Why 2-Door Interlocking Units?

2-door interlocking units are essential for secure access control, ensuring that only one door can be open at a time-commonly used in security mantraps, cleanrooms, banks, and high-security offices across South Africa. By managing entry/exit logic, these units enhance site safety and prevent unauthorized passage or tailgating.

Selecting the Right 2-Door Interlock Unit

Selection Tips

• Door Type: Confirm if used with magnetic locks, electric strikes, or other actuators.
• Fail-safe/fail-secure requirement: Ensure unit meets site safety/redundancy needs.
• Control Input: Identify whether standalone (keypad logic) or integration with alarm/panel is needed.
• Power Supply: Most units require 12V or 24V DC-Communica supplies compatible power sources.
• Environmental rating: Indoor models are standard; outdoor housings may need weatherproofing.

Wiring Example (Simple 2-Door Relay Interlock)

   [PSU +12V]---+---[Door 1 Lock]---[NO Relay1]
                |         |
                |         +---[COM Relay1]---GND
                |
                +---[Door 2 Lock]---[NO Relay2]
                          |
                          +---[COM Relay2]---GND

Both relays are controlled by the interlock logic to ensure only one lock can be energized/opened at a time.
