ECS-204
20A Power Conditioner & Sequencer
Introduction
Thank you for purchasing the Atlas Sound ECS-204 AC Power Sequencer and Conditioner. The ECS-204 has been designed to meet
most installation requirements for AC power distribution and equipment power protection. The 20A compact 1 RU unit features four
internal sequential timing sections, three on the unit and one to trigger an external device. All can be activated via the unit locally or
remotely. Front panel activation is via a momentary switch, while rear activation can be accomplished via a remote momentary switch,
latching switch, or by 5-24VDC. AC Mains Voltage can be monitored via the front panel from the precision Digital Volt Meter. The ECS-
204 has incorporated dual front panel USB charge ports that can be used to charge devices such as cell phones or music players. To
light the rack this charge port also supports an optional USB gooseneck lamp. The rear of the rack can be illuminated by the optional
Atlas Power 16" gooseneck LED lamp (AP-GNL) connected via an XLR style socket.
If a 20A AC Mains power source is not enough to meet the amperage demand of your system, the ECS-204 provides a sequenced
12VDC or contact closure output (Seq 4) that can be used to trigger other devices such as the Atlas Sound ECM-20SH 20A standalone
AC power module. Also, up to 3 ECS-204 can be linked together to give you 12 sequenced outputs. Sequence timing selection is made
by a rear panel switch selection. There are four choices that range from 3 seconds to 2 minutes.
The ECS-204 incorporates an Emergency Power Down (EPD) feature. The EPD may be required by the local fire code to pass site
inspection. This port when activated turns Off all channels at once. Unstable AC Mains voltage is one of the main reasons for
equipment failure. AC Spikes, or Transients, are commonly caused by lightning storms or utility power plant grid switchovers. The
amount of energy that can be injected into the power system can be immense with voltages reaching 6kV or amperage peaks of
3000A. These spikes are very fast and usually only last for a very short period of time. To protect against this potential problem, the
ECS-204 features Dual Clamping Suppression technology (DCS). If a spike intrudes the AC system, the ECS-204 incoming AC Mains
has special suppression circuitry to eliminate the unwanted energy and in the unlikely event of any energy getting passed the first
stage, each sequenced output section has redundant DCS circuitry clamping the unwanted energy. This circuitry is very fast and can
suppress unwanted energy within a nanosecond, while sustaining the suppression up to 2 milliseconds, thus ensuring virtually trouble
free protection.
The ECS-204 also features noise filtering for unwanted Radio Frequency Interference (RFI) that is commonly introduced into the AC
lines by nearby radio transmitters or wireless products. EMI filters are incorporated to reduce noise from Electromagnetic Interference
(EMI) from items such as electric motors, switching power supplies and lightning. The benefit of these filters can be seen on video
products or audibly by reduced static pops and external signal interference.
High and low AC Main line voltages are another major contributor to equipment failures. High line is also known as surges. Surges
usually are a slower steady state rise in voltages ranging from 128VAC and up. They can be caused by fluctuations in the utility
company’s power lines or industrial equipment turning On and Off and is on the same power leg of the building’s incoming AC. Low
line is also known as brownouts. This happens when the AC Mains drops below 107VAC. Most of the time it is caused by the utility
company not being able to supply enough power during heavy utility consumption time periods, such as heat waves. Another factor
would be from voltage drops in AC lines due to long transmissions. The ECS-204 will not only inform you if one of these conditions
occurs, but under extreme variances in the AC Mains, it will shut the power to the equipment Off. The Abnormal Voltage indicator on
the front panel will flash if the AC Mains is between 128VAC and 132VCA or 107VAC and 101VAC. This is to inform you that a surge
occurred and may have damaged voltage sensitive equipment. If an extreme voltage swing occurs above 132VAC or below 101VAC,
the ECS-204 Extreme Voltage Shutdown (EVS) protection circuit will automatically activate and turn all outlets Off until it is manually
reset or the voltage is stable.
The ECS-204 offers sequenced power management control, along with noise filtering and spike/surge protection making it the most
compact, effective power management protection system on the market today.

