Self-Test/Self-Diagnostics (G2)
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 Features
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 the
LED
Indicator
section below for fault reporting details.
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.
LED Indicator
• The red “UNIT ALERT” LED indicates whenever the Self-diagnostics system has detected a fault condition.
Refer to the chart below when the red “UNIT ALERT” LED is blinking:
• The yellow “STEADY STATE” LED indicates that the charger is turned off.
• The red “CHRG ON” LED indicates that the battery is under full charge.
Note:
The “STEADY STATE” and “CHRG ON” LEDs will toggle faster with a discharged battery. A fully charged battery
will cause the yellow “STEADY STATE” LED to be illuminated longer than the red “CHRG ON” LED.
• The green “AC ON” LED indicates that normal AC power is being supplied to the EXIT sign.
Test Button Features
MANUAL TEST – Pressing the test button will switch the unit into battery mode for a set amount of time. The desired
length of the test is determined by the number of times the test button is pressed.
• Pressing the test button once will switch the unit into battery mode for a period of 2 seconds.
• Pressing the test button twice within 2 seconds will switch the unit into 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 the 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.
Use in accordance with local building codes.
