Troubleshoot Mode

In this mode, system voltages may be displayed on the 4-character display of the PRO-411. An internal voltmeter
measures the voltage present at the channel/inputs, AC power input, battery terminal leads, Notification Appliance
Circuit and resettable 24 volt power. A lack of keyboard activity for a period of 20 minutes will cause the panel to
return to Normal Mode.
To access the Troubleshoot Mode, press the MODE key followed by the digits 8768 and then the [ENTER/STORE]
key.
8768 spells TROU on a Touch-Tone
Once in this mode, the 411UDAC will continue to communicate any events not yet acknowledged at a central station
prior to entering Troubleshoot Mode. The UP arrow, DOWN arrow and 1st EVENT keys do not function in this
mode.
All status displays in Troubleshoot Mode are shown in real-time, which means the display will update automatically
as the status changes. The one exception is the battery voltage which requires pressing the [ENTER/STORE] key to
update the display.
