1. General Information
This is a heat alarm device that is activated when it
reaches a preset minimum heat warning level
(around 59°C). It is not a smoke detector. If the heat
alarm is properly located and maintained, it will
detect dangerous heat levels caused by the
emergence of a fast flaming fire. Please note –
although this heat alarm is designed to detect
dangerous heat levels, it cannot prevent a fire.
Please read the User Manual carefully before you
install this heat alarm.
