Notice!
Connect earth ground to the control panel before making any other connections.
5.2.2

Connect earth ground

To help prevent damage from electrostatic discharges or other transient electrical surges,
connect the system to earth ground before making other connections. The
10) indicates the earth ground terminal. Use a recommended earth ground reference, such as
a grounding rod or a cold water pipe. Make the connection using 14 AWG (1.8 mm) to 16 AWG
(1.5 mm) wire.
Notice!
Do not use telephone or electrical ground for the earth ground connection. Do not connect
other control panel terminals to earth ground.
Caution!
Avoid electrostatic discharge. Always touch the earth ground connection with the
!
before beginning work on the control panel.

Ground Fault Detect enable

To meet UL 864 requirements, enable Ground Fault Detect.
A ground fault is a circuit impedance to ground sufficient to result in the annunciation of a
trouble condition.
The control panel has a ground fault detection circuit that when enabled, detects ground
faults on Terminals 1 to 9 and 11 to 30.
If a ground fault condition occurs, the keypads annunciate a ground fault and control panel
transmits a trouble message.
When the control panel recognizes that the ground fault condition is corrected, and remains
corrected for between 5 to 45 consecutive seconds, the control panel clears the fault from the
keypad display and sends a restoral report.
The control panel detects ground fault at ≤ 300 Ω.
Enable Ground Fault Detect and reports
To enable fault detection, use RPS. Set the following parameters:
2016.06 | 08 | F.01U.303.996
Place the control panel over the inside back of the enclosure, aligning the large
rectangular openings of the mounting skirt with the enclosure mounting attachment
hooks. Slide the control panel down so that it hangs on the hooks.
Remove the tape from the #6 x 1/4-in screw in the mounting skirt screw tab on the
control pane.l 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.
