1.01	DMX Emergency bypass CONTROL
A.	Where required to trigger special-purpose lighting presets and bypass normal lighting controls during emergency or panic situations, the bypass means shall be the DMX Emergency Bypass Controller (DEBC) as manufactured by ETC, Inc., or equal
B.	Functional
1.	The DMX Emergency Bypass Controller shall be capable of overriding a single universe of ANSI E1.11–2008, USITT DMX512-A control signals from “Normal” to “Bypass” when a trigger signal is detected via a contact closure trigger input
a.	The DMX Emergency Bypass Controller shall output to a single DMX output or up to six optically-isolated DMX outputs
b.	The DMX Emergency Bypass Controller shall poll the bypass trigger input after a power loss and react upon start up
c.	The default or recorded preset shall be recalled immediately on restart if the trigger is also applied at restart
d.	Controllers that do not support E1.11–2008 compliant DMX communication shall not be acceptable
2.	The DMX Emergency Bypass Controller shall be capable of recording a single DMX preset (snapshot) of 512 channels for recall during “Bypass” mode
3.	The DMX Emergency Bypass Controller (DEBC) shall have internally accessible, labeled DIP switches for configuration of:
a.	DMX Record Mode 
1)	All 512 channels (default)
2)	Selected channels, snapshot
b.	Contact input type
1)	Normally open (default)
2)	Normally closed
c.	Wait Time for Restore incoming DMX (bypass trigger removed)
1)	0 Seconds (default)
2)	10 Second Wait
3)	30 Second Wait
4)	10 Minute Wait
d.	
4.	The DMX Emergency Bypass Controller shall support a single bypass input using two input modes:
a.	Bypass triggering shall be supported via a maintained contact input configurable for normally open (N.O.) or normally closed (N.C.) operation
b.	The contact input shall support +12VDC wet input to provide interface with fire alarm or secondary trigging systems. Bypass controllers that do not support a fire alarm input shall not be acceptable.
C.	Mechanical
1.	The DMX Emergency Bypass Controller (DEBC) enclosure shall be a surface mounted enclosure with a removable cover, constructed of 16-gauge, formed steel with a removable front cover
a.	All components shall be properly treated and finished in fine textured, scratch-resistant, powder coat paint
b.	DEBC enclosure shall have a minimum of four keyed mounting holes for wall attachment
c.	DEBC enclosure shall have a visible label stating the product name, manufacturer name, indicator functions, control functions, ratings and listings
2.	The DMX Emergency Bypass Controller (DEBC) enclosure shall provide discrete high and low voltage wiring compartments with voltage barrier
3.	The DMX Emergency Bypass Controller (DEBC) shall have a single bi-color LED indicator visible from the exterior of the enclosure
a.	LED shall indicate Normal state with a “green” color light
1)	Normal state illuminates steady green when Power and DMX are present
2)	LED Off indicates Power or DMX are not present
b.	LED shall indicate Bypass state with a “red” color light
1)	Bypass state includes bypass input contact trigger or ‘test’ active
4.	The DMX Emergency Bypass Controller (DEBC) shall have a single test button accessible from the front of the enclosure without removing any panels
a.	The test button shall immediately trigger bypass state for as long as it is held down, and release the bypass state immediately upon release of the button
1)	The test button shall be momentary only
2)	The test button shall be recessed to prevent accidental triggering
5.	The DMX Emergency Bypass Controller (DEBC) shall have a single, internally accessible button for DMX Record (snapshot) with an indicator LED for record action
1)	The record button shall be momentary only and held for at least 3 seconds before activation to prevent accidental recording
2)	The LED indicator will flash rapidly when record function is active
3)	The LED indicator will illuminate steady when record function is complete
6.	The DMX Emergency Bypass Controller (DEBC) dimensions and weights shall not exceed:
a.	9” H x 11” W x 2” D, 
b.	8lbs (single output); 14.5lbs (multi-output)
D.	Electrical
1.	The DMX Emergency Bypass Controller shall be completely internally pre-wired by the manufacturer 
2.	The contractor shall provide input feed and control wiring to the provided terminals
a.	DMX Emergency Bypass Controllers (DEBC) shall support 100 to 277 volt input power, 50/60 Hz, 150mA maximum current
3.	DEBC shall support labeled terminations for two 24 – 10 AWG solid or stranded power wires
4.	DEBC shall support one Grounding Lug for 24-14 AWG solid or stranded ground wire
5.	DEBC shall support labeled, socketed termination connections for DMX Input and DMX Output wiring
a.	Terminations shall support Belden 9729 cable or equivalent
1)	DMX Termination kits for Belden 9729 shall be supplied with the controller
2)	Optional Termination kits for Belden 1583A (or equivalent Category 5 cable) shall be available from the manufacturer
6.	DEBC shall support labeled, socketed termination for the bypass contact input
a.	Termination shall support two, 30-12 AWG low-voltage wires
b.	The bypass input shall support a maintained normally open (N.O.) or normally closed (N.C.) dry contact input
c.	A +12VDC wet contact input shall also be available for interface to fire alarm systems.
d.	DEBC shall support socketed DMX transceiver chips	
1)	A spare DMX transceiver chip shall be supplied in a labeled, inactive socket
7.	The DMX Emergency Bypass Controller (DEBC) shall internally switch from the normal DMX input (pass through) to the bypass DMX output using electromechanical relays when triggered
a.	The DEBC shall have non-volatile memory for storage of a single recorded sequence of 512 channels
1)	The recorded sequence shall persist through power outages
2)	The default sequence shall have all 512 channels at “full” if no sequence is recorded
b.	The DEBC shall have a DMX baud rate of “Slow” (20 packets per second) for increased compatibility during bypass DMX output
8.	The DEBC shall be available in two versions capable of output to a single DMX line or up to six optically-isolated DMX lines 
9.	The DMX Emergency Bypass Controller shall be UL and cUL Section 924 LISTED for interaction with similarly listed products
