7. Alarm Limitations
Limitations of Smoke/Heat Alarms
Smoke/Heat 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:
• Smoke/Heat Alarms will not work if they are not connected to the RFAP. Test
regularly and replace the entire Alarm when it fails to operate.
• Smoke/Heat Alarms will not detect fire if sufficient smoke or 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 or heat
away. Installing Smoke/Heat Alarms on both sides of closed doors and installing
more than one Alarm as recommended in this leaflet very significantly improve the
probability of early detection.
• The Smoke/Heat Alarm may not be heard.
• A Smoke/Heat Alarm may not wake a person who has taken drugs or alcohol.
• The 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, children playing with
matches.
