DALI Applications & LCM Connections - 111

In a modern lighting environment with many demands in lighting control, LCM Connection Details
the need to provide a simple cost effective means of control with one
commonly accepted lighting protocol has seen the rapid growth of the Emergency Key Network Network Network
DALI (Digital Addressable Lighting Interface). This has led to the downturn Switch Test Facility Beldon 2 Core or CAT 5 Beldon 2 Core or CAT 5 Beldon 2 Core or CAT 5
in what were the protocols used in the industry with no common interfacing, 230V Mains In
analogue 1-10V and DSI (Digital Serial Interface) systems. 230V Mains In 230V Mains In

The concept is to use DALI as a “sub system” to a building’s lighting 1 Max of 4 PIRs
system. Each “DALI gateway” has a maximum of 64 individual addresses Common
that can be distinguished within its group. per LCM
DALI sub systems are not excluded from centralised lighting control 4
systems, but can be integrated into a fully addressable control system with Orange & Orange/White Brown & Brown/White
the use of a Canbus protocol which connects it to other sub systems and Brown & Brown/White Green & Blue/White
other areas of the project. Blue & Blue/White Blue & Blue/White
DALI control wiring must follow the cable size and distances shown in the Orange & Orange/White
table below. The connection of DALI products are not polarity dependent.
No termination resistors are required, dimming subject to lamp and Ceiling/Floor Modular Wiring Solution

Up to 100 metres 0.5mm²

100-150 metres 0.75mm²

Above 150 metres 1.5mm²

The DALI control pair may be run either in or along side the mains cabling DALI Classroom Solution
as it is rated at the same insulation as the power cables. The maximum
voltage drop on a DALI line must not exceed 2V.
DALI products available to our customers include DALI 64 address
modules, DALI 3 channel switching relay modules, DALI pluggable 10 way
LCMs both Master and Slave versions, DALI PIRs and DALI Scene Plates.
