Overview

The Litetronics Emergency Battery Backup unit (EB20) provides 90 minutes of power to fixtures during a power outage. When normal power is available, the unit fully charges and remains in standby mode. Upon power loss, it switches to emergency mode, delivering 20W for a minimum of 90 minutes. Power restoration returns the unit to standby and begins recharging.

The EB20 is the core component of the backup system and requires one of two indicator modules for status indication. Each module offers a different mounting and installation approach:

• EBCM (Emergency Backup Ceiling-mounted Indicator Module): Connects to the EB20 and mounts in a grid panel adjacent to the fixture.
• EBAM (Emergency Backup Adhesive-mounted Indicator Module): For non-grid ceiling applications, attaches via an adhesive strip to a fixture surface or nearby structural element.

Safety Warning and Instructions

When using electrical equipment, always observe basic safety precautions. Read and follow all safety instructions.

• Risk of fire or electric shock: Luminaire wiring and electrical parts can be damaged during installation. Check enclosed wiring and components.
• Risk of fire or electric shock: Installation requires knowledge of luminaire and electrical systems. If unqualified, do not attempt installation; contact a qualified electrician.
• Before installation, ensure AC power to the fixture is off.
• The product's electrical rating is 100-277 Vac. The installer must confirm this voltage is present at the fixture.
• To prevent electrical shock, connect the unit's connector only after installation is complete and before restoring AC power to the fixture.
• Do not use outdoors.
• This unit requires an un-switched AC power source of 100-277 Vac, 50/60Hz.
• Do not allow power supply cords to touch hot surfaces.
• Do not mount near gas or electric heaters.
• Mount equipment in locations and at heights where it is not subject to tampering by unauthorized personnel. Use of accessory equipment is not recommended by the manufacturer and may cause an unsafe condition.
• Do not use this equipment for purposes other than its intended use.
• Use with grounded, UL/ETL listed, dry or damp location rated fixtures.

Compatibility

The EB20 is compatible with Litetronics LED fixtures rated over 80W that also include 0-10V dimming. Below is a list of compatible Litetronics fixtures:

UL924 Statement of Compliance and Compatibility

When used with a sensor-equipped fixture from the Approved List below, the EB20 will bypass and disable the sensor when wired correctly. This ensures the fixture remains illuminated during periods of vacancy when powered by the EB20. Therefore, the EB20 is UL924 compliant.

• Approved Fixtures WITHOUT SENSOR: LHB88 - 148, HBC115, HBC175**T, HBC220**T, HBE150, HBF100-150, HBS100, HOPT2, LHBC105-155, VTCS8
• Approved Fixtures WITH SENSOR: HBS100, LHB88-148
• Unapproved Fixtures WITH SENSOR: HBC115, HBC115**T, HBC175, HBC175**T, HBC220**T
• Unapproved Fixtures: HBC175, HBS150, LHB148HV

EB20 Operating Instructions

• Ensure the EB20 installation includes one of the two indicator modules.
• Upon installation and power-on, the battery begins charging. A green flashing indicator light signifies charging, which takes approximately 24 hours.
• Once fully charged, the green indicator light will be solid, indicating the battery is full.
• A flashing yellow light indicates a detected problem; contact Litetronics for troubleshooting.
• During a power failure, the fixture provides 90 minutes of emergency light. The red light remains solid during discharge and flashes when the battery is low.

Indicator Module Light Reference Guide

1. Green/flashing = Charging
2. Green/solid on = Fully charged
3. Red/solid on = Discharging/emergency mode
4. Red/flashing = Discharging with limited battery life remaining
5. Yellow/flashing on = Error. Contact Litetronics for troubleshooting.

Testing

• The fixture includes an automatic monthly self-testing function, operating at 30-day intervals for 5 minutes and 360-day intervals for 90 minutes. The red indicator light remains on during testing.
• Additional testing and demo mode are available via remote control, part # TR01 (sold separately).

Maintenance

While no routine maintenance is required for the emergency battery backup to function, periodic checks are recommended:

• Visually inspect the charge indicator light monthly; it should be illuminated.
• Test the emergency operation of the fixture monthly for a minimum of 30 seconds.
• Conduct a 90-minute discharge test annually. The LED fixture should operate at up to 20W for at least 90 minutes.

Service

Service should be performed by qualified personnel as indicated above.

Installation - Ceiling Mounted

BEFORE BEGINNING INSTALLATION, TURN OFF POWER AT THE CIRCUIT BREAKER.

1. Choose a location for the Emergency Battery Backup unit and indicator module, recommending placement close to the luminaire input power wires while ensuring the indicator module reaches its desired location. Refer to Figure A.
2. Once the EBB unit is secured, make wiring connections based on the wiring diagrams found on pages 6-7.
3. Mark the desired location for the indicator module on the adjacent ceiling panel. Drill a hole for the indicator to pass through, 1.75 inches in diameter.
4. Compress the spring clamps, pass the indicator module wiring first through the panel until it sits flush with the bottom side. Release the spring clamps to secure the module. Refer to Figure B.
5. Connect the indicator module and unit via the quick connector.
6. Restore power to the fixture. A green flashing light should appear, indicating the unit is charging. An initial full charge may take up to 24 hours.

Wiring Diagrams

Diagram A: When the LED Driver Power is Less Than 20W
Shows connections for AC power (AC-L, AC-N), Ground, Driver (Driver-N, Driver-L), and LED Lamp (LED+, LED-).

Diagram B: When the LED Driver Power is Greater Than 20W and Used With a Dimmer
Shows connections for AC power (AC-L, AC-N), Ground, Driver (Driver-N, Driver-L), LED Lamp (LED+, LED-), and Dimmer connections. Includes connections for Purple (+) and Pink/Gray (-) dimming wires to the dimmer and driver dimming leads. IMPORTANT: The purple and gray dimming wires must be connected to Luminaire or driver dimming wires. CAUTION: For Diagrams B, C, D, Gray & Purple Dimming leads from EB20 Must Be Connected to Driver Dim +/- leads/terminal Blocks. If connection is not made, the LED Array may flicker and shut down after 10 seconds in 99% of cases during emergency mode. In some cases, the EB20 may fail due to overheating. The dimming circuit helps limit higher driver load to 20W.

Diagram C: When the LED Driver Power is Greater Than 20W Used Without Switch and Without Dimmer
Similar to Diagram B, showing connections for AC power, Ground, Driver, LED Lamp, and Purple/Gray dimming wires to the driver dimming leads. Includes the same IMPORTANT and CAUTION notes regarding dimming wire connections.

Diagram D: When the LED Driver Power is Greater Than 20W Used With Switch and Without Dimmer
Similar to Diagram B, showing connections for AC power, Ground, Driver, LED Lamp, and Purple/Gray dimming wires to the driver dimming leads, with provisions for a wall switch. Includes the same IMPORTANT and CAUTION notes regarding dimming wire connections.
