  Product Description

  This four-conductor bell wire is designed for low-voltage control wiring in commercial garage door, overhead door, gate operator, access-control, alarm, and signaling applications.

  The cable contains four individually insulated solid conductors, allowing multiple control functions to be connected through a single wire run. It is especially useful for traditional three-button commercial control stations that require separate conductors for Open, Close, Stop, and Common.

  Supplied on a 500-foot spool, this wire is suitable for professional installers, service companies, commercial door technicians, and facilities that regularly install or repair low-voltage operator controls.

  Product Features

  • Four individually insulated conductors
  • 22-gauge solid-wire construction
  • 500-foot bulk spool
  • Supports multiple low-voltage control functions in one cable
  • Suitable for hardwired commercial operator controls
  • Convenient for long installation runs
  • Easier and cleaner than running multiple separate two-conductor wires
  • Useful for new installations, service work, and rewiring projects
  • Can be cut to the required installation length

  Common Applications

  This four-wire bell cable may be used for compatible low-voltage wiring involving:

  • Three-button Open/Close/Stop control stations
  • Commercial garage door operators
  • Industrial overhead door operators
  • Automatic gate operators
  • Key switches
  • Pull switches
  • Interlock controls
  • Access-control equipment
  • Relays and control modules
  • Alarm and signaling equipment
  • Other compatible low-voltage circuits

  For a traditional three-button control station, the conductors may be assigned to:

  • Open
  • Close
  • Stop
  • Common

  Actual conductor assignments must follow the connected operator’s wiring diagram.

  Compatibility

  This wire may be used with many commercial garage door and gate operators that accept low-voltage hardwired controls.

  Before ordering or installing, verify:

  • Required wire gauge
  • Number of conductors
  • Control-circuit voltage
  • Maximum permissible wire-run length
  • Indoor or outdoor installation requirements
  • Solid-versus-stranded conductor requirements
  • Applicable electrical and building codes

  This product is intended for low-voltage control circuits. It is not intended to carry standard 120V or 240V operator power unless specifically approved and rated for that use.

  Four-Conductor Advantage

  A four-conductor cable allows four separate electrical paths to be routed through one outer cable.

  This is particularly helpful for a three-button control station because Open, Close, Stop, and Common connections can all be completed with one wire run between the station and the commercial operator.

  Using one four-conductor cable can provide:

  • Cleaner installation
  • Fewer individual wire runs
  • Easier routing through conduit
  • Simplified troubleshooting
  • More organized terminal connections
  • Reduced installation time

  Installation Notes

  Disconnect electrical power to the operator before installing or servicing control wiring.

  Route the wire away from:

  • Moving door components
  • Torsion springs
  • Lift cables
  • Chains and sprockets
  • Sharp metal edges
  • High-voltage conductors
  • Hot surfaces
  • Areas subject to physical damage

  Use approved bushings, staples, clips, conduit, and protective fittings as required. Do not crush, sharply bend, or damage the wire insulation.

  Strip only enough insulation to make a secure terminal connection. Loose copper strands are not an issue with solid wire, but exposed conductor should not extend beyond the terminal.

  Label or document conductor colors at both ends of the installation to simplify future service and troubleshooting.

  Indoor and Outdoor Use

  Confirm the cable’s jacket rating before installing it outdoors, underground, in wet locations, or inside exterior conduit.

  Standard bell wire is commonly intended for protected indoor low-voltage installations. Outdoor, underground, plenum, riser, or wet-location applications may require a cable with a specific environmental rating.

  The use of conduit alone does not automatically make indoor-rated wire suitable for every exterior or wet-location installation.

  Package Contents

  • One 500-foot spool of 22-gauge, four-conductor solid bell wire

  Control stations, operators, conduit, wire connectors, staples, terminal blocks, relays, and other installation materials are not included.

  Safety Information

  Use this wire only within its approved voltage, current, temperature, and environmental ratings.

  Do not connect low-voltage bell wire directly to incoming line voltage.

  Always follow the garage door or gate operator manufacturer’s wiring diagram. Incorrect wiring may cause control failure, unintended door movement, equipment damage, or an unsafe operating condition.

  Installation should be completed by a qualified garage door, gate, access-control, or electrical technician.
