The Display and Control Center (DCC) Event Handling
System Events Format
When a system trouble occurs, a message, generated by the control panel, displays at the top of the
LCD-160’s screen, while soft keys display available functions that may be used to handle the event.
The top four lines contain event information, and are formatted as follows:
The system trouble event example screen below shows a ground fault condition.
Figure 8.2 System Event Display Example
The event counts section shows the counts for outstanding events. The date in line eight gives the
current time. The soft keys may be used to deal with the event; their functions are described in
Section 9.2.
8.2 The Display and Control Center (DCC)
A Display and Control Center (DCC) is a display location which can respond to events occurring at
other participating locations. While there may be multiple Display and Control Centers on a
network, an individual location can only accept the commands of one DCC at a time. The user’s
actions at any participating station, panel, or remote display determine which location will be the
DCC.
An LCD-160’s DCC participation is set at the fire panel. If the panel associated with an LCD-160
has been programmed to participate in the DCC, all remote displays with Local Control ON will
automatically participate. Refer to the panel programming manual for more information.
When an LCD-160 is not the DCC, pressing Signal Silence, System Reset, Acknowledge or Drill
will automatically send a permission request to the current Display and Control Center (Figure ).
The DCC must release control to the requesting LCD-160 before the command can be processed
