6.13 POWER UP SEQUENCE

Whenever power is applied to the 4120 FIP panel, or when the 4120 FIP Master Controller
microprocessor has been reset, the 4120 FIP self-tests its memory integrity and verifies
card configurations. Next, the 4120 FIP displays the system startup in progress messages,
followed by a fault condition. Battery fault conditions normally clear automatically.
The green POWER ON LED illuminates immediately after AC power is applied to the 4120
FIP. Make sure that the green LED is illuminated before connecting the battery power
harness.
IMPORTANT
To power up the 4120 FIP, apply 240 VAC to the unit. Wait until the GREEN POWER
ON LED has illuminate; then connect the battery power harness.
To power down the 4120 FIP, disconnect battery power harness; then, turn the 240 VAC
power OFF.
