OEM 1/16 Stainless Steel Cable (500ft) 079653

The Ansul 1/16" Stainless Steel Cable (079653) is a professional-grade OEM actuation component designed to serve as the critical mechanical link in ANSUL AUTOMAN detection and release networks. In a pre-engineered fire suppression system, the cable is under constant static tension, holding the potential energy of the release mechanism in check. The 079653 cable is engineered to transmit the kinetic signal from a melted fusible link or a manual pull station to the control head with zero elongation and maximum reliability.

Supplied in a bulk 500-foot spool, this cable allows technicians to create continuous, splice-free runs across large kitchen hoods and complex industrial plenums. Manufactured from high-tensile, austenitic stainless steel, it is designed to survive the relentless exposure to aerosolized grease and caustic cleaning agents. For fire protection professionals, this cable is the industry standard for ensuring that the trip of a detection device results in an instantaneous, successful system discharge.

7x7 Strand Configuration

The 079653 is constructed in a 7x7 strand pattern (seven strands of seven wires each). This specific geometry provides the flexibility required to navigate tight pulley elbows while maintaining the high axial stiffness needed to prevent cable stretch. In a system where a fraction of an inch of travel determines activation, this low-elongation core is mandatory.

Tensile Strength and Load Capacity

This 1/16" cable is rated to handle significant static loads, with a breaking strength often exceeding 480 lbs. This provides a massive safety margin over the typical 50 to 100 lb tension found in a standard detection line, ensuring the cable will not neck down or snap during the high-torque event of a manual pull or a high-velocity spring release.

Corrosion-Resistant Passivation

Unlike galvanized cables, the 079653 is inherently resistant to micro-pitting caused by the chemical interactions of grease and humidity. The chromium-rich surface layer provides a self-healing barrier, ensuring the cable remains smooth and free of snags that could cause it to bind inside its EMT conduit.

Splice-Free System Integrity

Every splice in a detection line is a potential failure point. The bulk spool allows technicians to pull a single, continuous length of cable. This clean-run protocol is the best practice for reducing friction and ensuring a reliable mechanical response.

Compliance with NFPA 17A and 96

NFPA requires that detection and actuation components be listed and labeled. The 079653 is the specific UL-listed cable for the Ansul R-102 system. Using non-OEM cable from a hardware store is a code violation that can result in red-tags from the Authority Having Jurisdiction (AHJ).

Waste Mitigation and Custom Sizing

The spool format allows for precision field-cutting, ensuring that technicians have exactly what they need for a 10-foot range or a 100-foot multi-tank manifold without the waste of pre-cut lengths.

• Commercial Kitchen Detection Lines: Connecting a series of scissor linkage detectors and fusible links across the cooking line.
• Manual Pull Station Links: Routing the emergency override cable through walls to an accessible exit path.
• Mechanical Gas Valve Actuation: Safeguarding the cable path that triggers mechanical gas shutoff valves located behind heavy equipment.
• Industrial Paint Spray Booths: Providing a reliable mechanical trigger in volatile environments where electrical sensors are prohibited.
• Marine Galleys: Offering a corrosion-proof detection solution for offshore vessels where salt-air exposure is extreme.

De-Burring Conduit Ends

When pulling the cable through EMT conduit, ensure all ends are reamed and de-burred. A jagged metal edge can strip the outer wires, causing the cable to bird-cage and jam inside the conduit during a fire.

Correct Tensioning Protocol

After installation, use a tensioning tool to set the cable to the manufacturer's specified tension. An under-tensioned cable will result in a dead-pull, while an over-tensioned cable can cause premature link failure.

Visual Inspection for Fraying

During every service, technicians must inspect the cable at every pulley. If you see silver dust or broken wire strands, the cable is compromised and the entire run should be replaced using fresh cable from the spool.

Precision Cutting

Use a high-quality cable cutter designed for stainless steel. Standard side-cutters will crush the 7x7 core, making it difficult to thread the cable through the Automan sear.

Can I use this cable for a non-Ansul system?

No. While 1/16" stainless steel is a common size, the 079653 is specifically factory-approved for Ansul R-102 and Piranha systems. To maintain a UL listing, you must use the cable specified in the system's as-built drawings.

How do I know if the cable has "stretched"?

Stainless steel has very low elongation. If your Automan requires constant re-cocking, it usually indicates a pulley has shifted or a link is failing rather than the cable stretching. However, if the cable shows any signs of deformation, it must be replaced.

Is this cable suitable for outdoor use?

Yes. The stainless steel construction makes it highly resistant to rust, making it suitable for outdoor enclosures or coastal installations where saline oxidation is a constant threat.
