Range Guard 24in Actuation Hose 120045 002

The Range Guard 24-inch Actuation Hose (120045-002) is a mission-critical high-pressure component designed to serve as the primary pneumatic link within Range Guard and Industry Guard fire suppression systems. In the sophisticated architecture of a fire safety network, the actuation line is the pneumatic nerve. It is responsible for carrying the high-pressure gas pulse from the Universal Control Head (UCH) or A+ Control Box directly to the System Valve Actuators (SVA) mounted on the agent cylinders.

While traditional fire protection systems often rely on rigid 1/4-inch copper tubing, the 120045-002 offers a superior, flexible alternative. Constructed from high-tensile braided stainless steel, this 24-inch hose is engineered to withstand the instantaneous pressure wave of a nitrogen or CO2 activation cartridge. For fire protection contractors, the 120045-002 is the definitive choice for ensuring a fail-safe connection in the cramped, high-vibration environments of a modern commercial kitchen.

Kinetic Pressure Transmission

When the control head is triggered, it punctures an activation cartridge, releasing a concentrated burst of gas. The 120045-002 must contain and direct this pressure wave toward the cylinder actuators. The internal lining is designed for low friction, ensuring the gas reaches the SVA with minimal pneumatic lag, a requirement for meeting UL 300 rapid-discharge mandates.

Vibration Dampening and Stress Relief

Commercial kitchens are high-vibration environments due to industrial exhaust fans. Rigid copper tubing is susceptible to work-hardening and eventual stress-cracking at flare fittings. The braided stainless steel construction of the 120045-002 naturally provides vibration dampening, protecting the pneumatic circuit from the fatigue that leads to leaks in a stored-pressure system.

Corrosion Resilience in the Grease Zone

Situated behind exhaust hoods, actuation lines are exposed to aerosolized grease. The 300-series stainless steel braid provides a barrier against pitting corrosion, ensuring the hose maintains its burst-pressure rating throughout its decade-long service life.

Overcoming Alignment Challenges

In many retrofits, agent cylinders are mounted in restricted spaces where aligning rigid copper pipe is impossible. The 24-inch flexible reach of the 120045-002 allows for a natural sweep between components, eliminating the need for complex tube bending and reducing the risk of kinking.

Maintaining UL 300 Purity

The Range Guard system is a complete, integrated assembly. The 120045-002 is the specific hose tested for the exact pressures and flow rates of the Karbaloy discharge sequence. Substituting this with a generic hydraulic hose can void the UL listing, leaving the facility owner liable during insurance claims.

Simplified Multi-Tank Manifolding

When protecting large industrial cook lines with multiple cylinders, the 120045-002 simplifies the daisy-chain connection between SVAs. Its flexible nature allows technicians to route the line around obstacles like gas pipes, significantly reducing labor hours on-site.

• Commercial Kitchen Exhaust Plenums: Connecting the control head to cylinders in high-heat zones where flexibility is required for maintenance access.
• Multi-Cylinder Fryer Protection: Providing the pneumatic link for large-scale RG-4 or RG-6 configurations requiring balanced actuation.
• Food Trucks and Mobile Catering: A vibration-resistant solution where the motion of the vehicle would cause traditional copper tubing to snap.
• Institutional Facilities: Ensuring a robust, code-compliant safety infrastructure that passes the most rigorous fire marshal audits.
• Industry Guard Dry Chemical Systems: Fully compatible with Badger's dry chemical systems for paint booths and hazardous storage areas.

The Radius Rule Protocol

When installing the 120045-002, never exceed the minimum bend radius. A kinked hose will restrict the pneumatic pulse. The 24-inch length is designed to provide a smooth, sweeping curve between the UCH and the first cylinder.

Fitting Integrity Audit

During the mandatory 6-month inspection, NPT and JIC fittings must be checked for tightness. A leak in the actuation line is the leading cause of a silent system failure where the control head fires but the agent never discharges.

Braided Exterior Inspection

Check the stainless steel braid for any broken wires. A frayed braid indicates that the hose has reached its fatigue limit or has been subjected to mechanical abrasion. If found, the hose must be replaced immediately.

Grease Accumulation Management

While the stainless steel is corrosion-resistant, heavy buildup can make the hose difficult to inspect. Wipe the hose down with a mild degreaser during semi-annual service to maintain the mechanical response integrity.

Can I use this hose to extend an actuation line beyond 30 feet?

Range Guard specifications allow for a total of 30 feet of actuation line when using a combination of hoses and tubing. Runs longer than this require consultation of the technical manual for pressure-drop and line volume calculations, as it may require a larger activation cartridge.

Is the 120045-002 compatible with Ansul or Amerex cylinders?

No. While fittings might seem similar, the pressure ratings are tuned for Range Guard and Industry Guard systems. Mixing manufacturers is a fire code violation and can result in mechanical failure.

Why is 24 inches the standard length?

The 120045-002 is designed to provide enough slack for cylinders mounted adjacent to a control cabinet. For cylinders mounted directly to the same bracket as the control head, a shorter 7.5-inch hose is often used to minimize excess line volume.