allow the turning of equipment On and Off in a particular order, to eliminate an in rush of current and audible pops that often occur
with non-sequenced power strips. It also can be used solely for protection against lightning strikes or voltage surges. If fuzzy video
or frequent static pops occur, the AC power conditioning will eliminate or reduce those inconveniences. The following are just a few
examples of applications the ECS-204 can be used:
• Restaurants
• Houses of Worship
• Schools
• Home Theaters
• Office Buildings
• Sports Bars

5. Sequence Indicator – There are four green LED active sequence outlet indicators labeled “SEQ 1”, “SEQ 2”, “SEQ 3”and
“SEQ 4”. Their sequence timing depends on the customer set settings, see the Sequence Settings Rear Panel section. When the
LED is illuminated, the corresponding AC outlet section on the rear of the chassis will be active or “Live”. Turned “On”, the order
of the trigger sequence is SEQ 1, SEQ 2, SEQ 3, SEQ 4. Turned “Off”, the order is SEQ4, SEQ 3, SEQ 2, SEQ 1.
6. AC Mains Wiring Polarity Fault Indicator – The Red LED will illuminate if the AC Mains Power Cord is plugged into an AC Mains
outlet that is wired incorrectly, such as when the AC Hot and the AC Neutral are wired backwards.
7. AC Mains Breaker Indicator – This Red LED will illuminate if the maximum unit current draw is exceeded. The breaker rating is
15A, but will handle higher peaks for a short period of time. The LED will illuminate until the AC Mains Breaker is reset.
8. AC Fault Indicator – Although the Dual Clamping Suppression (DCS) circuit virtually assures protection from most transient voltage
spikes and surges, nature has a way of occasionally creating electrical forces that are beyond the capabilities of any device to
absorb without some degree of damage. In the rare instance that this occurs and the DCS circuit has been damaged, the Red
“AC Fault” LED indicator will illuminate and an internal buzzer will sound. The ECS-204 will also shut off permanently until the unit
is repaired. Note: If the AC Fault LED is illuminating it is important to have all equipment that was connected to that AC Mains Line
inspected for proper operation.
9. AC Mains Abnormal Voltage Indicator – This LED flashes under several AC Mains fault situations that are listed below. Normal
operating voltages for AC Mains voltage is considered to be between 108VAC and 125VAC. Any voltages exceeding those
parameters are considered a risk to damage equipment plugged into the ECS-204.
10. AC Mains Voltage Indicator Meter – When the ECS-204 is plugged into an AC mains source, the precision voltage meter will
Indicate the reading within 2%. The unit does not have to be Sequenced On for the unit to display the AC Mains volt reading.
Below are reading conditions and fault codes.
• High AC Line Mains – The Abnormal Voltage LED will flash between 128VAC and 132VAC indicating possible damage may
occur to equipment due to high AC Mains voltage. The ECS-204 outlets will remain active but the LED will stay flashing even if
the voltage returns to a normal operating range. To stop the LED from flashing the system activation switch must be cycled
“Off”. Note: It is recommended prior to proceeding to have the AC Mains inspected by an electrician.
• Low AC Line Mains – The Abnormal Voltage LED will flash between 101VAC and 107VAC indicating possible damage may
occur to equipment due to low AC Mains voltage. The ECS-204 outlets will remain active but the LED will stay flashing even if
the voltage returns to a normal operating range. To stop the LED from flashing the System Activation Switch must be cycled
“Off”. Note: It is recommended prior to proceeding to have the AC Mains inspected by an electrician.
• Extreme High AC Line Mains – If the AC Mains reach 132VAC, the EVS (Extreme Voltage Shutdown) circuit will be triggered
to shut off the AC outlets while activating the Abnormal Voltage LED. The Red LED will illuminate steady and the AC Mains
Voltage Meter will flash HI (High Voltage) during this mode. The ECS-204 EVS circuit can be set to either Auto Reset or Manual
Reset mode. Read below how to select and set the proper reset mode for your installation. Note: If the EVS is activated, it is
recommended prior to proceeding to have the AC Mains inspected by an electrician.

