ELV explained

What is ELV (Extra Low Voltage)?

ELV systems operate at low voltages (typically under 50V) and form the intelligent nervous system of a modern building — handling safety, security, communication, comfort and energy.

The nerve center of modern buildings

One connected ecosystem

Instead of many isolated systems, ELV integration brings fire, security, communication and automation together so a building can sense, respond and optimise itself.

Because building technologies today are more business-driven than research-oriented, they benefit from advances across the wider tech industry. A well-designed ELV backbone lets you adopt those advances without ripping and replacing — the systems simply plug in.

What ELV covers

Seven systems, one platform

Each one is a discipline of its own. Run over a shared backbone, they behave as a single system.

CCTV & Security

Surveillance cameras, access control and intrusion alarms.

Fire Alarm Systems

Smoke detectors, alarm panels and emergency alerts.

Public Address & Voice Evacuation

Announcements and emergency communications.

Data & Structured Cabling

LAN, Wi-Fi and telephone systems.

Audio-Visual Systems

Meeting-room screens, speakers and conference tech.

Home / Building Automation

Smart lighting, IoT and motorized curtains.

BMS (Building Management)

HVAC, lighting and energy monitoring — the supervisory layer that ties the other six together.

Building Management Systems

From sensor to supervisor

A modern BMS connects field devices to cloud supervision through open protocols (BACnet, Modbus, LON, M-Bus) — giving you centralised control of every building service.

Keyan designs BMS architectures on platforms such as Tridium Niagara and iSMA Controlli — spanning multi-site supervision down to individual I/O modules, control valves and meters.
