PCL-460 Tank 551193 for Pyro-Chem

The Pyro-Chem PCL-460 (P/N 551193) is a mechanical control head for Pyro-Chem wet chemical fire suppression systems, designed for use with 4.6-liter cylinder configurations. Like the PCL-600 (551196) for 6-liter cylinders, the PCL-460 provides reliable actuation through cable or fusible link triggers — initiating system discharge when the thermal detection line releases tension from a fusible link melt or when a remote manual pull station is activated. The PCL-460 is the correct control head for the 4.6-liter capacity Kitchen Knight II configurations specified in the pyro chem pcl manual.

The Pyro-Chem PCL series covers the full range of Kitchen Knight II cylinder sizes — from the PCL-165 for smaller installations through the PCL-350, PCL-460, and PCL-600 for progressively larger kitchen configurations. The pyro chem pcl 350 ul 300 certification and pyro-chem pcl 350 flow points documentation confirm the design basis for the entire PCL series. The 551193 PCL-460 is the specific control head for 4.6-liter cylinders and cannot be substituted with a control head from a different cylinder size without voiding the UL 300 listing of the complete system assembly.

For fire protection contractors managing Pyro-Chem kitchen fire suppression system service, keeping the PCL-460 in your pyro chem supply inventory alongside the PCL-600 ensures both common 4.6-liter and 6-liter system configurations can be serviced or replaced without delay. Authorized pyro chem distributors carry the complete PCL series with the full pyro chem price list pricing for volume procurement. The pyro chem kitchen knight manual provides detailed installation and service specifications for the PCL-460 control head.

Semi-Annual Functional Test

Per NFPA 17A and NFPA 96, the PCL-460 must be functionally tested at every semi-annual inspection. Verify the release mechanism cycles completely, the nitrogen actuation cartridge is fully charged and correctly seated, and all auxiliary switch functions operate correctly for gas valve shutdown and alarm outputs. Any binding, sluggishness, or switch failure is an immediate red-tag deficiency. Document in the fire suppression system inspection record. The pyro chem kitchen knight manual provides the complete semi-annual inspection checklist for PCL-series control heads.

Nitrogen Cartridge Verification

Verify the nitrogen actuation cartridge weight meets the minimum specification in the pyro chem pcl manual at every inspection. A depleted or improperly seated cartridge will prevent system actuation. Replace the cartridge if below the minimum weight threshold — available through authorized pyro chem supply channels.

Can I use the PCL-460 on a 6-liter system?

No. The PCL-460 is sized and calibrated for 4.6-liter Pyro-Chem cylinder configurations. The PCL-600 (551196) is the correct control head for 6-liter systems. Using the wrong PCL model on a different cylinder size voids the UL 300 listing. Verify the correct control head using the pyro chem pcl 350 manual or pyro chem kitchen knight manual for your specific system configuration.

Where can I find the pyro chem pcl-350 documentation for reference?
