Coded panels were the earliest type of central fire alarm control, and were made during the 1800s to the 1970s. A coded panel is similar in many ways to a modern conventional panel (described below), except each zone was connected to its own code wheel, which, depending on the way the panel was set up, would either do sets of four rounds of code until the initiating pull station was reset ...
A small, electrically powered pump A large, electrically driven pump for waterworks near the Hengsteysee, Germany. A pump is a device that moves fluids (liquids or gases), or sometimes slurries, [1] by mechanical action, typically converted from electrical energy into hydraulic or pneumatic energy.
The Bergmann Simplex was a semi-automatic weapon, operating on the principle of a free-bolt recoil. The lock consists of a simple single-action system, using hammer as a striker, without self-cocking. The Bergmann Simplex was fed from a replaceable box magazine with a capacity of 6 or 8 rounds.
