If the [*/BACK] key is not pressed during the power-up time-out period, the control panel
resumes operation using the last confirmed status of the affected expander and displays an
installation error condition.

Warning!
Expansion devices such as point expanders and multiplex expanders are disabled if they are
removed from the control panel configuration after installation. You cannot disable supervi-
sion of these devices when they are installed.
For additional information, see the installation instructions for the specific expanders.

Notice!
EEPROM fault at first installation
When the D7039 Multiplex Expansion Module is first installed, the system displays an EE-
PROM fault. Execute the default procedure to synchronize the EEPROM on the expansion
module to the EEPROM in the control panel. Remove power to the control panel, then reapply
power and re-install option bus devices after the default procedure.

Notice!
Loss of programming
Replacing a D7039 Multiplex Expansion Module causes the loss of programming of expansion
points and PINs. Reprogram all multiplex point and PINs if you replace the D7039.
When the D7039 is first installed, or anytime the control panel is powered with a D7039 that
has no points programmed, the system automatically starts the multiplex auto-programming
process:
AUTO PROGRAM?
_______:YES(1) NO(0)
Pressing the [1] key starts auto-programming, and pressing [0/Prog] allows the control panel
to continue normal startup. The menu automatically closes with NO selected if no key is
pressed after several minutes.
For detailed instructions on the auto-programming mode, see Auto Program, 93.
