The main advantage of the primary storage based on linear transformer scheme is the ground potential on the capacitor bodies during the shot, allowing exclusion of the total output voltage insulation of the highest stages, and to trigger all the stages simultaneously by using an external trigger pulse. The problem was to build a fast linear

The BTA combines both detection and activation for a single FirePro condensed aerosol generator. In case of a fire, once the temperature in the enclosure reaches the pre-selected detection rating (57°C, 68°C, 79°C, 93°C, 141°C, 182°C), the bulb will burst and mechanically activate the FirePro generator. The BTA operates without electricity.
