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.
The manufacturer recommends replacement of the Smoke /
Heat Alarms after 10 years as a precaution (see ‘Replace by’
label on side of unit).
What is the best Smoke Alarm - Optical or Ion ?
Both types respond in all standard fires but each type may
respond faster to particular fires as shown. The EI company
manufactures complementary 12 Volt Smoke Alarms , Optical
Smoke Alarm Ei105R3 & Ei105R4 and Ionisation Smoke
Alarm Ei100R3. For dual protection install each type.
