About This Product

When a dam releases water or a hydroelectric power plant starts generating electricity, the amount of water downstream from the outlet increases. Discharge warning devices prevent danger by notifying people downstream from the discharge point of the discharge using broadcasts, sirens, etc. The speaker has a function that detects whether sound is produced or not, and confirms that it was actually broadcast.

■Product features

■Applicable location

Dams and power plants with water discharge facilities, etc.
