SELF-DIAGNOSTICS SYSTEM OPERATION
(EMERGENCY OPERATION UNITS ONLY)
Normal Power-Up Sequence
At power-up, the red and green LED indicators will alternately flash for one to two seconds. Next, the unit will
go through a “Power-Up Quick Test” with the green LED flashing quickly. If no power-up faults were
detected, the green LED will then flash slowly for up to 36 hours to indicate that the battery is charging. If any
faults were detected during the “Power-Up Quick Test”, these will be indicated by a flashing red LED indicator
(see below for interpretation of flashing sequences). The red LED may be accompanied by a buzzer. This
buzzer may be disabled by a short press of the test switch or by the “SILENCE ALARM” button on the remote
tester and will remain disabled for a period of 196 hours. After the fault has been corrected, the red LED flash
and buzzer will be cleared automatically and the unit will return to normal operation except in the case of lamp
failure. Once relamping has been completed, perform a manual test to clear the fault.
Emergency Operation
Emergency operation occurs when AC power fails. The unit remains in this mode until AC power is restored.
During emergency operation, both red and green LED indicators are disabled. Upon restoration of AC power,
the green LED will flash for up to 36 hours to indicate that the unit is in battery charging mode. Allow 72 hours
for the battery to fully charge.
User Interface
Green LED Indicator
Steady On – AC power is present and battery is fully charged
Slow Flash – Battery charging
Fast Flash – Unit is performing an automatic or manually initiated self-test
Red LED Indicator
Single Flash – Battery fault
Double Flash – Lamp failure
Triple Flash – Charger fault
Quad Flash – Emergency transfer failure
(If more than one fault condition is present simultaneously, the red LED will flash each fault pattern in
sequence, and then repeat)
Red and Green LED Indicators Together
Slow flashing red and green – Low line voltage
Fast flashing red and green – High line voltage
Pushbutton Test Switch
Long Press (over 0.5 seconds) – Transfers unit to emergency (battery) operation as long as button is
depressed
Short Press – Initiates various self tests
o
One Press – Cancel any self-test currently running
o
Two Presses – Start 1 minute self-test
o
Three Presses – Start 90 minute self-test
o
Seven presses – Forces a complete system reset
(The unit will allow up to seven 1 minute tests during the first 24 hours of operation. Allow at least 24
hours for battery charging before performing any extended amount of testing)
Buzzer – Sounds in unison with the flashing red LED if a fault is detected. May be disabled for up to 196 hours
by a short press of the test switch.
