Overview

The Pro Four-Cell Square provides medium- to long-throwillumination and is ideal for use in locations where hanging spaceis limited. The Pro Four-Cell Square is equipped with a yokeoffering maximum focusing flexibility. Manufactured from high-grade, powder-coated aluminum and steel, the luminaire is entirelyconvection cooled, meaning zero noise emission.

The Pro Four-Cell Square luminaire connects directly to a mainssupply and is supplied complete with an onboard power supply.Intensity control is achieved with a direct, wired-DMX connection tothe luminaire’s RJ45/etherCON connectors.

ArcSystem has been specifically developed for auditorium lightingapplications where high-quality, extremely accurate and smoothdimming is required. The use of onboard device management in thedriver allows all luminaires to be addressed remotely, ensuring fastand simple installation.

Emergency Connection

A dual-input emergency version of this luminaire is available. Emergency luminaires require two line-voltage inputs that perform the following functions:

• Normal power/emergency power
• Normal power sense input

The sense input is used to detect whether normal utility power has been lost. This will force the luminaire on at 100% intensity running from the maintained supply. There is no control of the luminaire via wired-DMX until normal utility power is restored to the sense input.
