D9412GV2/D7412GV2 Operation and Installation Guide 4.0 Installation

4.4Installing 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 15.

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.

4.5Connecting Earth Ground

4.5.1Terminal 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

1.8mm (14 AWG) to 1.5 mm (16 AWG) wire when making the connection.

Do not connect other control panel

•If a ground fault condition occurs, the keypads display SERVC GND FAULT and the control panel transmits a GROUND FAULT TROUBLE, AREA 1

(Modem IIIa2 format only).

When the control panel recognizes that the ground fault condition is corrected, and remains corrected for between 5 to 45 consecutive seconds, a Restoral Report is sent.

The D9412GV2 and D7412GV2 Control Panels log and print a Ground Fault event as a Trouble Point 256 if communicating in Modem IIIa2 format. If communicating in BFSK format, the control panels generate an Alarm Zone 5 event.

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.

entered in the Area 5 Silent Alarm Relay. When

jumper S4 is in the unlocked (open) position, the

control panel does not detect ground fault

conditions.

1 - With S4 closed, control panel detects ground faults.

2 - With S4 open, control panel does not detect ground faults.
