ETC/Elec Theatre Controls DEBC-6
6-Output DMX Emergency Bypass Controller

OUR PART #  DEBC-6


The DMX Emergency Bypass Controller (DEBC) from ETC 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.

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.

SAFETY NOTES:

  • When using electrical equipment, basic safetyprecautions should always be followed including the following:
  • READ AND FOLLOW ALL SAFETY INSTRUCTIONS.
  • Do not use this equipment for other than its intended use.

The DMX Emergency Bypass Controller provides a simple and cost-effective solution for control bypass of LED houselight systems in emergency lighting applications. The DMX Emergency Bypass Controller uses a single contact-closure input to bypass the DMX control signal and drive all connected loads to full. Optionally, selected fixtures can be controlled using the snapshot setting.

  • Applications:
    • DMX houselights
    • Permanently-installed, DMX-controlled LEDs
    • Theaters
