6. Operating Instructions
Once properly installed and connected to AC power, the emergency driver will begin charging its internal battery. The pilot light on the test switch will illuminate to indicate normal operation and charging status.
- Normal Operation: When AC power is present, the LED fixture operates normally, and the emergency driver's battery charges.
- Emergency Mode: In the event of an AC power failure, the emergency driver automatically switches the connected LED fixture to emergency mode, providing illumination for over 90 minutes.
- Test Switch: Press the test switch to simulate an AC power failure and verify the emergency function. The pilot light indicates the charging status (e.g., green for charged, red for charging/fault).
- Rest Mode: To enter rest mode, press and hold the test switch for more than 3 seconds while in emergency mode. This reduces battery discharge during extended storage.
