1.0 J-PACK - DIMMER PACKS - GENERAL
1.1 On power up, J-PACK dimmers shall default to "Basic Mode" of operation permitting access to only two menus; DMX Address and DMX Termination. J-PACK's advanced features access shall require a specific button push sequence in order to protect all programmed system configuration/data from accidental or unauthorized access.
1.2 J-PACK dimmers shall be capable of dimming standard incandescent, quartz, SCR (silicon controlled rectifier) dimmable electronic fixtures, and SCR dimmable LED lamps and fixtures.
1.3 J-PACK dimmers shall be powered by a 120/208 VAC 3Ø or 120/240 VAC 1Ø supply of up to 30 and 40 Amps respectively per phase. Individual 13 Amp magnetic load breakers shall permit full rated operation in performance environments. Voltage range shall be selectable from the menu for either 120VAC or 230VAC operation.
1.4 J-PACK dimmer outputs shall employ an exclusive "lamp warming" technique that extends lamp life by limiting the in-rush current to cold lamp filaments by up to 70% over other performance dimmers.
1.5 An LCD user interface for ease of set up and monitoring. All programming shall be via a user-friendly, intuitive and self-prompting menu structure. No PC or special software will be required.
1.6 DMX512 start address shall be addressable in single channel (offset) or individually (patch) on a per circuit/dimmer basis. It shall be possible to address any dimmer to any channel within the entire DMX 512 universe or all dimmers to a single DMX channel.
1.7 Dedicated DMX IN and DMX THRU ports shall be supplied internally via 3 pin break-away connectors as well as externally via 5-PIN XLR connectors.
1.8 Two auxiliary contacts inputs shall be supplied internally as well as externally via 3-PIN XLR connector. Dry-contact input triggers shall activate stored DMX snapshots with time fade for automation with other AV control equipment. It shall be possible to program the inputs for "load shedding" applications when interfaced to photocell, aux. sensor or BMS for power management applications.
1.9 Each individual dimmer in the dimmer cabinet shall be capable of being assigned one of four dimmer curves: incandescent square law curve, direct curve, linear curve, or non-dim (50% threshold with a ±5% hysteresis).
1.10 Thermal protection shall be employed on both the internal heat sink as well as internally in the CPU. An active over-temp input shall illuminate a red warning LED when an internal temperature of 75°C is measured. An internal temperature of 80°C shall immediately disconnect all dimmer control outputs.
2.0 CONTROL PCB
2.1 J-PACK's shall employ the "system-on-a-chip" advanced "3000 Series" digital technology. The control electronics shall be contained on the Multiple Application Dimmer Driver (MADD-6) and its associated User Interface Board (UIB). Advanced state-of-the-art voltage regulation hardware and software will ensure >1% accuracy on all dimmer outputs.
2.2 The MADD-6 will operate with a voltage input range of 85-264VAC at 50 or 60Hz.
2.3 J-PACK's shall be capable of memorizing and storing up to six presets in the form of a DMX "snapshot" or individually programmed via the keypad. Scene playback shall be seamless on loss of DMX as well as allowing high resolution fades between scenes. Scene playback shall be optionally triggered from one or both of the contact inputs. Each scene shall have a selectable fade time from 0-99 seconds.
2.4 The DMX inputs shall comply with USITT DMX512-A (ANSI E1.11 - 2008), standard protocol for digital data control. DMX data shall take priority over an active auxiliary contact input.
2.5 Compliance with the International Energy Agency's "One Watt Initiative" stand-by power requirement. Please refer to U.S. Executive Order #13221. Processor standby power on J-PACK dimmer packs shall not exceed 1 Watt.
2.6 J-PACK's shall allow "back up" of all system configuration data. All data shall be protected from power failure by EEROM for a minimum of 100 years.
2.7 The face of the J-PACK shall include an LCD display and momentary, self-illuminating push buttons for function select, parameter setting and feature monitoring. All programming shall be via a user-friendly, intuitive and self-prompting menu structure. It shall not be necessary to use a PC or any external programming devise to configure or set up any function of the J-PACK.
2.8 J-PACK's shall support the following menu items:
Basic Menus (power up default access only)
1. ADDRESS Set the DMX start address.
2. DMX TRM Enable or disable termination on the DMX input.
Advanced Menus
3. SCENESET Enable and setup 6 different backup scenes.
4. FADETIME Set the fade time for each of the six scenes from 0 to 99 seconds.
5. SNAPSHOT Record DMX levels into the backup scenes.
6. DIM TEST Test the dimmer outputs one at a time or all at once.
7. MONITOR View the control level to each dimmer output.
8. SH TIME Set the DMX status hold time from 0 to 99 minutes or infinite.

2.9 J-PACK face panels shall include a green LED indicator for power supply and microprocessor status. The LED, when illuminated, shall indicate normal operation, and when flashing shall indicate a hardware fault. A power supply or power failure, shall cause the LED to extinguish.
2.10 J-PACK face panels shall include three green LED's for phase detect and one yellow LED for data receive indication. Loss of accurate phase detect signal and/or invalid DMX512 data shall cause the corresponding LED to extinguish.
2.11 J-PACK face panels shall include one red LED for active alarm status or dimmer pack over temperature. Active inputs shall cause these cause the corresponding LED to illuminate.
2.12 A reset push-button shall be included on the face panel of the J-PACK's. Resetting the unit, whether by the reset button or power up shall not affect any stored parameters or presets, and dimmer outputs shall automatically return to their former status.
2.13 All face panel buttons shall be blue LED back lit with adjustable intensity.
