Pre-Action Fire Alarm Valve For Sensitive Fire Protection

Dual-Trigger Water Discharge: The system only releases water when both the fire detection system is activated (smoke or heat) and a sprinkler head breaks, minimizing the risk of accidental water damage.

Automatic Switch from Dry to Wet: Maintains low-pressure gas in the piping under normal conditions, then charges water to convert the system to wet status upon fire detection.

Intelligent Fire Alarm Notification: Provides immediate alerts to operators when the system activates, ensuring faster response compared to standard dry-type sprinkler systems.

Protection for Sensitive and Extreme Environments: Ideal for areas sensitive to water damage (libraries, archives, server rooms) and adaptable to both freezing temperatures and high-heat conditions.

Integrated Fire Protection Components: Works with pre-action valves, wet alarm valves, signal valves, solenoid valves, hydraulic bells, and pressure switches for reliable and coordinated fire suppression.

Target Application Scenarios

Sensitive Asset Protection: Ideal for areas where accidental water discharge could cause severe damage, such as libraries, archives, museums, and document storage facilities.

Data & IT Centers: Perfect for server rooms, data centers, and computer facilities where water damage must be strictly avoided.

Extreme Temperature Environments: Suitable for regions with freezing winters or high-temperature conditions, as the system remains dry under normal conditions and prevents pipe freeze or false discharge.

Critical Commercial and Industrial Facilities: Can be applied in laboratories, control rooms, and other high-value or high-risk facilities requiring precise and reliable fire suppression.

Dual Protection Scenarios: Works in situations that require both dry- and wet-type protection, ensuring safety in multi-hazard environments.

 

Core Components

 

The Pre-Action Fire Alarm Valve System integrates multiple components to ensure reliable and intelligent fire protection:

Pre-Action Valve: Controls water flow and switches the system from dry to wet status upon fire detection.

Wet Alarm Valve: Triggers waterflow alarms when the system is activated.

Signal Butterfly Valve: Provides remote control and signaling of the system status.

Solenoid Valve: Electrically actuated valve enabling rapid response to detection signals.

Hydraulic Bell / Waterflow Alarm: Provides audible and visual alert when water starts flowing.

Pressure Switch: Monitors system pressure and triggers alarm in case of abnormal conditions.

Together, these components form a coordinated system that prevents accidental water discharge, enhances fire suppression efficiency, and ensures protection for sensitive or critical environments.
