The most common causes of false alarms are:
Heat alarms have fixed-temperature elements and respond to the temperature of the fire gases in the immediate vicinity of the heat alarm. They are used where ambient temperatures are likely to fluctuate rapidly over a short period, such as in kitchens, and are less likely to produce false alarms. Elsewhere, heat alarms should not be used instead of smoke alarms to reduce unwanted false alarms.
