ELPU

Emergency light power unit

3 are installed in the forward section of the fuselage, and 3 in the rear section. They automatically provide electrical power to the emergency lights under any of these conditions:

• power loss on DC Bus 1
• commanded by the crew (using the EMER LT switch on the Passenger Signs panel)
• in test mode (using the TEST button on the Emergency Light section of the flight attendant panel)
• activated from the flight attendant panel

They enable illumination for at least 10 minutes, and are recharged by DC Bus 1.
