    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.

  • Page 4: What To Do When The Co Alarm Sounds

    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.

    (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).
  • Page 6 (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.
  • Page 7 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.

Slight headache after 1.5 hours. Slight headache, fatigue, dizziness, nausea after 2-3 hours. Frontal headaches within 1-2 hours, life threatening after 3 hours, also maximum parts per million in flue gas (on an air free basis) according to US Environmental Protection Agency.

  • Page 10 (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.

    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. However if the number of Carbon Monoxide Alarms is limited the following points should be considered when deciding where best to fit the alarm(s) - If there is an appliance in a room where people sleep, place a CO Alarm in this room and - Locate a CO alarm in a room containing a flueless or open-flued appliance, and...
  • Page 12 Outside the building. In an enclosed space (e.g. in or below a cupboard). In a damp or humid area. Directly above a sink or cooker. Next to a door, window, air vent or anywhere that it would be affected by draughts.
  • Page 13 • 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. •...
  • Page 14 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.

    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.

    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.
