Overview

The compact, Pro Four-Cell Round is ideal for use in medium- tolong-throw, pendant style applications. The luminaire is suppliedwith half-inch and M10 captive nut plates for connecting threadedrod, providing multiple hanging options. Manufactured from high-grade, powder-coated aluminum and steel, the luminaire is entirelyconvection cooled for silent operation.

The Pro Four-Cell Round includes an onboard power supply andconnects directly to a 100–240 V mains supply. Intensity control isachieved with a direct, wired-DMX connection to the luminaire’sRJ45/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 fromthe maintained supply. There is no control of the luminaire via wired-DMX until normal utility power is restored to the sense input.
