ELV systems: master clocks, IPTV and building infrastructure
ELV stands for Extra Low Voltage — the building systems that run on low-voltage signals rather than mains power, such as data networks, CCTV, PA, access control and clocks.
We supply and install these systems as a package for buildings, working with main contractors and consultants on drawings and BOQs.
What we supply
- Master clock / GPS IP clockOne accurate time source for all clocks in a building.
- IPTV systems
- Public address systemsSee audio visual and PA.
- Structured cablingData, voice, Wi-Fi and fibre — see structured cabling.

How a master clock system works
A master clock takes accurate time from GPS satellites and sends it over the IP network to every slave clock in the building. Every clock then shows the same time, and no one has to reset them after a power cut — useful in hospitals, schools, airports and offices.
Typical applications
