🔔 Sprinkler System Alarm Bell (Water Motor Gong Alarm)
Origin: Fujian, China
🔧 Product Overview
The Water Motor Gong, also known as the Sprinkler Alarm Bell, is a hydraulically driven audible alarm that operates without any electrical power.
When the sprinkler system is activated due to fire or pressure discharge, water passes through the gong body and drives the impeller, causing the shaft and striker assembly to rotate. This movement produces a continuous ringing sound for as long as water flow continues, ensuring immediate notification of sprinkler activation.
Designed for reliability and durability, this alarm provides essential fire warning signals for commercial, industrial, and residential fire protection systems.
