What is the function of a flow switch in a fire sprinkler system?

The function of a flow switch in a fire sprinkler system is primarily to detect water flow and activate alarms. This component is essential for the operation of fire protection systems, as it monitors the flow of water through the pipes. When a fire occurs and the sprinkler heads are activated, the flow switch senses the movement of water. In response, it sends a signal to the fire alarm panel indicating that water is flowing through the system, which is a critical indication of activation.

This activation is important for alerting occupants in the building and the fire department, allowing for a quick response to the fire. The flow switch plays a crucial role in enhancing safety and ensuring the effective operation of the sprinkler system during an emergency. Therefore, its ability to detect water flow and trigger alarms is vital for the overall effectiveness of fire suppression measures.
