The term "supervisory switch" in fire protection typically refers to switches that are used to signal the status of important settings, such as when a control valve is opened or a mechanical interlock is in an unsafe position.
A supervisory signal would result in a "fault" indication on a fire alarm control panel, if not also a specific "zone", functional reference or location for the switch.
The Tamper switches for a fire sprinkler system are located on the main control valves which are located on either side of the backflow preventer for a wet type automatic fire sprinkler system. These switches are wired into the monitoring control system/alarm panel to ensure the valves remain open at all times (or not tampered with.) If the tamper switches are used they will show a supervisory trouble on the panel so the monitoring company or business will know there system is out of service.

The ESP (electronic skid protection) system consists of wheel speed sensors, brake pedal switch, steering angle sensors, yaw rate sensors, etc, etc.The ESP (electronic skid protection) system consists of wheel speed sensors, brake pedal switch, steering angle sensors, yaw rate sensors, etc, etc.
Supervisory control and data acquisition is a type of industrial control sytem. The SCADA can be used to convert sensory data into digital data and sending it to the supervisory system.
- It prevents third party drivers from modifying the operating system kernel.
It turn off the compressor to keep the evaporator from freezing up which can cause system damage.
robust system protection tool
The purpose of credit card protection is to protect the user of a credit card. If one's card is stolen and questionable purchases are made, an automated system will cancel the credit card and alert the user.
Voltage transformer or potential Transformers are used in conjunction with Current transformers for metering and protection purpose in HT and LT power system.
The purpose of a leak detection pump pressure switch is to immediately alter the system to pressure drop. These are most commonly associated with seal or valve failure.
