What is a tamper switch in a sprinkler system?

Flow switches detect water movement or drop in pressure, and activate alarms. Tamper switches detect when a sprinkler valve has been partially to fully closed and usually activates a trouble signal at the control, although some cities require them activate alarms.

People also ask, what is a flow switch used for?

A flow switch is a device that monitors the flow of air, steam or liquid. It sends a "trip signal" to a different device in the system, such as a pump. The flow switch can indicate to the pump to shut off or to turn on.

How does a tamper switch work?

The tamper switch features an actuating unit, usually a lever or cable with a resting position. When the valve closes, the actuating unit breaks an electrical circuit which triggers a signal. Think of it like a light bulb: when the light switch is on, a circuit is formed and the bulb shines brightly.
