Addressing Considerations
Be aware of the following considerations when addressing the operating panels:
•
One operating panel can control all BA groups.
•
Regardless of whether communication group number 00 or 01 is used, all operating panels display
the same alarm and/or trouble information. If the sounder comes on for one panel (because of an
alarm, trouble, entry delay alert, etc.), it also comes on for the other panels.
•
When there are several operating panels using the same communication group number, and one of
the operating panels is activated by touching a key or entering an ID code, the other panels are
locked out and display “Keypad In Use, Please Wait”
until the first panel is deactivated. The active
period ends 60 seconds after the last key is pressed. Operating panels using a different
communication group number are not affected.
•
Where there are two BA groups with the same communication group number and with similar
opening or closing schedules, it is possible to generate an Entry alarm unintentionally. An example
is when one person enters the premises and triggers an entry delay for one BA group. Another
person entering the second BA group will not be able to turn off the second BA group because the
operating panel has been locked until the first entry delay expires. An entry alarm may also be
generated when an impatient person does not want to wait for an operating panel to clear before
being able to close. To avoid such unintentional entry alarms, assign one panel to communication
group number 00 and assign the other panel communication group number 01. Any other panel can
be assigned either 00 or 01.
When addressing operating panels, make sure that no two operating panels have the same address (same
group and unit number). Failure to do so may result in a communication clash.
Setting the Address of the Operating Panel
If you are pre-programming operating panels in the shop, DO NOT change the default communication
group number 31 at that time. Wait until the operating panel has been wired to the RS-485 bus in the
premises. Failure to do so results in a communication clash when the control unit is powered up, which can
be corrected only by powering down the control unit and then powering it back up again.
If you desire to address the operating panels at this time, perform the following steps:
Step Action
1 Apply AC power temporarily to the control unit. If the LCD display cannot be read
upon power-up, press [0] and [#] simultaneously and use the middle two keys to the
right of the display to adjust the contrast until the display is readable.
2
Wait for the operating panel to perform the power-on self-test. After this is completed,
the panel displays “ADT INTERACTIVE KEYPAD WAITING FOR COMM.”
3 Press the [1] and [8] keys simultaneously to enter the operating panel program mode.
4 Enter the default code 1 2 3 (or other number if you are not using 1 2 3).
5 Press Change.
6 Enter the new communication group and unit number for this operating panel.
7 Press Quit to exit the program mode. The control unit will recognize the operating
panel if it has been properly addressed.
NOTE
: The firmware level of the operating panel is indicated by the characters at the upper right-hand
corner of the parameter display.
Where an operating panel is being used for access control with an ACIU, its communication Unit number
on the RS-485 bus must coincide with the communication Unit number of the ACIU. An operating panel
being used for access control (Communication Group 0) becomes locked out during the period that any
other operating panel at Communication Group 0 becomes activated, and vice versa.
