Light Current Systems Course
Master every major low-current discipline — from fire alarm and access control to structured cabling, CCTV, and building automation — in one comprehensive training programme. You'll build hands-on skills that employers and contractors demand on real job sites. This course takes you from electrical fundamentals all the way through advanced system integration and commissioning.
What you will learn:
You'll start with electrical fundamentals and safety procedures, then move through cable selection, termination techniques, and conductor sizing. From there, you'll cover fire alarm system design, intrusion detection, access control hardware, and structured cabling standards. The course also trains you on IP video surveillance, distributed audio systems, and building automation protocols including BACnet, Modbus, and MQTT. You'll learn to use diagnostic tools, size backup power systems, and produce professional as-built drawings and test reports. By the end, you'll be ready to install, commission, and integrate low-current systems across commercial and institutional projects.
