875572 Range Guard Manual Remote Release

The Range Guard WK-875572-900 Manual Remote Release is a fire suppression pull station assembly that allows remote manual activation of Range Guard kitchen fire suppression systems from a safe location outside the immediate fire hazard area. Includes cable housing and all mounting hardware for wall installation, providing a complete fire suppression system pull station solution for NFPA 96-compliant manual activation capability in commercial kitchen environments.

The fire manual pull station is a critical life-safety component for any kitchen fire suppression system. NFPA 96 requires that a manual means of system activation be installed in the path of egress from the kitchen — so that staff can activate the Range Guard system while safely evacuating rather than requiring them to remain in the fire zone to initiate suppression. The WK-875572-900 provides that manual activation point, with cable housing that routes cleanly from the pull station location to the Range Guard universal control head or compatible release module.

For fire protection contractors completing Range Guard system installations or replacing worn manual release hardware during service, the WK-875572-900 is the OEM fire suppression pull station for Range Guard systems. It is identified in the range guard installation manual as the approved manual activation component for the range guard system and must be installed per the range guard fire suppression system manual placement requirements to maintain UL 300 compliance. A pull station guard is available separately for installations where tamper protection is required.

Placement Requirements

Per NFPA 96, the manual pull station must be located in the path of egress from the kitchen — accessible from the exit route without requiring the operator to pass through the fire hazard zone. Mount the WK-875572-900 at a height accessible to all kitchen staff, clearly identified with fire suppression pull station signage. The range guard installation manual specifies maximum cable lengths from the pull station to the control head — verify the routing distance is within the approved specification before finalizing the installation location.

Cable Routing

Route the cable housing from the pull station to the Range Guard control head per the range guard fire suppression system manual cable routing requirements. Avoid running cable through areas subject to damage from kitchen equipment, foot traffic, or heat. Secure the cable housing at regular intervals to prevent sag or movement. Verify cable tension and pull station release function during system commissioning.

Semi-Annual Inspection

During NFPA 17A and NFPA 96 semi-annual inspections, verify the pull station cable is intact, the release mechanism moves freely, and the pull station guard (if installed) is present and functional. Test the pull station release function using the Range Guard-specified test procedure without triggering a live system discharge. Document the test in the fire suppression system inspection record.

Is a pull station guard required with the WK-875572-900?

A pull station guard is required where accidental activation by unauthorized personnel is a concern — particularly in public-facing kitchen areas. The pull station guard accessory is available separately and mounts over the WK-875572-900 housing. In staff-only kitchen environments, a guard may not be required but is recommended as best practice to prevent nuisance activations.

Can this pull station be used with Amerex or Pyro-Chem systems?

No. The WK-875572-900 is specifically designed and listed for Range Guard kitchen fire suppression systems and compatible Range Guard control heads. Amerex KP and Pyro-Chem systems use their own OEM fire suppression pull station hardware. Always match pull station hardware to the system manufacturer to maintain UL 300 compliance and ensure correct cable tension and release geometry.

What is the maximum cable length for the pull station installation?

The maximum cable length is specified in the range guard installation manual for each system configuration. Exceeding the maximum cable length increases friction in the cable housing and can prevent a clean pull station release — potentially preventing system activation in an emergency. Verify the pull station location and cable routing length against the range guard fire suppression system manual before finalizing the installation.
