NX-8V2 Control Panel Installation Instructions
Introduction
This is the 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.
P/N 466-2339 • REV B • 02MAR11
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 below).
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 below 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

T Telephone tip (green).
T1 House telephone tip (brown).
AC AC input. Connect to a 16.5 V 40 or 50 VA Class ll UL
approved transformer.
EARTH Earth ground. Connect to a cold water pipe or a 6 to 10 ft.
driven rod.
Bell + and
Bell - 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.
KP Data 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.
KP COM Connect to the common terminal on the keypads and the
expanders.
