How Kidde WHDR Wet Chemical Systems Work

  1. Fire is detected by the Kidde mechanical link, or electric Detect-A-Fire (DAF), or the system is manually activated by a remote pull station.
  1. The XV Control System simultaneously actuates up to 20 pressurized agent storage containers, shuts down fuel and power sources to the appliances and activates the building fire alarm.
  1. Kidde APC wet chemical agent, designed specifically for the challenges posed by oil and grease in a kitchen environment, is propelled through the system piping by the stored pressure container.
  1. The Kidde APC agent discharges from strategically positioned nozzles protecting the hood, duct and appliances. APC agent quickly suppresses the flames and forms a protective layer that not only extinguishes the fire, but also prevents re-ignition.
