New Features in D9412G/D7412G

2.3. 1

Introduction

Eventually, the D9412G will replace the D9412 and
D9112, and the D7412G will replace the D7412 and
D7212. The suffix "G" indicates the control panel's
ability to detect ground fault conditions. All other
software feature sets that were available in the 9000
Series Control Panels remain the same as in the
D9412G/D7412G.
2.3.2

Ground Fault Detect

For the D9412G/D7412G to detect ground fault
conditions, the Earth Ground Terminal on the control
panels were electrically isolated from all other
terminals. A Ground Fault Detect Enable switch (S4)
was added to the panel and is located just under

Terminal 10, Earth Ground. See Section 3.5.2 Ground
Fault Detect Enable for information on operating this
function.
2.3.3 Added Feature When Using Ground Fault
Detect
When Ground Fault Detect is enabled (S4 closed), Points
1 to 8 can be used for non-powered fire-initiating
devices such as heat detectors, 4-wire smoke detectors,
pull stations, and so on. A D125B Powered Loop
Interface or a D129 Dual Class A Interface Module is no
longer required when connecting the non-powered
fire-initiating devices to Points 1 to 8.
