Door Entry Systems Lab: Installation, Wiring and Diagnostics

Objectives

The programme introduces the principles, installation and diagnostics of residential door entry systems, from single-family to multi-family configurations, with the integration of auxiliary functions.

• Configuration and commissioning
  • Assembly, wiring and testing of door entry systems.
  • Setting up and functional testing of door releases and stairwell lights.
• Parallel circuits for multiple flats
  • Single/two-family topologies and sequential control logic.
  • Managing interference and separating system branches.
• Stairwell lighting automation
  • Interfacing the door entry unit with a timed stairwell light relay.
  • Integration of audible and visual signals.
• Troubleshooting
  • Fault finding, measurements and restoring operation.
  • Use of technical documentation and wiring diagrams.

Aims

The lab safely replicates real residential installations using photorealistic training modules, protected wiring and a clear separation between low-voltage (12V AC) and mains (230V AC) circuits.

• Understanding systems and components
  • Outdoor/indoor units, power supply, actuators (door release, stairwell light), push buttons and indicators.
  • AC operation of door phones and chimes; 12V–230V interfacing.
• Practical skills
  • Installation and wiring on bench modules with 2/4 mm safety leads.
  • Start-up, testing and diagnostics with simulated faults; multi-unit scenarios and remote control.
• Standards and electrical safety
  • Applying CEI standards for low-voltage installations.
  • Insulation, transformers, galvanic isolation and colour coding to prevent errors.

Conclusion

By the end of the programme, students will be able to:

1. Configure, wire and commission a real door entry system.
2. Build parallel circuits for multiple flats with sequential logic.
3. Integrate door releases and stairwell lighting automation safely.
4. Apply CEI standards and work safely at 12V/230V.
5. Diagnose and repair simulated faults methodically, with proper documentation.

The lab is ideal for technical schools, vocational training centres (CFP) and ITS: it develops theoretical and practical skills for the electrical installation sector and basic home automation.