Installation
Before installing we strongly suggest you read the entire manual to ensure you benefit from all the features of the ECS-204. The
ECS-204 can be placed on a shelf or rack mounted in a standard 19" width rack. Placement within a rack is not critical but the rack
should be within 6' of dedicated 20A AC outlet. Always make sure the 20A outlet is properly inspected by a certified electrician prior to
connecting the ECS-204. Below are a few installation tips.
• After plugging the ECS-204 into a 20A AC Mains outlet inspect the Wiring Fault LED for illumination. The LED should not be on.
• Inspect the equipment that is to be plugged into the ECS-204 to ensure it does not exceed 15A total amperage draw.
• Divide the equipment into three categories. Pick the outlets that match the outlets equipment use.

AC Power Cord Retainer System
Your Atlas Power product comes with an AC Mains Power Cord Retainer System. This system prevents the power cord
from being removed without the use of a screwdriver. Follow these steps for installation.
Note: Installation of this product must be done by a certified electrician for a permanently connected apparatus provided
neither with an all-pole mains switch nor an all-pole circuit breaker. A readily accessible disconnect device shall be
incorporated in the building installation power wiring. The installation shall be carried out in accordance with all applicable
installation rules in accordance with all applicable federal, state, and local laws, regulations, safety codes and ordinances.
1. Locate the 6⁄32 screw, retainer clip, and zip tie.
2. Locate the AC wall outlet that will be used to power the
Atlas Power product. Remove the center screw securing the
cover plate to the AC outlet.
4. Wrap the zip tie around the power cord as shown in Figure 4.

Troubleshooting
Note: ALL TROUBLESHOOTING SHOULD BE DONE BY A CERTIFIED ELECTRICIAN
Issue 1 - Wiring Fault LED is illuminated.
Possible Cause - AC Mains outlet is wired incorrectly.
Action Needed - Contact a certified electrician to inspect the building’s wiring.
Issue 2 - No power to the AC outlets.
Possible Cause - Circuit breaker has tripped due to excessive load.
Action Needed - Remove one piece of equipment from the ECS-204, and push the breaker re-set tab located on the front panel.
Note: We suggest first locating the highest power-consumer such as a power amplifier and disconnecting or turning down that
unit. If the ECS-204 breaker continues to trip, relocating some of the gear may be required.
Issue 3 - No power to the AC outlets, “Abnormal Voltage” indicator is illuminated, the Volt Meter is Flashing and you hear a buzzer
from the unit.
Possible Cause - The AC Mains Voltage exceeded 132VAC or the voltage dropped below 101VAC.
Action Needed - Measure the AC mains before the ECS-204. If the voltage is between 117VAC and 123VAC you may proceed to
reset the ECS-204 by restarting the sequence. Note: It is important to have all equipment that was connected to that AC
Mains Line inspected for proper operation. If the problem persists, contact your local power company for the cause of unstable
AC line conditions.
Issue 4 - Abnormal LED Flashing when you have power to all outlets.
Possible Cause - The AC Mains Voltage exceeded 128VAC or the voltage dropped below 107VAC.
Action Needed - The ECS-204 must be re-sequenced to turn off the LED. Measure the AC mains before the ECS-204. If the
voltage is between 117VAC and 123VAC you may proceed to reset the ECS-204 by restarting the sequence. Note: It is
important to have all equipment that was connected to that AC Mains Line inspected for proper operation. If the problem persists,
contact your local power company for the cause of unstable AC line conditions.
Issue 5 - AC Fault LED is Flashing, a buzzer is sounding and you have no power at any outlets.
Possible Cause - Although the Dual Clamping Suppression (DCS) circuit virtually assures protection from most transient voltage
spikes and surges, nature has a way of occasionally creating electrical forces that are beyond the capabilities of any device to
absorb without some degree of damage. In the rare instance that this occurs, the DCS circuit has been damaged during the
suppression.
Action Needed - If this happens, the ECS-204 will shut off and the unit will need to be repaired or replaced. It is important to
have all equipment that was connected to that AC Mains Line inspected for proper operation.
