•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.
