•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)
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)
•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)
