3. Components Included
The Dual-Lite EV2 package typically includes the following items:
- Dual-Lite EV2 Emergency Light Unit (with integrated LED Bulbs)
- Mounting Hardware
- Instruction Manual
4. Setup and Installation
The EV2 unit is designed for fast and secure wall surface mounting.
4.1. Mounting Location Selection
Choose a suitable wall location that is dry, protected from extreme temperatures, and allows for optimal light distribution during an emergency. The unit should be mounted at a height that complies with local building codes for emergency lighting.
4.2. Physical Mounting
- Carefully remove the front cover of the EV2 unit to access the mounting points.
- Position the unit on the chosen wall location and mark the drilling points through the designated mounting holes.
- Drill appropriate holes and insert wall anchors if necessary, depending on the wall material.
- Securely attach the backplate of the unit to the wall using the provided mounting hardware. Ensure the unit is firmly fixed and level.
4.3. Electrical Wiring
- Before proceeding, ensure that the AC power supply to the installation area is completely disconnected at the circuit breaker.
- Connect the unit to an unswitched 120/277VAC, 60 Hz AC power source. Follow the wiring diagram provided inside the unit or on its packaging.
- Connect the appropriate wires: Line (Black), Neutral (White), and Ground (Green/Bare Copper).
- Ensure all electrical connections are tight, secure, and properly insulated with wire nuts.
- Carefully tuck all wires into the junction box or unit housing and reattach the front cover.
4.4. Initial Battery Charge
After completing the physical mounting and electrical wiring, restore AC power to the unit. The unit's charging indicator light should illuminate. Allow the unit to charge for a minimum of 24 hours before conducting any functional tests. This ensures the Nickel Metal Hydride (NiMH) battery is fully charged and ready for emergency operation.

5. Operating Instructions
5.1. Normal Operation
When AC power is present and connected, the Dual-Lite EV2 unit will be in standby mode. The charging indicator light (usually a small LED on the unit's housing) will be illuminated, indicating that the internal battery is being charged or maintained. The LED lamp-heads will remain off during normal AC power conditions.
5.2. Emergency Operation
Upon an interruption of the normal AC power supply, the EV2 unit will automatically detect the power loss and switch to emergency mode. The integrated LED lamp-heads will immediately illuminate, providing emergency lighting for a minimum of 90 minutes, powered by the internal NiMH battery.
5.3. Testing the Unit
Regular testing is crucial to ensure the emergency light functions correctly when needed.
- Monthly 30-Second Functional Test: Press and hold the 'Test' button (if present on your model) for approximately 30 seconds. The LED lamp-heads should illuminate. Release the button, and the lights should turn off (if AC power is present). If no test button is present, temporarily disconnect AC power to the unit for 30 seconds.
- Annual 90-Minute Discharge Test: Once a year, disconnect the AC power supply to the unit for a full 90 minutes. The LED lamp-heads should remain illuminated for the entire duration. If the lights dim significantly or turn off before 90 minutes, the battery may need replacement or further charging. Reconnect AC power after the test.
6. Maintenance
Proper maintenance ensures the longevity and reliable operation of your Dual-Lite EV2 emergency light.
6.1. Battery Care
The NiMH battery is designed for long life, but its performance can degrade over time. Regular testing as described in Section 5.3 helps maintain battery health. If the battery consistently fails to hold a charge for the required 90 minutes, it may need replacement. Battery replacement should only be performed by qualified service personnel using approved replacement parts.
6.2. Cleaning
Clean the exterior of the unit periodically with a soft, damp cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the thermoplastic housing. Ensure the LED lamp-heads are free from dust and obstructions to maintain optimal light output.
7. Troubleshooting
If your Dual-Lite EV2 emergency light is not functioning as expected, refer to the following troubleshooting guide:
- Problem: Light does not illuminate during a simulated power outage or test.
Possible Solutions:- Check the AC power connection. Ensure the circuit breaker supplying power to the unit is not tripped.
- Verify the battery is properly connected and has had sufficient time to charge (minimum 24 hours initial charge).
- If the issue persists after checking power and charge, the battery or charging circuit may require service.
- Problem: Lights dim or do not last for the full 90 minutes during an annual discharge test.
Possible Solutions:- The battery may not be fully charged. Allow for a full 24-hour charge cycle before retesting.
- The battery may be nearing the end of its service life and require replacement.
- Problem: Charging indicator light is off when AC power is present.
Possible Solutions:- Check the AC power connection to the unit. Ensure it is receiving power.
- The charging circuit may be faulty. Contact customer support for assistance.
