Remote Activation Input

The EREB-AP 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) on the side of

the device. It is a complete loop that disables remote activation. Do not

cut 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.

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.

2. Terminate the EREB-AD to the emergency lighting for the area

controlled as shown in the Wiring Diagram on the next page.

a. Connect Emergency Power In and Emergency Power Out wires to

the screw terminals on the device in series with the emergency

4. Connect the normal lighting circuit to the Normal Power Sense,

Normal Switch Sense, and Normal Neutral screw terminals.

Note: To ensure that the emergency lighting connected to the

device turns On in the event of a power loss, the Normal Power

Sense wire must be connected upstream of any switched control

device for the normal lighting loads.

5. If you are connecting to 0–10 VDC or fluorescent lighting loads,

connect to the terminals, labeled 0–10 V/ FLO. See Examples of Use

on page 10 for more information.

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.
