    This comprises measurement of flow (FE) at the pump discharge, this measurement is an input to a flow controller (FIC) whose set point is the minimum flow required through the pump(see diagram). As the flow reduces to the minimum flow value the controller acts to open a flow control valve (FCV) to recycle fluid from the discharge back to the ...

    en.wikipedia.org/wiki/Fire_alarm_control_panel

    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 ...

    en.wikipedia.org/wiki/Proportional–integral...

    Tuning a control loop is the adjustment of its control parameters (proportional band/gain, integral gain/reset, derivative gain/rate) to the optimum values for the desired control response. Stability (no unbounded oscillation) is a basic requirement, but beyond that, different systems have different behavior, different applications have ...

    en.wikipedia.org/wiki/Control_panel_(engineering)

    A control panel is a flat, often vertical, area where control or monitoring instruments are displayed or it is an enclosed unit that is the part of a system [1] that users can access, such as the control panel of a security system (also called control unit).

  8. Fire pump - Wikipedia

    en.wikipedia.org/wiki/Fire_pump

    A jockey pump, also known as a pressure-maintenance pump, is a small pump connected to a fire suppression system near the fire pump and is intended to maintain pressure in a fire protection piping system. These pumps recover pressures lost from gradual, slow pressure declines in a system due to temperature changes, trapped air escapement, or ...

    Control panel for a Boeing 737-800 ECS. In aeronautics, an environmental control system (ECS) of an aircraft is an essential component which provides air supply, thermal control and cabin pressurization for the crew and passengers. Additional functions include the cooling of avionics, smoke detection, and fire suppression.
