Once all emergency lamps have been connected to the unit equipment, apply normal AC power and
charge for 24 hours.
For units equipped with G2 and the tri-color LED indicator: Following installation and after AC power has been supplied,
charge for 48 hours, then press and hold the test button until the LED indicator turns orange. This calibrates the unit
equipment for the proper load.
Operation
The purpose of this option is to provide Self-testing and Self-diagnostic capabilities to the unit equipment. At
predetermined intervals, the unit equipment will automatically switch into battery mode. The unit equipment will also
perform various Self-diagnostic tests of the unit. Visual signaling will alert maintenance personnel to a fault of the unit
equipment electronics, emergency lamp(s), battery and/or battery charger. The circuitry continuously monitors the
operating condition of the unit equipment and battery charging circuit/battery supply voltage. Refer to Table 1 for units
equipped with a tri-color LED indicator. Refer to Table 2 for units equipped with a numeric indicator.
