How the heat alarm system works
The heat alarm system is an additional tool for laser machines.
Some materials such as acrylic, wood and so on, can easily catch fire, particularly during
cutting.
The heat alarm system has a smart board with temperature sensor which will be reacted
by an abnormal temperature (higher than 55°C/131°F) on working table. It will trigger at a
certain temperature them signals to TL-Timer board to stop laser processing and give a
warning sound, so operator can active fire control in time to reduce the potential losses
and risks.
The warning sound comes from signal lamp (roughly 80dBA within 1m, 75dBA within 5m
and 65dBA within 10m, the sound gets weaker as it travels).
Note: When heat alarm system is activated, the warning sound will beep all the time until
user restart the machine.
How to check when the heat alarm system has needless alarm
 The smart board has short circuit on temperature sensor
The smart board is installed in the middle under the X-axis rail, see below pics.
