NSHEV are normally provided with a standard individual device consisting of an actuator with MINI-TERMICO™ group. The latter is equipped with mini CO2 cylinders and a thermosensitive element, usually calibrated at 68°C, which can be replaced with other elements calibrated at higher temperatures.
In this case the smoke ventilator is activated exclusively by detecting an equal or higher temperature than that the one set by thermosensitive element.
After each event, both emergency and test, thermosensitive elements and CO2 cylinders have to be replaced, while the actuator has to be reset.
