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. In rooms with an appliance install (perferably) on the ceiling (300mm from walls) and between 1m to

(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 poi- soning (headache, nausea), and advise that Carbon Monoxide poisoning is s

CO is an invisible, odourless, tasteless and extremely toxic gas. It is produced by appliances and vehicles burn- ing 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 starvat

Table A shows how exposure to different concentrations of CO generally affects people. Many cases of reported Carbon Monoxide poisoning indicate that while victims are aware they are not well, they become so disorientated they are unable to save themselves by e

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. The rate of

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. This is usually not

Please note that the memory will also be reset when the unit is removed from the mounting plate. 3.

(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. (7) Next to an extractor fan.

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 th

(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. IC: Interconnect - If you are only installing one alarm do not conn

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. This will help to familiarise you and your family with the dist
