2.3Features in D7212G

2.3.1Introduction

The Bosch Security Systems D7212G Control/Communicator provides up to 40 points of protection and supports up to four separate areas. The panel is armed and disarmed by area, and several areas can be armed and disarmed with one menu function. The D7212G uses a built-in digital communicator to send reports to the receiver. A maximum of 32 unsupervised command centers can be connected to the system.

2.3.2Ground Fault Detect

In order for the D7212G to be able to detect ground fault conditions, the Earth Ground Terminal on the control/ communicators had to be electrically isolated from all other terminals. A Ground Fault Detect Enable switch (S4) has been added to the panel and is located just under Terminal 10, Earth Ground. For more information on the operation of this function, see Section 3.5.2 Ground Fault Detect Enable on page 22.
