6. Operation
Under normal operating conditions, the emergency driver remains in standby mode, continuously charging its internal battery. When the main AC power supply to the fixture is interrupted, the driver automatically switches to emergency mode, powering the connected LED fixture for a minimum of 90 minutes.
Testing the Emergency Function
To test the emergency function:
- Press and hold the TEST SWITCH. This action will simulate a power outage, turning off the normal AC power to the designated fixture and forcing the unit into emergency mode.
- Observe that the connected LED fixture illuminates using the emergency driver's battery power.
- Release the TEST SWITCH. The fixture should return to normal operation after a momentary delay, and the emergency driver will resume charging.
Regular testing is recommended to ensure the emergency driver is functioning correctly.
