Abstract
A firing device is described and has an electronic unit which is connected upstream of a firing cap and generates a constant firing voltage. A bypass line is provided for bypassing the electronic unit. A test switching device can be actuated by a test signal and, when a test signal is present, connects a line, which conducts a supply voltage, to the bypass line. In this way, a Brouston test can be carried out.
