How the System Works?

1. Fire is detected activating the XV TM Control System (or the manual pull station is actuated)… causing the cylinder valve to open.
2. Pressure stored in the cylinder propels the wet chemical agent through the system piping and out of strategically located nozzles. The Kidde WHDR System automatically shuts down the power source to appliances removing the heat.
3. The wet chemical agent knocks down flames quickly and forms a protective layer that suppresses fire and prevents fire re-ignition.

How the Agent Works?

The Kidde WHDR system uses Kidde APC wet chemical agent, which extinguishes fire by:

• Saponifying the surface grease (converting it into combustion-resistant soap)
• The cooling effects of water vaporization
• Interrupting the chemical chain reaction of combustion Kidde APC wet chemical agent is proven to be the best suppressant for quick knock-down and prevention of re-ignition of flame.
