16 17 MASTER CONTROL UNIT Operating Principle The master control unit features the most used keys on the control panel of the fi refi ghting vehicle in one functional unit. The controls are very clearly represented graphically. The master control unit is divided into a grid of fi ve horizontal and fi ve vertical lines. The buttons or warning LEDs can be located at each intersection. Relay outputs for the inductive load or power MOSFET outputs are also available. It can control solenoid valves, lights, sirens or other custom needs.
