Default Mode
3.4 Default Mode
To return all program entries, including the upload/download secret password and time, to their factory original set-
tings, perform the following steps only when the system is idle (i.e. the communicator is not active) and there are no
active fire alarms or fire supervisories in the system:
Press the MODE key followed by the 4-digit code 3337 and press the [ENTER/STORE] key.

phone.
If an incorrect key is entered, reenter the proper 4-digit code before
pressing the [ENTER/STORE] key. Within
five seconds, repeat this entry by again pressing the MODE key followed by the 4-digit code 3337 and pressing
the [ENTER/STORE] key. The display will read 3337 while the E

nonvolatile memory (storage area for all pro-
gramming options) is being reprogrammed with the original default settings. When reprogramming is complete,
the display will be blank.
3.5 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.

phone.
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.
Channel/Inputs
Pressing 1 through 4 followed by the [ENTER/STORE] key on the PRO-411 displays the input status of the
selected channel. Listed below are the status display and corresponding nominal threshold voltages, as measured
across B+ and B-, for each zone:
Channel # Normal w/E.O.L. Shorted Open Circuit
1 through 4 (status) nAF
1 and 3 (voltage) 11.5V 0V 12.0V
2 and 4 (voltage) 5.0V 0V 12.0V
Where n = normal, A = active and F = fault (or open).
AC Line
Pressing A followed by the [ENTER/STORE] key will display the AC input voltage as shown below. The fol-
lowing lists the AC line voltage range. The AC Power LED will turn off and the trouble LED will turn on when
the AC line voltage drops below the Low Line threshold.
