Range Guard Cable Tension Block Assembly A+ 9197220

The Range Guard 9197220 Cable Tension Block Assembly is used in Range Guard A+ kitchen fire suppression systems to maintain proper cable tension between manual pull stations and the control head. Correct cable tension throughout the detection and actuation cable network is essential for reliable mechanical activation during an emergency discharge — too little tension allows cable slack that delays or prevents system activation, while excessive tension can cause nuisance trips or fatigue the cable prematurely. The 9197220 provides the mechanical means to set and maintain the correct tension specification throughout the cable run.

The Range Guard A+ system uses a mechanical cable network connecting the fusible link detection line, the manual pull station, and the control head into a single integrated actuation circuit. The cable tension block assembly is installed at strategic points in this network to manage cable routing changes and maintain consistent tension across the full cable run. In commercial kitchen installations where the cable must navigate multiple direction changes around cooking equipment and hood structures, the 9197220 ensures each cable segment is correctly tensioned despite the routing complexity.

Available through authorized Range Guard distributors as part of the Range Guard fire suppression system parts catalog. Semi-annual NFPA 17A and NFPA 96 inspection must verify the 9197220 cable tension block is securely mounted, the cable passes through the block correctly, and the tension is within the specification in the range guard fire suppression system manual. A cable tension block showing corrosion, physical damage, or incorrect tension is an immediate inspection deficiency. Document in the fire suppression system inspection record.

At every semi-annual NFPA 17A and NFPA 96 inspection, verify the 9197220 cable tension block assembly is securely mounted and the cable is routed correctly through the block without kinking or abrasion. Check cable tension per the range guard fire suppression system manual tension specification. Inspect the block body for corrosion or physical damage. A tension block that allows cable slippage or shows mechanical damage must be replaced immediately — incorrect cable tension is a fundamental Range Guard A+ system reliability deficiency. After any system discharge, inspect the full cable network including all tension block assemblies before re-arming the system. Document in the fire suppression system inspection record.

How do I verify correct cable tension in a Range Guard A+ system?

Cable tension must be set and verified per the range guard fire suppression system manual specification for the A+ system configuration. The manual specifies the correct tension measurement method and acceptable tension range for each cable segment. Using a cable tension gauge is the recommended approach for precise verification. Contact authorized Range Guard distributors for the Range Guard A+ system manual if you do not have a copy on file.

Can the 9197220 be used in non-A+ Range Guard systems?

The 9197220 is specified for Range Guard A+ systems. Other Range Guard system configurations may use different cable management hardware. Verify the correct component for your specific Range Guard system version using the range guard fire suppression system documentation before installation.
