VITM4-2CH
Vitesse Modular 4 - 2 Channel Switching Modules
Overview
The Vitesse modular system is a cost effective method of providing power and control for lighting installations in in-
dustrial, commercial and retail buildings. The system is designed for ease of installation: mains input is connected
using the spacious wiring compartment; control inputs and outputs are pluggable using industry standard connectors.
The modular approach allows for between 4 and 16 luminaires to be connected.
The VITM4-2CH is a two channel, non-dimming distribution box for use in applications that require two independently
switched lighting circuits, or lighting and ventilation circuits. For example this product is ideal for connection to a 2
channel presence detector for separate window row switching. It has two live inputs, a common neutral and two
switch inputs.

Warning. This device works at mains voltage. Be sure to take care when working with electricity.
The box should be fixed on a smooth, flat surface or using drop rod fixings attached to channel nuts.
Ensure that there is easy access to the wiring compartment and all connectors once the box is in-situ.

Switched live turns the lights on and off
Use the cable clamps to secure the wiring or use cable glands (not
supplied). The clamps can be split, and flipped over to clamp
different cable diameters.
Replace wiring compartment cover.
Plug in the luminaires ensuring that the connector latches to the box.

Connecting a detector
CH1 and CH2 plugs are coded.
Ensure that the plugs are
inserted correctly and do not
apply excessive force
Detector lead needs to be ordered separately
from the detector. Order code VITM4-L3-2CH.
Where two detectors connect to a single box a
dual lead is available VITM4-LD3-2CH.

Diagrams show separate switches for each channel. One switch can be used for both channels. For 2 switches set
switch mode on detector to 1 position switch separate, for 1 switch set to 1 position switch together. See detector
installation instructions for further information.
This wiring may also be used for presence override switches.

Applications
2 Channel detectors
The flexibility of using two channels detectors allows the following scenario:
Channel 1 - occupancy and lux
Channel 1 of the detector can be used to switch the Channel 1 luminaires at a preset lux level. These luminaires
are typically situated nearest the windows. The luminaires will also switch with occupancy.
Channel 2 - occupancy only
The inner luminaires, ie those furthest from the windows, are switched with occupancy only.
Switch inputs
One or two manual switches, ie for luminaires on channels 1 and 2, can be used to manually override the lights on
or off, or in the case of absence detection activate the luminaires on entry.
The diagrams below illustrate a typical application.
