4.4 Installing the Control Panel
1. Place the control panel over the inside back of the
enclosure, aligning the large rectangular openings
of the mounting skirt with the mounting hooks of
the enclosure. Slide the control panel down so
that it hangs on the hooks. Refer to Figure 2, Item
2 on page 14.
2. Remove the tape from the #6 x 1/4-in. screw in
the mounting tab on the control panel. The screw
passes through the mounting tab and into the
skirt mounting hole in the enclosure. Tighten the
screw to secure the control panel in the
enclosure.
3. Connect earth ground to the control panel before
making any other connections. Refer to Section
4.5 Connecting Earth Ground.
4.5 Connecting Earth Ground
4.5.1 Terminal 10
To help prevent damage from electrostatic charges or
other transient electrical surges, connect the system
to earth ground at Terminal 10 before making other
connections. Recommended earth ground references
are a grounding rod or a cold water pipe.
Warning:
Do not use telephone or electrical ground
for the earth ground connection. Use
1.8 mm (14 AWG) to 1.5 mm (16 AWG)
wire when making the connection.
Do not connect other control panel
terminals to earth ground.
4.5.2 Ground Fault Detect Enable
A ground fault is a circuit impedance to earth ground.
The control panel has a ground fault detection circuit
that, when enabled, detects ground faults on
Terminals 1 to 9 and 11 to 32. The control panel also
detects and annunciates ground faults on any device
connected to it.
• If a ground fault condition occurs, the keypads
display SERVC GND FAULT and the control panel
sends a GROUND FAULT TROUBLE, AREA 1.
When the control panel recognizes that the
ground fault condition is corrected, and remains
corrected for between 5 to 45 consecutive sec, a
Restoral Report is sent.
The D7212GV3 Control Panel logs and
prints a Ground Fault event as a Trouble
Point 256 if communicating in Modem IIIa
2
format. If communicating in Contact ID
format, the D7212GV3 generates a
Ground Fault (310) event.
4.5.3 Enabling Ground Fault Detection
To enable the Ground Fault Detect Enable feature,
lock (close) the S4 Ground Fault Detect Pin on the
control panel (Figure 3).

4.5.5 Locking the Reset Pin
Locking the reset pin disables the control panel
(Figure 4). When the control panel is disabled, the
system ignores most keypad commands and points.
CALL FOR SERVICE appears in keypad displays
when the pin is locked down.
On-board relays (Terminals 6 and 7) and off-board
relays deactivate when the control panel is reset.
Terminal 8 has power when the relay is deactivated.
Activation interrupts power at that terminal. The on-
board relay (Terminal 8) remains deactivated when
the reset pin is locked in the disable position.
