This chapter explains how to install a V-Station 4G or V-Flex 4G device, how to mount a
wall plate, how to attach a device to a wall plate, and how to make the required
electrical connections to the device.
4.1 INSTALL HARDWARE
4.1.1 WALL-MOUNTING SCHEMES
The V-Station 4G and V-Flex 4G devices are mounted, by use of a mounting plate,
either directly to a wall or to an electrical box recessed in the wall. The V-Station 4G
device can be flush mounted only. The V-Flex 4G device can be either flush or recessmounted on a wall.
2010
The V-Station 4G Extreme devices are mounted, by use of a stainless steel mounting
plate, directly to a wall.
4.1.2 INSTALLING A MOUNTING PLATE
The procedure for mounting a wall plate directly to a wall is as follows:
Hold the mounting plate onto the wall in the desired location, trace the square hole that
will be cut out, and mark the mounting screw locations. Note that for the V-Flex 4G,
the large square hole is at the bottom and for the V-Station 4G the hole is to the
right.
Cut out the square hole with a jigsaw or drywall saw. If the V-Flex 4G device is to be
recess-mounted, cut out a hole in the drywall to accommodate the rear extension on
the device housing.
Drill holes for the nylon wall anchors and install them.
Fish wires through the wall to the square hole.
Align the hole in the wall plate with the hole in the wall.
Fasten the mounting plate to the nylon wall anchors in the wall with the provided
screws.
If the V-Flex 4G device is to be recess-mounted on an electrical box, a double gang box
is required to accept the rear extension of the housing.
If mounting the V-Station 4G device to an electrical box, attach the mounting plate to a
single

gang box and use wall anchors on the remaining four holes for additional security.
To install the mounting plate on to an electrical box, screw the mounting plate to the box
with the provided 6-32 screws.
When installing a recess-mounted V-Flex 4G device, be careful not
to damage the tamper switch, as careless handling can shear it off.

4.1.4 ATTACH DEVICE TO MOUNTING PLATE
4.1.4.1 4G V-STATION AND V-FLEX INDOOR DEVICES
Once all the electrical connections have been made to the device, it can be attached to
the mounting plate as follows:
For the V-Flex 4G, insert the four hooked protrusions on the rear of the device into the
corresponding slots on the mounting plate. Hold the device against the plate and gently
press it in a downward direction to engage the hooks. Insert the star-shaped screw at
the bottom center of the mounting plate and tighten with the wrench provided. Do not
over-tighten.
For the V-Station 4G, hold the device with the top slightly tilted toward you, at about a
30-degree angle to the wall. Hold the bottom of the device against the mounting plate
and lower it so that the two hooks on the bottom of the mounting plate engage the
corresponding slots on the device. When the hooks are properly engaged, the top of the
device can be pivoted up against the mounting plate. It will drop down slightly, locking
itself in the closed position, and should be secured in this position with the star-shaped
screws in the holes at the right and left ends on the bottom of the device. Do not overtighten.
2010
With the securing screws removed, the V-Station 4G device can be pivoted down 90
degrees from the wall, to allow access for making connections, etc. The device can be
removed from the mounting plate by tilting it at an angle approximately 30 degrees to
the wall and gently lifting it up off the hooks on the mounting plate.

4.1.5 CONNECT DEVICE TO POWER SOURCE
The V-Station 4G and V-Flex 4G, and 4G Extreme devices can be powered by 12V-24V
DC power sources, or through a Power Over Ethernet (PoE) injector for V-Station 4G
and V-Flex 4G.
The two options for providing 1 2V power to V-Station 4G and V-Flex 4G devices are by
using an external wall plug-in adapter (Figure 4-7), or through external wiring and a mini
plug (Figure 4-8).
12V power can be provided to 4G Extreme devices only through the 3-Wire back cable
(Figure 4-9).

The V-Station 4G, V-Flex 4G devices both support Power over Ethernet (PoE), using
their RJ-45 Ethernet interface. When these devices are to be powered over Ethernet, an
IEEE 802.3af compliant Active Midspan Injector must be used. Such an injector is not
supplied with L-1 Identity Solutions products. An example of a suitable PoE injector is
Model No. AT-61 01 G from Allied Telesis Inc. (http://www.alliedtelesis.com).
Any such device should carry at least one of the certifications shown below and should
be FCC listed.
Figure 4-11 Power Over Ethernet Connection
Figure 4-10 Certification Marks
2010
Specifications for suitable PoE Injectors for 4G Indoor devices are as follows:
Input voltage: 90-264 VAC, 60 Hz
Input current: 0.4A @ 100 VAC
Output voltage: -48 VDC
Output current: 0.32A
Power: 15.36 W
For Power over Ethernet, RJ-45 pin numbers 4, 5 are considered VB1 (+) positive DC
supply, and pin numbers 7, 8 are VB2(-) DC return.

