D7212G
Overview
2.4.4

Command Centers

A maximum of 32 unsupervised command centers can be connected to the system. The available power, number of
supervised command centers, and number of areas that will be used, affect the total number of command centers that can be
connected.
The system can supervise up to eight command centers. The panel transmits a serial device trouble report SDI FAILURE in
2
the Modem IIIa format or TROUBLE ZN D in the BFSK format, if it loses communication with a supervised command
center. More command centers can be added, but only eight can be supervised. Table 5 shows the command centers
compatible with the D7212G Control/Communicator. See Command Center in the D7212G Program Entry Guide (P/N:
4998138538) for complete details on programming command center options.

Keyswitch

Any of the four available areas can be armed and disarmed with maintained or momentary closure devices such as
keyswitches. Point programming determines loop responses and which area a keyswitch controls.
2.4.5

Event Memory

The system uses event memory to store events for each area. The events for an area can be viewed at a D1255 or D1260
Command Center assigned to the area. The panel clears the events for an area from event memory and starts storing new
events when the area is master armed.
2.4.7

Event Log

The system stores from 500 to 1000 events and event modifiers from all areas in its event log. Event modifiers add
information about an event to the log. Some events are always followed by a modifier. For example, the system adds at least
two items to the log each time an area is armed or disarmed, the open (or close) event and an event modifier showing the
previous arming state.
All events and their modifiers can be stored even if the panel does not send a report for them. The log can be viewed at a
command center, printed locally using the D9131A Parallel Printer Interface Module and a parallel printer, or uploaded to the
Remote Account Manager (RAM IV).
See the appendix in the command center's User's Guide for a listing of log events and event modifiers.
2.4.8 EMI & Lightning Transient Protection
The D7212G Control/Communicator maintains the Bosch Security Systems high level of quality and field dependability. It's
design significantly reduces electromagnetic interference and malfunction generally caused by lightning.
2.4.9
