The KRS-50 Control Box (Figure 1) is a cost-effective, robust control unit used to actuate up to five agent storage cylinders on a Kidde WHDR wet chemical fire suppression system for commercial cooking operations.
The KRS-50 can be operated via a single detection line with up to 40 fusible link and/or thermo bulb link heat detectors or via a Kidde in-line remote manual pull station. Upon operation, the KRS-50 discharges the system CO2 cartridge, pressurizing the actuation line and System Valve Actuators (SVA) mounted on the cylinder valve(s). The SVA(s) open the cylinder valve(s), discharging the WHDR system wet chemical suppression agent. A second mechanical cable is used to concurrently close the gas supply valve, shutting off fuel to the appliance(s).
The KRS-50 is UL and ULC listed and includes one System Valve Actuator and two CO2 actuation cartridges (for test and final set-up).
