Temperature monitoring unit
Use
The temperature monitoring unit is ready connected to the actuator and is used for forced
control of motorized fire and smoke protection dampers, should excessive temperatures
occur.
Mode of operation
The temperature monitoring unit contains 2 thermal fuses, 1 for monitoring the duct
temperature and 1 for the ambient temperature. If the temperature at any of these fuses
exceeds the level of 72 °C (optionally: 95 °C), the power supply will be irreversibly cut. AS a
result, the return spring will drive the actuator to the failsafe position. A test button is
integrated for making functional checks. When pressed, the current path will be cut.
