Equipped with ranges, broilers, fryers and a myriad of other high temperature cooking appliances, no other environment demands proper fire protection more than today’s modern cooking facilities.

The Kidde WHDR system is specifically designed for the challenging demands posed by cooking applications. By offering one of the most flexible system configurations in the industry, Kidde provides efficient, economical protection for all types of cooking facilities and design layouts. Our customised approach allows you to specify the type of detection, control and cylinder sizes to fit your application. Investing in a Kidde WHDR system guarantees more than just code compliance – including UL300, NFPA 96 & 17A and AS3772 – it provides automatic, round the clock protection from the devastating consequences of fire.

How the WHDR™ system works

1. Fire is detected by the Kidde mechanical link, or electric Detect-A-Fire®, or the system is manually activated by a remote pull station.
2. The XV™ Control System simultaneously actuates up to 20 pressurized agent storage containers and provides microswitch contacts to perform other shutdown or building functions.
3. 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.
4. The Kidde APC agent discharges from strategically positioned nozzles protecting the hood, duct and appliances. PC agent quickly suppresses the flames and forms a protective layer that not only extinguishes the fire, but also prevents re-ignition
