qualified electrician in accordance with IEE wiring regulations (BS7671). The Ei220EN is just plugged in to the mains. 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.
When the CO Alarm detects abnormal levels of CO (above 50ppm CO) the red light starts to flash and the horn will sound within 90 minutes. At higher levels of CO the alarm will turn on sooner (see table B - page 9). ? 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.
(5) Ring your gas or other fuel supplier on their emergency number. Keep the number in a prominent place. (6) Do not re-enter the property until the alarm has stopped. (If the alarm has been silenced by pressing the test/hush button, wait at least 5 minutes so the alarm can check that the CO has cleared). (7) Do not use the fuel appliances again until they have been checked by an expert. In the case of gas appliances this must be a CORGI registered installer. Figure 1 - Alarm Installation 3.
(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. High levels of CO in a house can be caused by: • Incorrectly or poorly installed fuel-burning appliances.
Mild Exposure: Slight headache, nausea, vomiting, fatigue (often described as “flu-like” symptoms). Medium Exposure: Severe throbbing headache, drowsiness, confusion, fast heart rate. Extreme Exposure: Unconsciousness, convulsions, cardiorespiratory failure, death. 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: Effects of Carbon Monoxide Poisoning Concentration of CO in Air Inhalation Time (approx) and Symptoms Developed ppm 35 The maximum allowable concentration for continuous exposure in any 8 hour period according to OSHA *. 150 Slight headache after 1.5 hours. 200 Slight headache, fatigue, dizziness, nausea after 2-3 hours.
Table B 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.
(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. 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 are released nearby.
4. 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.
(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. (7) Next to an extractor fan. (8) Where it would be obstructed, e.g. by curtains or furniture. (9) In an area where the temperature could drop below –10°C or rise above 40°C. (10) Where dirt or dust could block the sensor.
• The CO alarm should be a horizontal distance of between 1m and 3m from the potential CO source. • If there is a partition in the room, the CO alarm should be located on the same side of the partition as the potential source. • In rooms with sloped ceilings, the CO alarm should be located at the high side of the room (see fig 3). 300mm CO Alarm 150mm 1 to 3 m DEAD AIR DON'T LOCATE HERE 1 to 3 m Figure 2.
3.31 If locating the CO alarm in a bedroom or in rooms remote from a fuel burning appliance (see figure 4) • Mount the CO alarm relatively close to the breathing zone of the occupants. Whatever position is chosen make sure it is possible to view the three light indicators, when in the vicinity of the alarm. 300 m m CO Alarm CO Alarm about 1 to 2m Figure 3. Location in rooms with sloped ceilings, the CO alarm should be located at the high side of the room 14 Figure 4.
5. INSTALLING YOUR CARBON MONOXIDE ALARMS The Alarm is designed to be permanently mounted. The unit can be screwed directly to the wall or ceiling and connected to the mains. 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. IMPORTANT PRECAUTION: Do not install the actual alarm itself in new or renovated buildings until all work is completed (including floor coverings) and the building has been fully cleaned.
INSTALLATION PROCEDURE Ei225EN (Only) Warning: The CO alarm should be installed by a qualified electrican in accordance with the IEE wiring regulations (BS 7671). Failure to install this alarm correctly may expose the user to shock or fire hazards. Procedure: 1. Select a location complying with the above advice. 2. Disconnect the AC mains supply from the circuit to be used. 3. Slide off the cover as shown in fig 1. Press gently in the centre to release the catches before sliding upwards. 4.
6. The Brown wire (terminal 3) must be connected to the house wiring coloured brown or to a house terminal marked “L”. The Blue wire (terminal 4) must be connected to the house wiring coloured blue or to a house terminal marked “N”. The alarm does not need to be earthed, however for convenience a spare terminal (no. 5) is provided to hold an earth wire if present. 7. Turn on the mains power to the CO Alarm circuit.
Ei220EN (Only) 1. Slide the cover off as shown in Figure 7 to expose the mounting screw holes. 2. Cut a notch in the back sidewall (on the centre of either side or at the bottom, for the power cord) to allow the unit to lie flush against the ceiling/wall. 3. Mark the two screw locations. Drill suitable holes (6mm drill) then insert the plastic anchors and screw the unit to the ceiling/wall. 4. Insert the plug into a suitable socket.
6. 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. (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. This will help to familiarise you and your family with the distinctive on-off sound of the CO Alarm.
inject the CO gas into the gas entry holes, see Figure 1. When it senses the CO it flashes the red light (as per Table B) to confirm that is detecting CO gas. How to distinguish between CO Alarm and Smoke Alarm Warnings The CO Alarm has a distinctive on-off sound of 3 pulses, followed by a pause as compared with a typical Smoke Alarm which has a rapid pulsing sound. In addition, when your CO Alarm is sounding, the red alarm light in the centre of the cover will be flashing.
Remove the CO Alarm when decorating. Do not allow water or dust to contaminate the alarm. Warning: Do not open or tamper with the CO Alarm. There are no user serviceable parts. This can damage the unit and may expose the user to shock or fire hazards. END OF LIFE When the unit has completed up to 6 years of operation the amber light will flash every 40 seconds. The entire unit must then be replaced. It must also be replaced when the date on the ‘Replace unit by’ label on the side wall is exceeded.
3. Unscrew the terminal cover screw. 4. Disconnect the wires from the terminal block and make safe, particularly if the circuit is going to be turned on again after the CO Alarm is removed. 5. Unscrew from the wall. Ei220EN only 1. Unplug the unit. 2. Slide cover up as shown in figure 7. 3. Unscrew from the wall. 8. LIMITATIONS OF CO ALARMS (1) The CO Alarm will not work without mains power. The green power light must be on at all times as far as possible.
(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. The Alarm may not wake up somebody who has taken alcohol or drugs. The alarm sound may be masked by other sounds such as T.V., stereo, traffic noise etc. Fitting CO Alarms on either side of closed doors will improve their chance of being heard. This CO Alarm is not designed for people with impaired hearing. (4) CO Alarms don’t last indefinitely.
THE ACUTE EFFECTS OF CARBON MONOXIDE EXPOSURE. IT WILL NOT FULLY SAFEGUARD INDIVIDUALS WITH SPECIFIC MEDICAL CONDITIONS. IF IN DOUBT CONSULT A MEDICAL PRACTITIONER. 9. 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.
air comes from and ensure vents/air bricks etc. remain unobstructed (particularly after building work). (4) The appliances must also “breathe out” the waste gases (including the CO) – usually through a flue or chimney. Ensure chimneys and flues are not blocked or leaking, and get them checked every year. Check for excessive rust or cracks on appliances and pipe work. (5) Never leave your car, motor bike or lawnmower engine running in the garage with the garage door closed.
