User Interface
The LCD display is used to show detailed information about the status of the control system and the
configuration parameters to the user. The keypad (Figure 3-3) is used to select the information displayed and to
enter the configuration parameters, which are stored in the DVP-120 non-volatile memory. The keypad consists
of the usual ten digit keys, the normal four direction keys, plus a MENU key that is used to access the
configuration menu and a HUSH key that will silence the audible alarm indicators.

Figure 3-3 Keypad layout
In normal mode, no warnings or alarms that have not been silenced, the up and down cursor keys will scroll the
display to any configured sensors’ status.
In normal mode, the left and right cursor keys will scroll through all relays’ status. When the left (or right) key
is used to scroll to another relay the display will remove the underlining under the sensor number and underline
the relay number, this indicates that the digit keys can be used to jump directly to a particular relay’s status.
When the up or down key is again used the display will switch back to the digit keys jumping to a particular
sensor.
The MENU key has three functions. First, when the system is presenting the normal display, pressing the
MENU key will cause the system to shift to the Configuration Menu. The second function of the MENU key is
to return to the next-higher menu level, e.g. from the sensor configuration menu to the system menu, or from the
system menu out to normal mode. When the MENU key is used to return to normal mode, any changed
configuration parameters are saved in the DVP-120’s non-volatile memory. The third function of the MENU
key is to change the LCD contrast by holding the MENU key for five (5) seconds, at which point the LCD will
prompt for further activities, see sections 4.4 for more detail..
The HUSH key is only used to silence the audible indicators (internal buzzer and possible external Horn and
Strobe devices). Pressing and releasing the button will silence the internal buzzer. The HUSH button must be
held for 3 seconds to silence the Horn and Strobe devices. See sections 3.1.4, 3.1.5 and 3.1.6 for more detail.
In normal mode, holding the zero key for three (3) seconds can be used to lock the keypad against accidental (or
unauthorized) use. See section 4.5 for details.
