Installer's Programming Code

the [✱][8] command by the installer to gain access to
the system in order to enter panel or communicator
program information. The installer's program code may
be changed by the installer.

Arming

Close all protected doors and windows and stop movement
in areas covered by motion detectors.
The "Enter Code To Arm System" message should be on
the LCD display. The system cannot be armed unless the
"Enter Code to Arm System" or "Secure System or Enter
Code" message is displayed.
If Double EOL resistors are being used, 3 different
messages can be displayed when viewing open zones,
Zone Open, Zone Tamper and Zone Fault. Zone Open will
be displayed if the zone is in the alarm state (total
resistance between the zone terminal and common is
11200 ohms), Zone Fault will be displayed if the zone is
shorted, and Zone Tamper will be displayed if the zone is
open.
The "Secure System or Enter Code" message is used to
indicate to the user that a force armable zone is open, and
the partition can still be armed. After the partition is armed,
if the force armable zone is secured it will become an active
zone, and will cause an alarm if the zone opens again.
To program a zone as force armable, see "Zone Options" in
the Programming Manual.
Enter a 4 digit or 6 digit access code. As each digit is
entered the keypad will beep.
• If the access code was entered incorrectly, the
keypad will beep steadily for 2 seconds.
• If the code was entered correctly but the message
"Secure System Before Arming" is on the display,
the keypad will beep quickly followed by a steady tone.
• When the correct code is entered, the "Exit delay in
Progress" message will come on and the keypad will
beep quickly.
If enabled, a timer will appear in the right side of the display
indicating the remaining time in the exit delay. Exit the
premises through the designated exit-entry door. At the end
of the allowed exit time the message on the keypad will
change to "Enter Code to Disarm System". See the
"Installer's Programming [✱][8] Command" section on how
to change the exit time. Also see "Quick-arm" and "At-home
Arm".
If a multi partition access code is entered the keypad will
display the message
(0) TO ARM
< >
(Partition Label)
R
The lower right hand corner of the display will show the
partition status using the letter "R" for Ready, "A" for Armed
and "N" for Not ready.
Use the [<] [>] keys to scroll though the assigned
partitions. Only partitions to which the access code is
assigned will be displayed. The message
(2) TO SELECT
< >
(Partition Label)
R
with the partition status at the lower right hand side of the
LCD.
