D7212G
Overview
2.4.4Command 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 the Modem IIIa2 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.

2.4.5Keyswitch
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.
2.4.5Event 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.
2.4.7Event 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.
2.4.8EMI & 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.
2.4.9Programming
Use either the Bosch Security Systems D5200 Programmer or the Remote Account Manager (RAM IV) to program the D7212G Control/Communicator. Refer to the D7212G Program Entry Guide (P/N: 4998138538) for programming options.
