fire Alarm Check Valve

Alarm Check Valve Summary

An Alarm Check Valve (ACV) is a key component in a wet pipe fire sprinkler system. It prevents backflow and activates an alarm when water flows due to a sprinkler activation.

How It Works:

🚰 Normally Closed – Holds water under pressure.
🔥 Opens During Fire – When a sprinkler activates, water flows through.
🔔 Triggers Alarm – Sends a signal to alert fire response teams.

Key Features:

✔ Prevents Backflow – Ensures water only flows one way.
✔ Delayed Alarm Option – Reduces false alarms from pressure fluctuations.
✔ Works with Sprinkler Systems – Common in buildings and warehouses.

Common Applications:

🏢 Office buildings & commercial spaces
🏭 Factories & warehouses
🛒 Malls & shopping centers

Maintenance Tips:

⚠ Check for clogs & corrosion regularly.
⚠ Ensure alarm activation works properly.
⚠ Follow NFPA 13 standards for inspection & testing.
