Caution: 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

To meet UL 864 requirements, enable

Ground Fault Detect.

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 transmits

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 D9412GV3 and D7412GV3 Control

Panels log and print a Ground Fault event

as a Trouble Point 256 if communicating

in Modem IIIa

format. If communicating

in Contact ID format, the control panels

generate a Ground Fault (310) event.

4.5.3 Enabling Ground Fault Detection

To enable Ground Fault Detect Enable, lock (close)

the S4 Ground Fault Detect Pin on the control panel

(Figure 3).

4.5.4 Ground Fault Specifications

Table 6 provides the impedance specifications for

detecting ground faults when any terminal or field

wiring is shorted to ground.

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 the keypads 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.

Releasing the reset pin from the closed position

resets the control panel. The control panel resets all

its timers, counters, indexes, and buffers. Any points

that restore after a reset do not generate Restoral

Reports.
