Echoflex Installation Guide
Emergency Bypass Load Controller
The remote device that triggers the Emergency circuit ON must provide a
normally closed, maintained dry contact closure for fire alarms. When the
remote device is activated, the contact closure opens and the contacts
force the EREB-AP into the emergency ON state.
Note: When using 1 mm2(18 AWG) wire, the remote triggering
device, test switch, or emergency system must be installed within
305 m (1,000 ft) of the EREB.
1. Cut the blue wire loop in the middle of the wire lead. Doing this
provides two leads, which are the connection points for both the
contact input and contact output to a remote triggering device.
2. Connect the two leads to the normally closed single pole contacts on
the remote device or test switch.
3. Go to Remote Activation Test on page 9 to confirm the connection.
Model EREB-AD
The EREB-AD is designed to attach to lighting control panels or electrical
enclosures that are fitted with a DIN rail.
Six screw terminals on the bottom of the device are used to connect
normal sense and emergency power wires. Four screw terminals on the
top of the device are used for the following connections:
•
The two terminals on the left have a factory-installed wire loop
(jumper). It provides a connection to a remote triggering device
(normally closed, dry contact closure, such as a fire alarm). When the
normally closed contact is triggered, the contact input opens,
activating the emergency lighting.
•
The two terminals on the right provide termination of 0–10 V, LED
driver loads, or fluorescent lighting control.
1. Snap the device onto an installed DIN rail in the upright position at
least 5 cm (2 in) away from any heat-generating devices. Tension clips
on the device provide an audible click when the device is installed
properly.

Remote Activation Input
The EREB-AD offers a normally closed, dry contact input to accommodate
connection to a fire alarm panel, security system, or test switch. This
input ships from the factory with a blue wire loop (jumper) connected to
two of the top screw terminals. It is a complete loop that disables remote
activation. Do not remove this jumper unless you are installing a remote
triggering device.
Note: Echoflex recommends that you power up and test your
system before connecting to a remote device. Do not remove the
jumper unless you are installing a remote triggering device.
The remote device that triggers the Emergency circuit ON must provide a
normally closed, maintained dry contact closure for fire alarms. When the
remote device is activated, the contact closure opens and the contacts
force the EREB-AD into the emergency ON state.
1. Power up and test your system before installing a remote activation
input to your EREB. See Initial Test on page 8.
2. Remove the wire loop jumper from the Remote Loop In and Remote
Loop Out terminals.
3. Connect the Remote Loop In and Remote Loop Out terminals on the
EREB-AD to the single pole contacts on the remote device or test
switch.
4. Go to Remote Activation Test on page 9 to confirm the connection.
Configure a Time Delay
If your lighting requires a warmup period (for example, for high-intensity
discharge [HID] lamps), you can configure a time delay to keep the
emergency lighting on for a period of time after the normal power is
restored. The default time delay is zero. To configure a longer transition
time follow the steps below.
1. Press the [Option] button on the EREB. Both the Status and
Remote LEDs will blink to indicate the current time delay
configured.
2. Press and release the [Option]
button to cycle through the
settings, and stop when the
blink pattern matches the
setting you want.
3. Wait 10 seconds for the EREB
to save the setting and resume
normal operation.
No. of Blinks Time Delay
1 blink no delay (default)
2 blinks 10 seconds
3 blinks 30 seconds
4 blinks 10 minutes
5 blinks 15 minutes

Initial Test
Initial testing of the EREB should be done with the Remote Loop In and
Remote Loop Out jumper installed on the EREB-AD and the blue loop
uncut on the EREB-AP.
1. Turn On the circuit breaker in the emergency panel for the controlled
circuit. The Status LED on the EREB shows red. With only the
emergency circuit On (normal power should be Off), the emergency
lighting should be activated.
2. Temporarily disconnect and cap the wire lead connected to the
Normal Switch Sense terminal on the EREB. This disables the normal
control function and allows exclusive testing of the emergency On
functionality.
3. Turn On the circuit breaker in the normal panel for the controlled
circuit. The Status LED on the EREB shows green, indicating that
normal power is present and emergency lighting is not required.
4. Confirm the automatic emergency On functionality by turning Off the
circuit breaker in the normal panel. The connected emergency
lighting should immediately turn On again and the Status LED on the
EREB shows red.
5. With the normal circuit breaker secured Off, reconnect the Normal
Switch Sense wire to the terminal.
6. Turn On the normal circuit breaker. The EREB should now behave as
described in Examples of Use on page10.
Note: If you are installing a remote activation input to the EREB,
see Remote Activation Input on page4 for the EREB-AP or Remote
Activation Input on the previous page for the EREB-AD.
Manual Switch Test
The EREB features a button to manually switch the load from normal to
emergency power for test purposes.
1. Press and hold the red [Test] button on the front of the device.
2. Verify the emergency relay closes. This is apparent when the
emergency loads turn on according to your installation.
3. Release the button to return to normal operation.

What does the Test button do?
•
EREB-AP: [Test] button simulates the loss of normal power and
bypasses the normal switching of power to the fixture. When using
the EREB-AP with a directly-controlled emergency fixture containing
a control input (for example, 0–10 V or DMX), note that the [Test]
button only bypasses the normal method of switching power to the
fixture. Pressing the button has no effect on the control device
providing data input to the fixture. To test this type of system, you
must enter the test mode of the control device (usually by turning
off normal power to the entire system).
•
EREB-AD: [Test] button simulates the loss of normal power and
bypasses the normal control of supply to the fixture. It also
interrupts the 0–10 V or DMX control circuit, thereby illuminating
the load and bypassing the normal control signal to the load. In a
properly operating system, the load should illuminate upon pressing
the [Test] button.
Remote Activation Test
1. Do one of the following according to the EREB model:
•
EREB-AD: Connect the Remote Loop In and Remote Loop Out
terminals on the EREB-AD to the single pole contacts on the remote
device or test switch. See Remote Activation Input on page7.
•
EREB-AP: Cut the Remove Loop wire and connect the remote
activation trigger device or test switch. See Remote Activation
Input on page4.
With the remote device in normal mode (contacts closed), the Status LED
on the EREB will show green and the device operates as it did with the
factory-installed jumper.
When the remote device activates, the Status LED shows red, indicating a
switch to emergency state. The EREB activates emergency On mode and
the Remote LED shows amber, indicating remote device control.
