Acuity Brands DMeXit Emergency Controller

Product Information

The DMeXit Emergency Controller is a device that provides emergency power to a system when the normal power source is unavailable. The controller has several status indicators, including PWR, DMX, and EM, which indicate the power source, active DMX source, and emergency mode status, respectively. The controller also has internal indicators, including Processor and Record Custom Snapshot LEDs. The device has several buttons, including Test, Record Custom Snapshot, and Default Snapshot.

Important Safeguards

1. All servicing should be performed by qualified service personnel.
2. When using electrical equipment, basic safety precautions should always be followed.
3. Always read complete installation instructions prior to installation.
4. DMX input/output ports must be connected to low-voltage data lines only. Do not connect DMX ports to high voltage sources.

DMeXit Emergency Controller

OVERVIEW

The Pathway DMeXit is a UL924 certified controller de-signed to send a control signal to DMX lighting in emer-gencies to satisfy minimum luminance levels for egress lighting. DMeXit may be triggered using a wet or dry contact closure from other building management sys-tems, or the integrated phase loss detection device. Upon trigger, a user-recordable snapshot of a single universe DMX will be transmitted to four separate data runs. The outputs are optically isolated to ensure max-imum reliability and are fully RDM compliant so that your entertainment console or architectural controller still has maximum flexibility when it comes to commis-sioning and monitoring your system during normal op-eration. There are multiple options for restoring normal operation after conditions have been cleared, including user programmable time delays, sensing of valid input signal from the normal controller or a remote restore button for facilities or stage managers.

IMPORTANT SAFEGUARDS

1. All servicing should be performed by qualified service personal.

2. When using electrical equipment, basic safety precautions should always be followed including the following:
   READ AND FOLLOW ALL SAFETY INSTRUCTIONS.

   • Do not use outdoors.
   • Do not mount near gas or electric heaters.
   • Equipment should be mounted in locations and at heights where it will not readily be subjected to tampering by unauthorized personnel.
   • The use of accessory equipment not recommend by the manufacturer may cause an unsafe condition. e. Do not use this equipment for other than its in-tended use.

3. The Emergency Circuits for this panel, must be fed from a UPS, generator, or other guaranteed source of power during emergency and power outage situations.

4. CAUTION – This equipment may be fed by more than one power supply source. To reduce the risk of electric shock, both normal and emergency sources feeding this unit should de-energized before servicing any equip-ment connected inside the marked high voltage com-partments.

5. Pathway assumes no responsibility for claims arising out of improper or careless installation or handling of this product. Failure to follow any of these instructions could void product warranty.
   Always read complete installation instructions prior to installation!

PLD WIRING DETAILS

Auxiliary Contacts from Fire Alarm Control Panels, Security Systems, or a remote test switch may trigger emergency mode if connected using the auxiliary contact closure input terminals on the LME 924. Dry contact relays or maintained switches may be used. Consult equipment manuals to verify auxiliary switches are dry contacts and maintained when active. When contact is made by the auxiliary equipment the LME 924 will trigger emergency mode and hold that mode until the contact(s) opens and the Restore time of how you have DIP switches 5,6, &7 set expires. For example if the LME 924 opens the contacts and your Restore Time is set to Factory Default of 10 seconds, it will take an additional 10 seconds before it returns to DMX pass-thru rather than emergency. There are (2) auxiliary contacts on the LME 924 which share equal priority. When EITHER auxiliary contact is closed emergency mode will be triggered. If your system is equiped with a PLD do not use parallel connections from an auxiliary source to the CCI connection on the electronics, wire them to the auxiliary connection on the LME 924.

Test Button

Press to activate emergency look, it will last for 30s. + Restore mode as determined by DIP switches 5,6,& 7. Press and hold for 3s to end test + Restore mode as determined by DIP switches 5,6,& 7.

In permanent installations, DMX512-A cables may be either one of two basic cable types: cables specified for use with EIA-485/EIA-485-A or EIA-422, and cables specified as EIA/TIA568 Category 5 or higher. Category cable meeting the requirements of a category higher than Category 5 is permissible. For DMeXit installations, we recommend Category cable and the supplied Insulation Displacement Contact (IDC) connectors.

ISO/IEC Category 5 Cables Use Insulation Displacement Contact Connectors

ISO/IEC Category 5 Cables Use Insulation Displacement Contact Connectors

Pathway Connectivity recommends you download and follow ANSI E1.27-2: Standard Wiring Practice for Permanently Installed Control Cables for Use with ANSI E1.11 DMX512-A available at https://tsp.esta.org/tsp/documents/published_docs.php.

Here are some additional notes abbreviated from the ANSI Standard.

• Shields and drain wires exposed by the process of preparing the cable for termination should be insulated from accidental contact with earth ground, data +, data – and data common.
• Under no circumstance should any cable conductor or shield be connected to earth ground
• Direct termination of a permanently installed cable on a male RJ-45 should not be allowed.

If using stranded twisted pair cables, you must use PWCON SPARE CSC3. See Pathway Accessories, Inserts and Spare Connectors table below for ordering information.

EIA-485 type cables (i.e., Belden, Proplex, etc) Use Compression Screw Connectors

XLR5 Pin| Wire| Function| Pathway CSC
Pin 1| Shield| Data Common| 1 (black)
Pin 2| Pair 1| Data – (complement)| 2 (green)
Pin 3| Pair 1| Data + (true)| 3 (red)
