T-start is a unique autonomous thermal activation and detection device

T-start is a unique autonomous thermal activation and detection device that allows detecting a fire and activating a powder, aerosol or gaseous fire suppression system. Also the device has features such as provision of a signal to a fire panel and incorporation of an additional output designed to shut down the electrical equipment or activate an alarm (depends on a specific modification).

T-start can also be used as a thermal detector with a fixed temperature reading and can be connected to an existing fire detection circuit or a fire-indicating panel.

T(HZ)-start is a special design version of T-start containing an intrinsically safe interface and designed for use in hazardous areas.

The main feature of the automatically operated T-start is a special heat-sensitive element (7) with a rated temperature reading. When subjected to a fire or a heat the element expands at the rated temperature reading and releases a spring-loaded rod (10) mounted inside a nosepiece (9).

The spring moves a cylindrical shape magnet (4), which is mounted on the rod (10), through an induction coil (12). The induction coil generates an electric impulse. The impulse is transmitted to the electrical terminals (2) and further to the aerosol or powder fire extinguishers.
