14 ProSYS User's Manual
LED Indicators
The six LED indicators found at the upper left provide typical system
indications, as discussed below. Some indicators have additional functions,
which are explained later on.
NOTE:
If required, the system status can be hidden by setting the keypad to Hidden LCD
mode. In this mode, the Arm/ , Ready/ and Bypass/ LEDs do not
function, and the LCD displays ENTER CODE: After entering a valid user code,
the system works in and displays the Normal Operation mode. One minute after
the last operation, the system automatically switches to Hidden LCD mode.
Power/
LED
The Power/
LED indicates system operation.
Condition Description
ON
The system is operating properly from commercial
(AC) power; its backup battery is in good condition.
OFF
The system is inoperative due to lack of power (from
both commercial AC and backup battery); servicing
is required.
RAPID FLASH
(about 4 times per
second)
Indicates a trouble condition, as described on page
66.
SLOW FLASH
(about once every
2 seconds)
Indicates the system is in User Functions mode.
See page 55 for more information on user functions.
NOTE:
If a trouble condition exists, the Power/
LED will flash only when the system is in its
disarmed state. Once the system is armed, a previously flashing Power/
LED will
light steadily.
