GE Security NX-8V2 Installation Instructions Manual

g
Introduction
This is the GE NX-8V2-Control Panel Installation Instructions.
Installations should only be done by trained professionals.
Use this document to install the system with default settings
that comply with UL requirements.
To install the keypad, other peripherals, and sensors, refer to
the documentation for those devices.
Installation
There are four slots for board insertions inside the metal
enclosure, two on the top and two on the bottom. These allow
the PC board to be positioned vertically (Figure 1). When you
slide the board between the grooves of the slots, make sure
the terminal strip is toward the front opening (toward you) to
allow for the wire connections.
Note: Install the metal enclosure with the door opening from the top
to bottom.

Table 1 lists wire lengths for one keypad at the end of the
wire. When connecting more than one keypad to the end of
the wire, a higher gauge wire is required.

NX-8V2 terminals
Description
House telephone ring (grey).
Telephone ring (red).
Telephone tip (green).
House telephone tip (brown).
Earth ground. Connect to a cold water pipe or a 6 to 10 ft.
driven rod.
AC input. Connect to a 16.5 V, 40 or 50 VA Class II UL
approved transformer.
If used as a siren output (default), the speaker rating should
be 15 watt at 8 or 16 ohm, or 30/40 watt at 4, 8, or 16 ohms. If
voltage ouput is selected in location 37, this output becomes
voltage output, 12 VDC, 1 Amp maximum load. Note: A 3.3
kohm resistor may be required across the bell terminals
when a 12 VDC siren is used. If no resistor is used, you may
experience voltage leakage into the siren, which will cause
these devices to output a small signal.
Connect to the data terminal on the keypads and the
expanders. Maximum number of devices (keypads plus
expanders) is 32. See Maximum Wire Run table.
Connect to the common terminal on the keypads and the
expanders.
Connect to the POS terminal on the keypads and the
expanders. Individually, this terminal is limited to 1 amp.
Combined, this terminal and AUX PWR+ are limited to 2 amps
total current.
Smoke detector power 12 VDC, 1.5 amps maximum (for those
jurisdictions which allow the Priority zone to be used with
smoke detectors).
Common negative wire of powered devices such as motion
detectors and smoke detectors.
Connect positive wire of all powered devices except smoke
detectors and keypads. Individually, this terminal is limited to
1 amp. Combined, this terminal and KP POS are limited to 2
amps total current.
Connect to one side of zone 8 loop. Connect the other side to
com terminal. Open or short causes alarm. Only zone 8 may
be used for a two-wire smoke detector using a 680 ohm EOL
resistor. Refer to the wiring diagram. Program location 37,
segment 6, option 1.
Common (-) terminal for zones 7 and 8.
Connect to one side of zone 7 loop. Connect the other side to
COM terminal. Open or short causes alarm.
Connect as described for zones 7 and 8. Only zone 8 can be a
two-wire zone. Refer to the wiring diagram for examples.
Connect negative lead of low current device [relay, LED
(install 1kohm resistor in series with LED), etc.] Connect posi-
tive lead of device to COM. Current is limited to 50 mA when
output is negative, and 250 uA when output is positive.
