D5-Evo & D10 Interlock Wiring Diagram
Detailed wiring diagram for configuring two Centurion operators in an interlock (mantrap/airlock) arrangement. Covers relay connections, loop detector integration, emergency override wiring, and testing sequences for high-security gate installations.
Technical Specifications
Interlock Security Features
The interlock/mantrap configuration provides the highest level of vehicle access security, preventing tailgating and ensuring controlled entry at estates and complexes in Pretoria.
Sequential Operation
Gate 1 must fully close before Gate 2 can open, creating a secure buffer zone that prevents unauthorised entry.
Anti-Tailgating
The interlock system prevents multiple vehicles from entering simultaneously, eliminating tailgating security risks.
Emergency Override
Built-in emergency override ensures gates can be manually operated during power failures or emergencies.

Frequently Asked Questions
What is an interlock or mantrap gate system?
An interlock (also called a mantrap or airlock) is a high-security gate configuration where two gates are wired so that one gate must fully close before the other can open. This creates a secure buffer zone between the two gates, preventing unauthorised vehicles from tailgating through. The vehicle enters through Gate 1, which closes behind them, and only then can Gate 2 open to allow entry. This system is widely used in estate entrances, embassy compounds, and high-security complexes across Pretoria.
Is an interlock gate system suitable for residential use?
Yes, interlock systems are increasingly popular in residential estates and security complexes in Pretoria. While originally designed for high-security commercial applications, they provide excellent security for residential estate entrances by preventing tailgating and ensuring controlled vehicle access. The system can be configured with varying levels of strictness to suit residential traffic flow requirements.
Can visitors override the interlock system?
No, visitors cannot override the interlock system. Only authorised personnel with access to the emergency override key or security control room can bypass the interlock sequence. Visitors must follow the standard entry procedure: enter the buffer zone through Gate 1, wait for it to close, and then be granted access through Gate 2 by the security guard or access control system. This ensures maximum security at all times.
What happens to the interlock gates during a power failure?
During a power failure, the interlock system relies on battery backup power for both gate operators. If batteries are charged, the system continues to function normally. If battery power is also depleted, the emergency manual release key allows both gates to be opened manually. It is critical that both operators have adequately charged batteries, and we recommend a solar backup system for properties in Pretoria experiencing frequent load shedding.
Can the interlock system work with access control and intercoms?
Yes, the interlock system integrates seamlessly with access control systems, intercoms, loop detectors, and CCTV. Loop detectors in the buffer zone detect vehicle presence, the intercom allows communication with the guardhouse, and the access control system can automate the Gate 2 opening sequence once the vehicle is verified. This creates a comprehensive security solution for estates and complexes in Pretoria.
