Easy installation
Save up to 70% time – install on the first try
No more questions about “which wire goes where.” With ready-made wiring diagrams, the technician follows a clear recipe – not a guessing game. Fast, safe and correct every time.
Fewer errors
Everything is carefully marked and thoroughly tested. You avoid confusion between night lock, elbow switch and function input. The system is designed to eliminate human error – and gives you full control and maximum security, every time.
One solution for all door environments
Double lock? Automatic opener? Emergency release in case of fire? This box handles it all:
• Standard access with card or key
• Automatic opening for the disabled (elbow switch)
• Night security with extra lock
• Fire-proof emergency exit – in line with DSB's safety requirements
Maintenance without headaches
Standardized solutions and clear marked. No hidden links or creative shortcuts. You get a system that is easy to understand – and just as easy to maintain, even many years after installation.
