Section 16500 – EMERGENCY DMX BYPASS SWITCH

1.01  Emergency DMX bypass Switch

A.  GENERAL

Philips Strand Lighting’s Emergency DMX Bypass Switch provides Emergency and Panic Lighting control solutions for DMX driven House Lights and DMX controlled Lighting used in emergency and egress lighting. Each Bypass unit can handle Up to four (4) individual universes of DMX and can also act as a DMX splitter handling 1 in 4 out or 2 in 2 out routing scenarios. Bypass handles more than just emergency and has a separate trigger for Panic lighting states.

Each state - Panic or Emergency - can be set to trigger “snap shot” loads or can be set to drive all loads on each DMX path to 100%. Each state (Panic or Emergency) can be triggered via normally open, normally closed dry contacts, or from a 12VDC signal. Once the State is returned to Normal Bypass will also return loads to the DMX switch based upon the configured time. Return states can be timed at 1 second, 10 seconds, 1 minute, 10 minutes, or can be set to return under INTELLIGENT timing. INTELLIGENT timing will truncate the return to normal time when Valid DMX inputs are sensed.

B.  FUNCTIONAL

  1. The DMX Emergency Bypass Switch shall be capable of overriding a up to four (4) universes of ANSI E1.11–2008, USITT DMX512-A control signals from “Normal” to “EMERGENCY” or “PANIC” when a trigger signal is detected via a dry contact (normally open or normally closed) or a 12VDC signal user configurable trigger input. Any DMX bypass switch not capable of up to four universes of DMX control shall not be accepted.
  1. Emergency and Panic states can either be a “snap shot” of the incoming DMX signal or output all 512 outputs of each DMX universe to full intensity.
  1. If both Emergency and Panic states are triggered Emergency state will always take precedence over previous states.
  1. The DMX Emergency Bypass Switch shall be capable of three different operating modes:
  2. Normal: Up to 4 separate DMX universes can be routed through the Interface. The Interface routes the signals from DMX IN directly through DMX OUT connectors. The signals are routed through DPDT Relays (Common to Normally Closed contacts). The Interface does not alter the DMX IN to DMX OUT in any way (direct connect). The interface can also

be configured to support 4 separate DMX circuits, or configured to act as a Splitter. As a dual 1: 2 splitter, the Interface can route DMX IN A to DMX OUT A and B, and DMX IN C to DMX OUT C and D. As a single 1:4 splitter, the interface can route a single DMX IN A to DMX OUT A, B, C, and D.

b.  Emergency: When an Emergency signal is detected on the Interface's isolated Emergency Input port, EDBS will activate the DMX coupling relays and disconnect the DMX IN from the DMX OUT ports. EDBS will then output the saved Emergency DMX patterns to the connected lighting fixtures. It will continue to transmit the DMX patterns until the Emergency Input is removed and after a configured time delay. After the time delay, the Relays are once again relaxed and the system returns to the Normal Mode.

c.  Panic: Functions the same as the Emergency mode except that it can be programmed to transmit a different pattern if desired. Panic uses a separate Panic Input, separate Panic Learn and Test pushbuttons, and separate configuration DIP Switches.

  1. Each EDBS shall be capable of handling and splitting up to four universes of DMX – systems not capable of more than one universe shall not be accepted.

EDBS’s splitter mode can be configured to support 4 separate DMX circuits, or configured to act as a Splitter. As a dual 1: 2 splitter, the Interface can route DMX IN A to DMX OUT A and B, and DMX IN C to DMX OUT C and D. As a single 1:4

splitter, the interface can route a single DMX IN A to DMX OUT A, B, C, and D.

  1. The EDBS shall monitor the input trigger, after triggered state is released a Return to Normal state shall be accomplished via: Return states can be timed at:
  2. 1 second
  3. 10 seconds
  4. 1 minute
  5. 10 minutes
  1. INTELLIGENT TIMING Return to Normal state: INTELLIGENT timing will truncate the return to normal time when valid DMX inputs are sensed.