Detailed RJ-45 pin assignments for PoE are given in Table PoE Pin Assignments, and
the physical location of the pins in the RJ-45 connector.
4.1.6 CONNECT DEVICE TO NETWORK
The V-Station 4G and V-Flex 4G devices support both RS-232/RS-485 and Ethernet 1
0baseT and 1 00baseTX network protocols.
4.1.6.1 ETHERNET NETWORK CONNECTIONS
Figure 4-12 RJ45 Pin Location
2010
Ethernet connections to the device are made through a standard RJ-45 connector on
the back of the device.
4.1.6.2 RS-232/RS-485 NETWORK CONNECTIONS
To connect a device to an RS-232 or RS-485 network, connect the appropriate wires to
the provided pigtail in accordance with the pin-out diagram.
Table 4-1 Pin-out Diagram
October 15 2009 – Installation Guide Draft – Edit Purposes Only Page 55
Installation Guide –April 2010
When connecting the device to the network, the following procedures must be followed:
Use Category 5 cabling with a characteristic impedance of 120 ohms
for RS-485 networks. Category 5 cables with a characteristic
impedance of 100 ohms can also be used, but with lower performance.
Cable manufacturers provide cables with multiple twisted pairs
designed for this type of communication (characteristic impedance is
120 ohm).
Unused pairs within the cable must be terminated with characteristic
impedance (100 or 120 ohm) on both ends.
AWG 24 should be considered as the minimum gauge.
Choose one twisted pair of conductors to use for RS-485 differential
connections, other conductors should be used for Signal Ground (RS485 GND on Weidmuller connection).
2010
The RS-232 to RS-485 converter must support Sense Data to be able
to switch from Send to Receive mode.
Check each device's cabling for ground faults before connecting to an
RS-485 network.
Each device should have pin 3 of the mini-connector connected to
earth ground.
After all devices are configured and connected to the RS-485 network, the baud rate
can be increased to the highest supported rate (some experimentation might be
required).
4.1.6.3 WIRELESS NETWORK CONNECTIONS
After the physical installation, the device can be configured for wireless network
connection. The wireless network can be set up either through SecureAdmin (see
Chapter 7 in the Operator's Manual) or through the front panel of the V-Station 4G
device.
To set up wireless operation through the front panel of a V-Station 4G device, perform
the following steps:
2. Power up the device.
Ensure that the wireless network is functioning.

feet.
4.1.7 SINGLE-DOOR CONTROLLER INSTALLATION
The V-Station 4G and V-Flex 4G devices incorporate an internal relay that enables
them to operate a deadbolt/door strike directly.
October 15 2009 – Installation Guide Draft – Edit Purposes Only Page 57
Installation Guide –April 2010
The internal relay is limited to a maximum current of 170 mA. If the
deadbolt/ doorstrike to be controlled draws more than 170 mA,
damage to the device may occur. If the deadbolt/door strike load
exceeds 170 mA, an external relay must be used, as described
below. Do not use the same power supply to power a V-Series 4G
device and a door strike.
Assuming the current drawn by the deadbolt/door strike is less than 170 mA, the
connections between the V-Station 4G or V-Flex 4G device, deadbolt/door strike, and
power supply for the deadbolt/door strike should be made. Note that a snubber diode (1
N4007 or equivalent) must be connected across the deadbolt/door strike to protect the
DC power supply from inductive kickback.
WARNING
CAUTION
2010
The snubber diode and DC power supply for the deadbolt/door strike
are not supplied with the V-Station 4G and V-Flex 4G devices. The
power supply should be specified in accordance with the voltage and
current requirements of the deadbolt/door strike, but it must be
ensured that the current to operate the dead bolt/door strike does
not exceed 170 mA.
If the current required to operate the deadbolt/door strike exceeds 170 mA, an external
relay must be used in conjunction with the V-Station 4G or V-Flex 4G device. The
external relay must be specified so that its contacts are rated to carry the current
required by the deadbolt/door strike, and that the current required to operate its
energizing coil is within the 170 mA capacity of the V-Station 4G or V-Flex 4G device's
internal relay.
Figure 4-13 Connections for Internal Relay Operation
October 15 2009 – Installation Guide Draft – Edit Purposes Only Page 58
Installation Guide –April 2010
The power supply for the external relay must be chosen to match the operating voltage
and current of the external relay coil, but its voltage must not exceed the V-Station 4G
or V-Flex 4G device's internal relay maximum voltage rating of 250 volts.
The external relay should be connected. Note that snubber diodes (1 N2007 or
equivalent) should be connected across the external relay coil and the deadbolt/door
strike.
