What key function does a flow switch perform in a sprinkler system?

A flow switch serves a critical role in the operation of a sprinkler system by detecting the movement of water through the pipes. When water begins to flow, the flow switch activates and sends a signal to the fire alarm system, initiating alarms to alert occupants and responders of the potential fire scenario. This immediate response is essential in ensuring that everyone is informed of the situation, allowing for timely evacuation and response to the fire.

The function of the flow switch is pivotal for fire safety as it ensures that alarms are triggered as soon as there’s a breach in the system necessitated by water flow, indicating an active sprinkler discharge likely due to a fire. This proactive measure assists in mitigating risks during a fire emergency.
