ApplicationsBy using our Automatic Load Control Relays, you are able to complete your emergency lighting applications.

• High contact ratings allow for multiple loads on a single relay unit.

• Emergency lighting can be controlled under normal conditions using the switch input.

• Under normal operation, emergency light can be controlled by a controller using the dry contact input.

• The dry contact output can be used to override 0-10 V dimmers to full brightness (or for feedback to controllers, etc.)

• The on-board local test button and LEDs allow for installation to be tested immediately.

• A two second self-test of the unit is performed every time the wall switch input is turned off.

• Remote test capability allows for a button, switch, controller, fire alarm panel, etc. to be conveniently mounted anywhere desired. [Class 2 acceptable] See model ESRTB (remote test button). See page 14 for ESRTB.

• Different housings allow for wall or nipple mount (model ESRN), or ballast channel mount (model ESRB).

Input and Output Characteristics

Mechanical SpecificationsElectrical Specifications (ESRB, ESRN)

BLACK Normal Hot Can be different voltage than Emergency.

WHITE/BLACK Switch Input (Self-Test Input)

WHITE/BLACK wires must be from same

branch circuit as BLACK and RED. When

switched off, a two second delay keeps the

load on to test emergency power. This does

not test feedback/dimmer output.

RED Normal Neutral or other Phase Can be different voltage than Emergency.

Typical Applications



Test Procedure: Four Options to Test the ESRB and ESRN After Installation:

Initial Test for Correct WiringApply Emergency Power to the Emergency Power Input and Normal Power to the Normal Power Input. (If using the Wall Switch Input, apply Normal Power to the switch also, but keep the switch OFF/OPEN.) a. The Red LED (Emergency Power available) should be ON. b. The Green LED (Normal Power available) should be ON. c. The Yellow LED (Load Status) should be OFF. d. The Load should be OFF. e. The Feedback/Dimmer Contact should be CLOSED.

To test the ESRB and ESRN periodically, repeat the appropriate Test Procedure above in accordance with national and local codes.

Local Test Button1. Turn switched circuit OFF. Emergency light should be OFF.2. Press and hold “Local Test Button”3. Emergency light should turn ON.4. Release “Local Test Button” and emergency light should turn OFF.

Remote Test Button (Model ESRTB - sold separately)1. Turn switched circuit OFF. Emergency light should be OFF.2. Press and hold “Remote Test Button”3. Emergency light should turn ON.4. Release “Remote Test Button” and emergency light should turn OFF.

Wall Switch or Controller Contact1. Turn ON switch if not already on.2. Emergency light should turn ON.3. Turn wall switch OFF.4. Emergency light will remain on for two seconds before turning OFF.

Troubleshooting

Condition Action

Red LED is OFF Check Emergency Power Input wiring (BROWN and YELLOW wires) and voltage.

Green LED is OFF Check Normal Power Input wiring (BLACK and RED wires) and voltage.

Yellow LED is ON but Load is OFF

• Check Load wiring (BLUE wire and Load’s neutral). • Verify Load’s operating voltage is the same as the Emergency Power Input Voltage. • Check bulbs and ballast. • Replace unit.

Load is ON but Yellow LED is OFF

Replace unit.

Yellow LED and Load do not turn on when being tested

• Check bulbs and ballast. • Check wiring connections if using a remote test option. • Press local test button on the unit. • Replace unit.

Yellow LED and Load will not turn OFF

• Verify status of Normal Power Input. • Open Wall Switch Input. • Verify that no test inputs are stuck closed. (i.e. Remote Test Input is not closed).

When Normal Power is present, the ESR relay coil is activated and the emergency panel is fed from Normal Power. The lighting load can be switched on/off using the existing wall switch.

When Normal Power drops out, the ESR coil is deactivated and N/C contact falls closed. The Automatic Transfer Switch changes over to backup (generator) power, and the Emergency Light remains illuminated, regardless of the position of the existing wall switch, while the Normal Lighting is off.

Bypass/Shunt Relays & Dimming Override Application

Our Bypass/Shunt Relays are UL924 Listed and suitable for shunting around wall switches and/or lighting control panel circuits, in order to turn on emergency lighting when normal utility power is lost. In certain applications where a designated emergency light is desired for dimmed normal lighting, our UL924 relays will open the dimming control and override the switch position or 0-10 Vdc controller output to provide full illumination when normal utility power is lost.

Dimming Override Low Voltage Application

• When Normal Power is present, the ESR coil is activated and the N/O contacts are closed, allowing for the 0-10 Vdc to control the dimming of the load. When Normal Power is lost, the N/O contacts open, breaking the 0-10 Vdc dimming control, bringing the light load to full brightness.

Bypass/Shunt Application

• When Normal Power is present, the ESR Bypass/Shunt relay coil is activated (contacts N/O), and the emergency panel is fed from Normal Power. The lighting load can be switched on/off using an individual wall switch. When normal power drops out, the ESR coil is deactivated and N/C contact falls closed.

When Normal Power is present, the ESR relay coil is activated and the emergency panel is fed from Normal Power. The light-ing load can be switched on/off using an individual wall switch.

When Normal Power drops out, the ESR coil is deactivated and N/C contact falls closed. The Automatic Transfer Switch changes over to backup (generator) power, and the lighting load is illuminated regardless of the position of the wall switch or controller scheme.
