Cable Termination inside Panel Access Control System

Cable Termination inside Panel Access Control System

Access Control System (ACS) Cable Termination:
Components typically involved:
Door Controllers: The devices responsible for controlling the locks based on inputs (e.g., card readers, biometric sensors).
Card Readers: Devices for reading access cards, PIN codes, biometrics, etc.
Locks: Electric locks that are controlled via the ACS.
Power Supply: Provides the necessary voltage for the controllers and other components.
Input and Output Devices: E.g., sensors, exit buttons, or alarms.
Cable Termination Steps:
Power Wiring:
Use proper gauge wire for the DC power supply to ensure minimal voltage drop.
Twisted-pair wires should be used for signal transmission to reduce electromagnetic interference.
Terminate power cables (12V or 24V DC) to the power terminals of the door controllers and any auxiliary equipment (e.g., electric locks).
Signal Wiring:
Signal wires from card readers, door sensors, or exit devices should be labeled for easy identification.
Use shielded cables (if necessary) for long cable runs or in areas with high electrical noise to prevent signal degradation.
Terminate the wires at their corresponding input/output terminals in the panel, ensuring no loose connections.
Relay/Output Wiring:
Connect the relay contacts from the door controllers to actuators (locks, turnstiles, gates) using appropriate gauge wiring.
Ensure the wiring to alarm outputs is securely connected and that the alarm devices (e.g., sirens, strobes) are properly powered.
Wire Management:
Neatly organize the wires using cable ties or cable trays to prevent tangling or short circuits.
Leave some slack in the cables for maintenance, but do not overextend them.
Proper grounding of cables and equipment is essential to avoid electrical surges and damage to sensitive components.
