What is a tamper switch for sprinkler system?

On a sprinkler system, the tamper switch detects when a sprinkler valve has been partially or fully closed. The tamper switch also sends a signal to the central control. Some fire departments require buildings to have tamper switches activate fire alarms to alert building occupants to vacate.

A good tamper switch allows you to easily perform maintenance on a sprinkler system. It is helpful in seeking out problems before you encounter an emergency. Because of the high-tech nature of tamper switches, it is important to know exactly what you are doing with them. Usually, trained engineers should be the only ones in control of the building's sprinkler system.
