IMPORTANT INFORMATION WARNING: The Alarm should be permanently wired to the mains by a qualified electrician in accordance with IEE wiring regulations (BS7671). Install a Carbon Monoxide (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 (preferably) on the ceiling (300mm from walls and between 1m t

(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. (5)

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 (Model Ei261DENRC only) indicates the CO level in parts per million (ppm) CO. 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 rat

B16132-R0-261ENRC-UC-ENG 7/11/07 11:52 AM 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 the horn to sound). 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 conce
