echoflex Emergency Bypass Load Controller EREB Installation Guide

echoflex Emergency Bypass Load Controller EREB

Overview

The Emergency Bypass Load Controller (EREB) is powered by an emergency source to provide power to emergency lighting loads. The EREB ensures the emergency lighting is on during loss of circuit power, and also tracks the state of controlled lighting loads during normal operation. The EREB ensures a “lights on” override by using a normally closed emergency contact closure that interfaces with fire alarm and emergency systems.
The EREB is available in two models to provide installation options: Power Pack EREB-AP and DIN rail EREB-AD.

This document covers installation of all the EREB models. The product package includes the controller and lock nut for the EREB-AP model.

Model EREB-AP

Ensure that the junction box is clean and free of obstructions and that all wiring is installed correctly. The EREB-AP mounts directly to the exterior of the junction box or panel, either at the electrical lighting load or before the loads in the circuit. See Examples of Use on page 10.

Two sets of wire bundles are provided on the top of the device. One set is for emergency power input and the other set is for sensing normal power. In addition, a single loop jumper is provided to connect a remote triggering device, for example, a fire alarm (normally closed, dry contact closure). See Wiring Diagram on page 4.

1. Locate the normal and emergency circuit breaker panels and terminate power to the circuits.

2. Remove the cover plate and other hardware from the junction box to access the wiring.

3. Mount the controller with the 1/2” threaded nipple. Use wire nuts on all connections and individually cap any bare wires.

4. Connect the emergency power wiring leads.

   • Connect the Emergency Power In and Power Out wiring leads on the EREB-AP with the emergency lighting loads [Black 4 mm2 (12 AWG) and Red 4 mm2 (12 AWG)].
   •  Connect the Emergency Neutral [Gray 1 mm2 (18 AWG)] for the emergency circuit to the Emergency Neutral lead.

5. Connect the normal sense wiring leads.

   • Connect the Normal Power Sense [Black 1 mm2 (18 AWG)] and Normal Switch Sense [Red 1 mm2 (18 AWG)] wiring leads to the normal lighting circuit .
     Note : To ensure that the emergency lighting in the controlled area turns On in the event of a power loss, you must connect the Normal Power Sense wires upstream of any switched control device for the normal lighting loads.

   • Connect the Normal Neutral [White 1 mm2 (18 AWG)] lead to the normal Neutral for the lighting loads.

6. Are you are installing a remote triggering device to remotely activate the emergency circuit?

   • No: Go to Initial Test on page 8 to confirm the connection.
   • Yes: See Remote Activation Input below for wiring instructions.

7. Replace the cover plate and restore power to the circuits.

Wiring Diagram

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.

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.

   • Connect the Emergency Power In and Emergency Power Out wires to the screw terminals on the device in series with the emergency lighting.
   • Connect the Neutral for the emergency circuit to the Emergency Neutral screw terminal.

3. Connect the EREB-AD to the normal lighting and control device for the area controlled.

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.

6. Are you are installing a remote triggering device to remotely activate the emergency circuit?

   • No: Go to Initial Test on page 8 to confirm the connection.
   • Yes: See Remote Activation Input on the facing page for wiring instructions.

Wiring Diagram

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.

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.

Examples of Use

Switch Control Arrangement

• When normal power is present, the switch controls both the normal and emergency light fixtures.
• When the normal power is lost, the emergency light fixture turns ON regardless of the switch state.

Backup Arrangement

• When normal power is present, the emergency fixture is turned OFF.
• When the normal power is lost, the emergency fixture turns ON.
• Cap end with a wire nut or other suitable method to prevent contact with bare wire.

Phase Dimmer Control

• When normal power is present, the emergency fixture behaves as a normally controlled fixture.
• When the normal power is lost, the emergency fixture turns ON full.

0–10 V Fixture Control (EREB-AD model only)

• When normal power is present and the switch is closed, both 0–10 V controlled fixtures dim.
• When normal power is present and the switch is open, both 0–10 V controlled fixtures turn OFF.
• When the normal power is lost or fire alarm connection is broken, all fixtures turn ON full: the 0–10 V connection is opened and emergency fixture turns ON full.
