Self-Test/Self-Diagnostic
Operation
The purpose of this option is to provide self-testing and self-diagnostic capabilities to the EXIT sign. At predetermined
intervals, the EXIT sign will automatically switch into battery mode. Refer to the Self-Test section of this page for timing
details. The EXIT sign will also perform various self-diagnostic tests of the unit. Visual signaling will alert maintenance
personnel to a fault of the EXIT sign electronics, battery and/or battery charger. The circuitry continuously monitors the
operating condition of the EXIT sign and battery charging circuit/battery supply voltage. Refer to Self-Diagnostic section
of this page for fault reporting details.
LEDs
The EXIT sign is provided with a state-of-the art pulse charging system for the battery. The yellow LED (STEADY
STATE) indicates that the charger is turned off. The red LED (CHARGER ON) indicates that the battery is under full
charge. NOTE – the “STEADY STATE” and “CHARGER ON” LEDs will toggle faster with a discharged battery. A fully
charged battery will cause the “STEADY STATE” LED to be illuminated longer than the “CHARGER ON” LED. The
green “AC ON” LED indicates that normal AC power is being supplied to the EXIT sign. The red “UNIT ALERT”
indicates whenever the self-diagnostic system has detected a fault condition.
Self-Test Features
The EXIT sign will automatically switch to battery mode every 28 days for a period of 5 minutes. The EXIT sign will
automatically switch to battery mode every 6 months for a period of 90 minutes
Test Button Features
Pressing the “TEST BUTTON” once will switch the unit into battery mode for a period of 2 seconds.
MANUAL TEST - Pressing the “TEST BUTTON” twice (in rapid succession), will switch the unit to battery mode for a
period of 15 minutes. Pressing the “TEST BUTTON” once while the unit is MANUAL TEST mode will cancel the manual
test and return to unit to normal AC power.
RESET – Pressing the “TEST BUTTON” 3 times will reset the red “UNIT ALERT” LED. If multiple faults are present, it
may be necessary to repeat this procedure for each remaining fault indicated by the “UNIT ALERT” LED.
