• DS9431 Accidental Removal (DS9400M
only): On control panels running firmware
version 2.02 or earlier, if the wires on the
keypad option bus are momentarily shorted for
less than a second, the DS9431 Multiplex
Expansion Module may stop working. If this
occurs, the display will show “MUX NOT
DETECTED” and the Trouble buzzer will
sound. If the */Clear key is pressed, the DS9431
will be uninstalled.
Firmware version 2.03 corrects this problem. If
the DS9431 should fail, a new message, “CALL
FOR SERVICE,” will be displayed along with
the following message, “MUX NOT
WORKING.” Pressing the */Clear key will
silence the Trouble buzzer, but will neither clear
the trouble messages nor uninstall the DS9431.
If “MUX NOT WORKING, CALL FOR
SERVICE” or INST.FLT MX EXP” is
displayed, the control panel should be powered
down by removing AC and standby battery
connections, and then restarted. Doing so will
restore the DS9431 to proper operation. If the
problem is not corrected, please contact
Technical Support at (888) 886-6189.
Make sure that you are at the control panel
site with an available phone line before
calling Technical Support.
To remove the DS9431 after installing firmware
version 2.03, please contact Technical Support at
(888) 886-6189.
• DS9434 Four Point Expander Removal: To
prevent the accidental removal of the DS9434, a
new message “CALL FOR SERVICE,” is
displayed. If you wish to remove a previously
installed DS9434, please contact Technical
Support at (888) 886-6189.

• AC Failure during Automatic Battery Test:
The DS9400 FACP automatically tests the
standby batteries every 180 seconds for two
seconds. The system will now continue normal
operation if an AC power failure occurs exactly
during this two-second battery test window.
Boards shipped before August 31, 1999
must be modified according to Technical
Service Note (P/N: 42363) to ensure that
the battery test runs properly. Affected
boards carry a lot number of 99 or lower
and a date code of 9935 or earlier. Boards
shipped after August 31, 1999 with a date
code higher than 9935 are unaffected. See
Figure 1 on page 3 for the location of the
lot number and date code.

Do not exceed standby current ratings for
the control panel. If the total current drawn
from the smoke power and option bus
power terminals exceeds 1 amp, the
system may not be able to switch to battery
power when AC fails. Current drawn from
NACs and auxiliary power does not impact
battery transfer operation.
