(v) Turn on the mains supply at the distribution board only if the unit passes all the above tests. Note: If the mains is disconnected and the battery is almost depleted the unit will beep every 40 seconds for at least 72 hours. This is to remind you to re-connect the mains supply. The unit will operate from the mains alone, even with a fully depleted or a defective battery, though it may not give sufficient warning of fire if the mains supply is disconnected for any reason. If there are any problems get a qualified electrician to inspect the house wiring and connections to the alarms. If there are still problems the unit must be returned for examination (see section on Getting Your Alarm Serviced). CLEANING YOUR ALARM WARNING: Electrical shock hazard. Disconnect the AC mains at the fuse box or circuit breaker powering the Alarm before following the cleaning instructions. Clean your Alarm regularly,particularly in dusty areas. Use the narrow nozzle attachment of your vacuum cleaner to remove dust, insects and cobwebs from the sides and cover slots where the smoke or heat enters. To clean the cover, wipe with a damp cloth. Dry cover thoroughly with a lint free cloth. If the contamination around the outer case indicates that the area is particularly dirty, remove the Alarm from the ceiling (see figure 4 4. Call the Fire Brigade from a neighbour’s house. Remember to give your name and address. 5. NEVER re-enter a burning house. Limitations of Smoke Alarms Smoke Alarms have significantly helped to reduce the number of fire fatalities in countries where they are widely installed. However independent authorities have stated that they may be ineffective in some circumstances. There are a number of reasons for this: • The Alarms will not work if the mains power is off and in the case of the Ei 151TL, 154TL and 156TL if the cells are depleted. • Smoke / Heat Alarms will not detect fire if sufficient smoke / heat does not reach the alarm. Smoke / heat may be prevented from reaching the Alarm if the fire is too far away, for example, if the fire is on another floor, behind a closed door, in a chimney, in a wall cavity, or if the prevailing air draughts carry the smoke away. Installing Smoke / Heat Alarms on both sides of closed doors and installing more than one Smoke / Heat Alarm as recommended in this leaflet very significantly improves the probability of early detection. • The Alarm may not be heard. • A Smoke / Heat Alarm may not wake a person who has taken drugs or alcohol. • Smoke / Heat Alarms may not detect every type of fire to give sufficient early warning. They are particularly ineffective with: fires caused by smoking in bed, escaping gas, violent explosions. poor storage of flammable rags and/or liquids, (for example petrol, paint, spirits etc), overloaded electrical circuits, arson and children playing with matches. • Smoke / Heat Alarms don’t last indefinitely. For example if there is build up of contamination performance will be impaired, and in the case of the EI 151TL, 154TL or 156TL the rechargeable cells may eventually become too weak to function correctly in the event of a mains power failure. 8 12 ...
