LCD KEYPAD
Numeric keys
There are 10 keys numbered 0-9. They are used for entering codes,
programming tasks and retrieving information.
Function Keys
The function keys F1, F2, and F3 allow a task to be performed instantly
without a code being entered. For example, F1 can be programmed so
that a full arm occurs by just pressing this key. They are generally set up
by the installer.
The function key must be pressed and held for 2 seconds or pressed
twice within 2 seconds to perform the task.
Navigation keys
These are marked with an up and down arrow. They are used to scroll
through the menus.
Command keys
These are the 3 keys marked OK, NO and #. They are used for entering
and cancelling commands:
OK: Confirms a command. It is generally pressed once at the end of a
task.
NO: Cancels a command before the OK key is pressed. It is also used
to clear the display.
#: Entered before and between parts of a task. For example, it is
pressed between the hour and the minute when setting the time.
Buzzer sounds
Exit: A continuous beep for the pre-programmed exit time.
Entry: Short beeps for a time programmed by the installer or until
the system is disarmed.
Medical alert: A rapid beep. If there is a communicator and the
report is successfully received by an ARC, it reduces to a slower
beep until a user code is entered.
Reject: 3 slow beeps. This sounds if an incorrect entry is made at
the keypad.
Wrong key: A double beep. This sounds if an incorrect key is
pressed.
Fire Alarm: Beep 3 seconds on, 1 second off. This sounds when a
fire alarm is generated.
System state
The installer can program the system so that the LCD displays
whether it the system is armed or disarmed.
