There are 4 Emergency Power Supply Units which consist
of :
- Electronic logic and switching circuits,
- A 28VDC/6VDC converter which supplies
electrical power,
- A 6VDC battery which supplies the loads in
abnormal configuration,
- A test circuit which tests the condition of
the battery unit, the logic unit and the related
loads.
ISOLATED EPSU TEST
An individual test on each EPSU must be performed when
the test from the PTP shows a fault on the emergency
lighting network.
This isolated test starts when the test pushbutton is
pushed.
A defective EPSU will cause a red LED to come on and
indicate which part is defective. The green SYSTEM OK
LED indicates a serviceable EPSU.
