ETC DMX DEBC-1 Installation Manual

ETC Installation Guide
DMX Emergency Bypass Controller
The DEBC requires that the electrical supply to the lighting fixtures is a normal/emergency source fed by an
upstream transfer switch or other emergency power system. Upon loss of utility power or other event when
egress lighting is needed, a dry contact closure or +12VDC input forces the DMX data link that is feeding
connected fixtures into a bypass state. The bypass state can be defined as "All DMX channels to full" or a
designated emergency setting of each DMX channel to a selected level.

DEBC Types

There are two types of DMX Emergency Bypass Controllers available:
• Single-output DEBC (DEBC-1): Single DMX input, single DMX output
• Six-output DEBC (DEBC-6): Single DMX input, six DMX outputs

Important Safeguards

When using electrical equipment, basic safety precautions should
always be followed including the following:
–READ AND FOLLOW ALL SAFETY INSTRUCTIONS.
–Do not use this equipment for other than its intended use.
–SAVE THESE INSTRUCTIONS.
–All servicing should be performed by qualified personnel only.

Overview

The DMX Emergency Bypass Controller (DEBC) allows
DMX512-controlled fixtures, such as LEDs, to operate as
normal/emergency fixtures by bypassing a single universe of
DMX512 directly to the connected fixtures. This unit is
designed to override the control signals on designated
emergency lighting fixtures that are separately energized
upon loss of utility power.
The bypass is triggered through the onboard contact closure
input, such as in the event of a power outage. The contact
closure may be normally open or normally closed, and is
supplied by an external device. For example, to turn lights on
during a power loss, utilize the ETC Emergency Bypass
Detection Kit (EBDK) or other suitable power sensing device.
The DEBC may also operate as part of a closed-loop fire alarm
system.
