What is the function of detection devices in a deluge system?

In a deluge system, the primary function of detection devices is to identify the presence of a fire and subsequently actuate the deluge valve. Deluge systems are designed for high-hazard areas where rapid fire spread is a significant concern, and they rely on detection devices to ensure that water is released from all open sprinklers simultaneously in the event of a fire.

When these detection devices sense smoke, heat, or flames, they send a signal to the deluge valve to open, allowing water to flow through the entire system. This quick response is crucial in controlling flames and minimizing fire damage.

While manual activation of the sprinklers, monitoring water pressure, and operating alarms are essential components of fire protection systems, they do not define the specific action of detection devices within a deluge system. Therefore, the detection devices’ critical role lies in their ability to detect fire conditions and activate the deluge system effectively.
