For example, consider a pull station in the fourth-floor elevator lobby of an office building with a code of 5-3-1. When the station was pulled, the security officers in the building would look up 5-3-1 in a master list of codes. After finding the location of the pull, they should check to see if there is a real fire.
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 ...

The control action is the switching on/off of the boiler, but the controlled variable should be the building temperature, but is not because this is open-loop control of the boiler, which does not give closed-loop control of the temperature. In closed loop control, the control action from the controller is dependent on the process output.
