A21 Lighting Control Panel
OVERVIEW
1. About A21 Lighting Control Panels
Strand Lighting A21 Lighting Control Panels are high-performance, wall mounted lighting control panels which offer
a wide range of dimming and relay modules to accommodate any lighting control application. All A21 Lighting
Control Panels accept any combination or mixture of LED, incandescent, and fluorescent dimming or non-dim
modules to fit any project needs.
A21 Lighting Control Panel IGBT Dimming Modules contain an on-board, intelligent microprocessor that adjusts
and maintains proper voltage and current in response to changes detected in the load and electrical service, which
serves to extend lamp life. The microprocessor also automatically suppresses surges, and protects against short
circuits. IGBT dimmers significantly reduce neutral harmonics and when configured to operate in Low Harm® mode.

reference only in the event a Backplane PCB requires re-configuration or changing in the future.
A21 Dimmer Modules are connected to a Backplane PCB(s), which is pre-installed in the panel. Each Backplane
PCB accommodates up to three module connections. Depending on your dimming system, there may be up to 16,
three-module Backplane PCBs connected together, and cannot contain more than 96 dimmers (Dual Dimmer Module
= 2 dimmers; Quad Dimmer Module = 4 dimmers) total when panels are used in a Master/Slave configuration. Before
any dimmer modules are installed, it will be necessary to address the Backplane PCB(s).
• Each Backplane has a rotary switch that is used to set the Backplane's address (0-15).
• Each Backplane has a set of jumpers that allow it to be configured as a Dual or a Quad Backplane. Set to Dual only
if all dimmer modules to be connected to the backplane are Dual dimmers.
• Each Backplane also has a termination header. The termination is set to Term only on the first and last Backplane
(all others are set to Thru).
The first Backplane is the top Backplane in the cabinet that contains the A21 Rack Control Module (RCM). The
Backplanes will be addressed from top to bottom in the first cabinet. If another slave cabinet (no RCM) is to be
added, continue the addressing from top to bottom as well. Continue this method of addressing until the last
Backplane in the last cabinet is connected. Slave cabinets are connected to the first cabinet and to additional slave
cabinets using an 8-conductor (CAT5e UTP) cable, no longer than 1000 feet system wide.

To address/configure Backplanes:
First Backplane:
Step 1. Set rotary switch of first Backplane to 0. (Refer to Figure 10.)
Step 2. Set Backplane configuration jumper to either Dual or Quad.
Step 3. Set Termination jumpers to Term.
Next Backplane:
Step 1. a) If previous Backplane is set to Dual, then set rotary switch on
this Backplane to the previous Backplane's setting plus 1.
Example: If previous setting was 0, then set this switch to 1.
Quad/Dual
Jumper
b) If previous Backplane is set to Quad, then set rotary switch on
this Backplane to previous Backplane's setting plus 2. Example: If
previous setting was 0, then set this switch to 2.
Step 2. Set Backplane configuration jumper to either Dual or Quad.
Step 3. If this is not the last Backplane to be configured, then set
Termination jumpers to Thru. If this is the last Backplane to be
configured, then set the Termination jumpers to Term.

A21 Lighting Control Panel
EMERGENCY LIGHTING OPERATION (UL924)
1. Overview
When required, the A21 Lighting Control Panel may be used to energize emergency lighting circuits in the event of a
loss of power. A21 Panels may be custom configured at the factory with special software and hardware to allow the
unit to comply with UL924 Electronic Bypass. When configured in this mode, the A21 Panel allows select circuits to
be energized at 100% output upon activation by a control signal. Circuits not identified as emergency may be locked
"Off" or can "Ignore" the emergency state and still respond to local controls.
When A21 Panels are used as part of an emergency lighting control system, feed power supplied to the A21 Panel
must be switched by an upstream UL1008 Listed Transfer Device.
To trigger the A21 Panel to enter the emergency mode, a control signal (Contact-Closure, open) must be provided to
the panel, and connected to the Panic #1 input, located on the Control PCB. Strand Lighting recommends the use of a
3-phase UL924 or UL 1008 compliant phase loss relay interface to monitor normal power and provide a control
signal to the A21 Panel in the event of a disruption of any phase of the normal power feed.
When the A21 Panel is in an active emergency mode, the LCD display will read EMERGENCY MODE ACTIVE
and the display backlight will flash.
Note: UL924 operation applies only to A21 Panels which have been configured at the factory for Emergency
Lighting Operation. If a previously installed A21 Panel is required to operate emergency lighting and needs to be
updated in the field, please contact Strand Lighting Technical Support at 1-214-647-7880.
2. Configuring Emergency Operation
Strand Lighting's Dimmer.net software provides the only interface for for configuring A21 Lighting Control System
UL924 options. Refer to the Dimmer.net manual for full UL924 explanation. Dimmer.net software and manuals may
be downloaded at www.strandlighting.com.

NOTICE TO CONTRACTOR
Technical Services Checkout Procedure
DO NOT APPLY POWER TO THE LIGHTING CONTROL SYSTEM!
No part of this system may be energized or operated until the installation has been approved by a Strand Lighting
Technical Services Representative. Violation of this Requirement may damage components and therefore constitute
misuse under standard warranty terms. Such misuse may relieve Strand Lighting of any and all further obligations
under the terms of this warranty.
Equipment MUST be installed per the Strand Lighting drawings.
All installation and wire terminations MUST be completed per the Strand Lighting drawings prior to the arrival of the
Technical Services Representative:
1) Input power must be connected to the system, but not energized.
2) All loads must be connected and all lighting instruments must be lamped.
3) All control wiring must be installed and terminated - including DMX512, Ethernet and Vision.net.
4) All equipment, including controllers, accessories, keys, cables and manuals must be in place.
5) Personnel for training (i.e. the users), as well as any other personnel required by contract and/or
specification must be available for training at the completion of the Checkout and Energization.
6) An owner (or authorized representative), as well as any other personnel required by contract and/or
specification will be present to accept the system.
The Technical Services Representative will only be able to:
• Ensure that the system is properly installed and functions correctly, including troubleshooting and providing guidance to the contractor to correct any problems.
• Train personnel in the operation of the Lighting Control System.
The Technical Services Representative will not be able to:
• Install equipment or make electrical connections required of the installing contractor, including DMX512, Ethernet, Vision.net, and/or any other connections that require a licensed electrician.
• Return to instruct any personnel who missed the original training session.
If the above requirements have not been met, the Technical Services Representative will be required to leave the job
site. Return trips to complete the Technical Services Checkout require a separate Purchase Order and will be invoiced
at the cost of travel (including per diem and travel time door-to-door), hourly labor, and a minimum daily on-site
charge. Rescheduling will require 3 weeks notice, subject to Technical Services Representative availability.
------------------------------------------------------------------------------------------------------------------------------------------Please feel free to contact Strand Lighting Technical Services (1-214-647-7880) should there be any questions
regarding the installation of the equipment or requirements regarding the Technical Services Checkout.
When all requirements have been met and the system is ready for inspection, please download and complete the Field
Service/Commissioning Request Form (PDF). This form can be found on the Main Support Page of the Strand
Lighting website: www.strandlighting.com
