Automatic Wet Alarm Valve Sprinkler System
A wet alarm valve is a type of alarm check valve in a wet sprinkler system that uses water flow to trigger audible alarms, such as a water motor gong or electric alarm.
It is a one-way valve that prevents water from flowing back into the supply line, and when water flows through it due to a sprinkler activating, it activates a local waterflow alarm.

How Automatic Wet Alarm Valve Sprinkler System Works
1. One-Way Flow:
The valve is designed to allow water to flow into the sprinkler system but prevents it from flowing back out into the water supply.
2. Water Flow Activation:
When a sprinkler activates, the water flow opens a flap or clapper in the valve.
3. Alarm Activation:
This water flow also operates a trim assembly connected to the valve, which includes a delay device to prevent false alarms from minor pressure fluctuations.
4. Alarm Sounding:
The water then actuates a water motor gong (a mechanically powered alarm) or sends a signal to an electrical alarm system, which sounds an audible alarm.

FAQ
Q: How does the Automatic Wet Alarm Valve Sprinkler System prevent false alarms from pressure surges?
A: A bypass line with a restrictor and a retard chamber delays the alarm signal; transient pressure spikes equalise across the clapper without lifting it, so only sustained flow (≥1 sprinkler) triggers the bell.
Q: Can one wet alarm valve serve multiple floors?
A: Yes-provided the floor area does not exceed the valve's rated flow (common sizes 500–2 000 L/min) and static pressure at the most remote sprinkler remains ≥0.5 bar above the valve set-point
