Crestron B-G2-FP & B-G3-FP 2 and 3 Gang Faceplates
2 and 3 Gang Faceplates:
B-G2-FP & B-G3-FP
Introduction
Two and three gang faceplates, B-G2-FP and B-G3-FP, are wall-mounted
plastic accessories that allow you to mount the CNX-B2/4/6/8/12 single-
gang keypads in groups of two or three. For more information on the
keypads, refer to latest version of the Operations and Installation Guide
for the Single Gang Keypads, Doc. 8173. The number in the product’s
name corresponds to the number of gangs. Each of these units is
available in three colors (almond, black, and white). The suffix ‘A’, ‘B’,
and ‘W’, respectively denotes color, i.e. B-G2-FPB is a 2-gang black
unit. The 2 and 3 gang faceplates are specifically designed for the
Crestron keypads and will not accommodate third-party decorator-style
components.
Several different metal finishes are also available (must be purchased
separately) for mounting on the plastic faceplates. Finishes include
chrome, brushed gold, polished black, polished brass, polished gold,
stainless steel and primed.
Physical Description
Refer to the illustrations on pages 2 and 3. The faceplate unit consists of
a removable 2 or 3-gang plastic faceplate and a 2 or 3-gang detent plate.
The metal faceplates are slightly larger than the plastic units. Refer to the
NOTE on page 6 for metal faceplate installation instructions.
The number of buttons on a keypad can vary from 2, 4, 6, 8, or 12. Each
button assembly consists of a rear speaker, and a male port (standard
Cresnet network port labeled 24 Y Z G). The port provides operating
power and communications to/from the keypad

Industry Compliance
As of the date of manufacture, the keypads have been tested and found to
comply with specifications for CE marking and standards per EMC and
Radiocommunications Compliance Labelling (N11785).

Setup
Network Wiring
NOTE: When installing network wiring, refer to the latest revision of
the wiring diagram(s) appropriate for your specific system configuration,
available from the Downloads | Product Manuals | Software and Wiring
Diagrams section of the Crestron website (www.crestron.com).
When calculating the wire gauge for a particular Cresnet run, the length
of the run and the power factor of each network unit to be connected
must be taken into consideration. If Cresnet units are to be daisy-chained
on the run, the power factor of each unit to be daisy-chained must be
added together to determine the power factor of the entire chain. If the
unit is a home-run from a Crestron system power supply network port,
the power factor of that unit is the power factor of the entire run. The
length of the run in feet and the power factor of the run should be used in
the following resistance equation to calculate the value on the right side
of the equation.
Resistance Equation
R = Resistance (refer to table below).
L = Length of run (or chain) in feet.
PF = Power factor of entire run
(
or chain
)
.
R < L x PF
40,000 Where:
The required wire gauge should be chosen such that the resistance value
is less than the value calculated in the resistance equation. Refer to the
table below.

NOTE: All Cresnet wiring must consist of two twisted-pairs. One
twisted pair is the +24V conductor and the GND conductor and the other
twisted pair is the Y conductor and the Z conductor.
NOTE: When daisy-chaining Cresnet units, strip the ends of the wires
carefully to avoid nicking the conductors. Twist together the ends of the
wires that share a pin on the network connector, and tin the twisted
connection. Apply solder only to the ends of the twisted wires. Avoid
tinning too far up the wires or the end becomes brittle. Insert the tinned
connection into the Cresnet connector and tighten the retaining screw.
Repeat the procedure for the other three conductors.
Identity Code
Every equipment and user interface within the network requires a unique
identity code (NET ID). Refer to latest version of the Operations and
Installation Guide for the Single Gang Keypads, Doc. 8173, for
procedures on setting the NET ID.
Installation
NOTE: For simplicity, the following procedure is for a 2-gang unit.
Tools/hardware required
2-gang Plastic Faceplate (supplied with B-G2-FP)
2-gang Detent Plate (supplied with B-G2-FP)
(2) Single Gang Keypads (supplied separately), which includes:
Buttons
(2) Dividers
(4) 1 in. panhead phillips screws
(4) 3/16 in. flathead phillips screws
Cresnet network cable (supplied separately)
Phillips screwdriver (supplied by other)
After the Cresnet network wiring has been installed and verified, use the
following procedure to install the keypads in a standard, 2-gang electrical
box (refer to illustrations on pages 7 and 8).
Installation Guide - DOC. 8182 2 and 3 Gang Faceplates: B-G2-FP & B-G3-FP •5

2 and 3 Gang Faceplates Crestron B-G2-FP & B-G3-FP
1. Turn Cresnet system power OFF.
2. Connect the Cresnet cable to the keypads’ Cresnet ports and
the other ends to the control system.
3. Attach the two keypad button assemblies to the detent plate
using the (4) 3/16 in. flathead screws (supplied with keypads).
CAUTION: Excess wire that is pinched between the keypad and
electrical box could short out. Make sure that all excess wire is
completely inside the electrical box and not between the box and the
keypad.
4. Make sure 2-gang unit is oriented as marked with keypads’
arrows at top, and place unit in the electrical box.
5. Attach units using the (4) 1 in. panhead screws (supplied with
keypads).
6. Attach buttons with LED window oriented upward to match
each LED indicator.
7. Attach dividers making sure dividers’ interlock tabs are
oriented correctly (refer to the “Interlock Tabs Example”
illustration on page 8).
8. Attach faceplate (orient with arrow up, make sure it snaps into
place).
NOTE: If you are installing a metal 2-gang faceplate, carefully clean
plastic faceplate mentioned in step 8, (leave no dust or debris on
faceplate), observe alignment, remove adhesive liners from inner surface
of metal faceplate and mount over 2-gang plastic faceplate.
9. Turn Cresnet system power ON.
