Products Description
Alarm Valve Assembly
forede ® Alarm Valve Assembly is a critical component in fire protection systems, designed to detect and respond to fire emergencies automatically. It integrates multiple functional elements to ensure rapid water release and alarm activation, making it essential for safeguarding buildings and occupants.
The assembly consists of several key parts:
Wet Alarm Valve: The main valve that remains closed during standby but opens when fire is detected, allowing water to flow.
Retard Chamber: Delays the alarm signal slightly to prevent false triggers from minor water pressure fluctuations.
Water Alarm: Sends an alert to the control center when water flows through the system.
Pressure Switch & Flow Meter: Monitors system pressure and water flow, ensuring proper operation.
Closed Head Sprinkler: Contains a heat-sensitive element (e.g., glass bulb) that bursts at high temperatures, releasing water.

FAQ
1.What is an Alarm Check Valve (ACV)?
A mechanical valve that prevents backflow and detects water flow to trigger fire alarms in wet sprinkler systems.
An ACV includes an alarm port and flow-sensing mechanisms to trigger alarms, while a standard check valve only prevents reverse flow.
3. How does a water motor gong operate?
Water flowing through the alarm port drives a turbine, which strikes a bell to produce an audible alarm.
4. Can an ACV operate without electricity?
Yes, the mechanical water motor gong works independently of electricity, ensuring reliability during power outages.
3. How often should an ACV be tested?
Monthly alarm tests and annual inspections for corrosion, leaks, and proper clapper movement.
