ROUTINE TEST CYCLING
1.
Every three (3) months: If there has been no power failure, press and hold the
“TEST”
button for at least thirty (30) seconds to
confirm emergency lamp operation. Release
“TEST”
button to return to battery charging mode.
2.
Once a year: Perform a full battery conditioning cycle by de-energizing the AC circuit to which the unit is connected, and allow
the unit to operate for ninety (90) minutes on battery power. Following successful test, energize AC circuit to begin battery
charging cycle.
REPLACING EMERGENCY LAMPS AND BATTERIES
General
a. De-energize the AC power supply to the unit.
b. Remove enclosure cover.
c. Disconnect positive (+, red) battery lead
