2. POSITIONING THE HEAT ALARM
For best protection the heat alarm should always be installed as part of a
complete fire protection system that also includes smoke alarms.
Heat alarms are best suited to areas where dust, fumes and moisture can cause
nuisance in smoke alarms, such as:
• Boilerrooms
• Kitchens
• Lofts
• Laundryrooms
• Garages
• Bathrooms
Heat alarms should not be installed in escape routes instead of smoke alarms
-theyshouldonlybeusedintheaboveapplications.(Sentechsmokealarms

the house.)
When heat alarms are installed in a room, they should be placed on the ceiling,
ideallyinthecentreoftheroom.Theyshouldbeatadistancenomorethan5.3m
