Self-Test/Self-Diagnostics (G2)
Operation
The purpose of this option is to provide Self-testing and Self-diagnostic capabilities to the emergency unit. At
predetermined intervals, the emergency unit will automatically switch into battery mode. Refer to the
Self-Test Feature
section below for timing details. The emergency unit will also perform various Self-diagnostic tests to determine if there
are any faults. Visual signaling will alert maintenance personnel to a fault of the emergency unit electronics, battery,
and/or battery charger. The circuitry continuously monitors the operating condition of the emergency unit and battery
charging circuit/battery supply voltage. Refer to the
LED Indicator
section below for fault reporting details.
Self-Test Feature
• The emergency unit will automatically switch to battery mode every month for a period of 1 minute.
• The emergency unit will automatically switch to battery mode every 6 months for a period of 30 minutes.
• The emergency unit will automatically switch to battery mode every 12 months for a period of 90 minutes.
LED Indicator
Once the unit is properly installed according to the installation instruction sheet and AC power is supplied, the unit will turn
on and the Self-diagnostic test function will initiate. After this, the bi-color LED will indicate the status of the unit.
• A steady green LED indicates that normal AC power is being supplied to the emergency unit and the battery is
charged.
• A blinking green LED indicates that the unit is in battery mode. Refer to the
Test Button Feature
section below for
manual test details.
• A red LED indicates whenever the Self-diagnostic system has detected a fault condition. Refer to the chart below to
determine the fault condition:
Test Button Feature
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 30 seconds.
• Pressing the test button twice within 2 seconds will switch the unit into battery mode for a period of 3 minutes.
• Pressing the test button 3 times within 2 seconds will switch the unit into battery mode for a period of 30 minutes.
• Pressing the test button 4 times within 2 seconds will switch the unit into battery mode for a period of 90 minutes.
RESET – Pressing and holding the test button for 2 seconds will reset the LED to a steady green. If multiple faults are
present, it may be necessary to repeat this procedure for each remaining fault indicated by the blinking red LED.
Use in accordance with local building codes.
