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)
1: If not using the ESRTB Remote Test Button (sold separately), switching methods should be rated for at least 24Vdc. External voltage should not be supplied to this input. No specific current rating is required.
2: To maintain Class 2, a maximum of 45 total test inputs (ESRB and/or ESRN) can be wired in parallel per ESRTB.

Wiring Descriptions
Wire Color Description Notes
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.
BROWN Emergency Hot –
BLUE Emergency Hot Switched to Load Switches out the voltage from BROWN
YELLOW Emergency Neutral or other Phase –
WHITE/BLUE (ESRB) Terminal Screw 4 (ESRN)
WHITE/RED (ESRB) Terminal Screw 3 (ESRN)
Remote Test Input (Class 2, Dry
Contact Input)
When wiring multiple units together, WHITE/BLUE
or Terminal Screw 4 must be a shared common.
Test is performed when Input is CLOSED.
VIOLETS (ESRB)
Terminal Screws 1, 2 (ESRN)
Feedback/Dimmer Contact
(Dry Contact Output)
Switch Input does not test this output.
Output is OPEN when normal power is absent or

Output is CLOSED when normal power is present
and Remote Test Input is OPEN.

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.

Use of Normal Light as Emergency LightOur Emergency Bypass / Shunt Relays are UL924 Listed and suitable for shunting around wall switches in order to turn on emergency lighting in the event of loss of normal utility power.
When the Emergency Light is needed as a Normal Light as well, this application can be applied using this specific relay.
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.

• 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.

Specifications
Notes: • Not rated for use as a UL1008 Transfer Device.
Initial Wiring Verification 1. Turn OFF Normal Power and Transfer Power.
2. Wire relay according to wiring diagram.
3. Energize Transfer Power. Emergency Light should illuminate.
4. Energize Normal Power. Emergency Light will turn OFF.
5. Turn ON Emergency Zone Controller. Emergency Light should
illuminate.
Field Inspection 1. Ensure Normal Power and Transfer Power are energized.
2. Red LED will be illuminated.
3. Turn OFF Normal Power. Red LED will turn OFF. Emergency Light will illuminate.
Shunt Relay ApplicationOur Bypass / Shunt Relays are UL924 Listed and suitable for shunting around wall switches in order to turn on emergency lighting in the event of loss of normal utility power.
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.
