đź”” Sprinkler System Alarm Bell (Water Motor Gong Alarm)
Origin: Fujian, China
🔧 Product Overview
The Water Motor Gong, also known as the Sprinkler System Alarm Bell, is a hydraulically driven audible alarm that functions without any electrical power.
When the sprinkler system is activated—due to fire or pressure discharge—water flows through the alarm body, spinning the impeller which drives the shaft and striker assembly. This motion generates a continuous ringing sound as long as water flow persists, providing an immediate and reliable indication of sprinkler activation.
Built for high reliability and durability, this alarm ensures dependable performance in commercial, industrial, and residential fire protection systems.
