2. Setup and Installation

The AL20-AL Armored Loop is intended for professional installation to ensure proper function and security. The installation process involves mounting the two end housings, one on the door frame and one on the door, and routing the low voltage wiring through the armored cable.

2.1 Components Check

Before beginning installation, ensure all components are present and undamaged:

• Flexible Armored Cable (20 inches)
• Two End Housings (Satin Aluminum)
• Mounting Bracket
• Assorted Mounting Screws

2.2 General Installation Steps (Consult specific lock/device manual for detailed wiring)

1. Preparation: Identify the optimal location on the door frame and door edge for mounting the armored loop, ensuring it does not interfere with door operation.
2. Mounting Bracket Installation: Secure the mounting bracket to the door frame using the provided screws. This bracket typically anchors one end of the armored cable.
3. End Housing Placement: Install one end housing on the door frame, aligning it with the mounting bracket. Install the second end housing on the door edge, ensuring proper alignment with the first housing when the door is closed.
4. Wiring Routing: Carefully route the low voltage power wires from the door frame through the armored cable and into the door, connecting them to the intended locking device. Ensure wires are not pinched or strained.
5. Secure Armored Cable: Securely attach both ends of the armored cable into their respective end housings.
6. Final Fastening: Fasten all components securely using the provided screws. Test the door's operation to ensure smooth movement and proper wire protection.

For specific wiring diagrams and compatibility, refer to the installation instructions provided with your electric lock or access control device.

3. Operation

The AL20-AL Armored Loop is a passive component designed to protect low voltage wiring that passes between a door frame and a door. Once correctly installed, its "operation" is continuous and maintenance-free in terms of active user interaction.

It functions by providing a flexible, armored conduit for electrical wires, preventing them from being cut, pinched, or damaged as the door opens and closes. This ensures uninterrupted power supply to the electric locking device, allowing it to function as intended by its own control system.

4. Maintenance

The AL20-AL Armored Loop requires minimal maintenance. Regular inspection can help ensure its longevity and continued protection of your wiring.

• Cleaning: Periodically wipe down the exterior of the armored loop and end housings with a soft, damp cloth to remove dust and grime. Avoid abrasive cleaners or solvents.
• Inspection: Annually or bi-annually, inspect the armored cable for any signs of wear, kinking, or damage. Check that the end housings are securely fastened to the door frame and door.
• Connection Check: If experiencing issues with the connected locking device, verify that the wiring connections within the armored loop's housings are secure and free from corrosion. (This typically requires professional assistance).

Do not attempt to disassemble the armored cable or force it into extreme bends, as this may damage the internal wiring or the armor itself.

5. Troubleshooting

As a passive component, the armored loop itself rarely "malfunctions." Most issues will stem from improper installation or damage. If the connected electric locking device is not functioning, consider the following:

• No Power to Device:
  • Check the power source for the locking device.
  • Inspect the wiring within the armored loop for cuts, pinches, or loose connections. This may require professional inspection.
  • Ensure the armored loop is not severely kinked or damaged, which could sever internal wires.
• Door Binding/Interference:
  • Verify that the armored loop and its housings are installed in a way that does not obstruct the door's opening and closing path.
  • Check for any physical damage to the loop that might cause it to protrude excessively.
• Visible Damage to Armored Loop:
  • If the armored cable or housings are visibly damaged (e.g., crushed, cut, severely bent), the unit should be replaced immediately to prevent electrical hazards or loss of security.

For complex electrical issues or if you suspect internal wiring damage, it is highly recommended to contact a qualified electrician or security system technician.
