Planning the Installation
CHAPTER 2 - PLANNING THE INSTALLATION
CHAPTER OVERVIEW
This chapter details how to plan a successful installation, recommended steps, and explains
the hardware and software components of typical setup scenarios.
2.1 PLANNING THE INSTALLATION
Planning the installation is the single most important aspect of a successful installation. In
general, you need to consider the access controller, the door locks, the devices, and the
need for a network. By the time you are ready to install the system, all of the details
presented in the list below should be known. Take a moment to go through them now before
starting your installation.
During the planning phase, you should determine:
What type of authentication is required for your application?
How many doors need to be secured?
What type of device will be on each door? Doors already inside a secure
area might not need the same type or level of security.
If multiple 4G V-Series devices require networking for template
distribution/management, then a dedicated PC is recommended to
administer the system, as well as an RS-485 to RS-232 converter, and
cabling for serial communications or cabling for Ethernet.
Verify that the chosen access controller supports the Wiegand formats
supported by 4G V-Series devices.
Identify all wiring by the signal levels it is to carry. Use separate cables and
conduits for different signal groups to avoid cross talk. Plan to separate them
by these groups:
Power distribution: Wires carry power to devices, door strikes, etc.
Data communication: RS-485, USB, Wiegand, Ethernet, etc.
Signal: Door contact, request-to-exit push button, alarm input, etc.
When planning device placement, determine the distance limitation of each
signal type and use repeaters if necessary.

Planning the Installation
If you have any unresolved issues with the items on this list, contact L-1 Identity Solutions
Technical Support for additional information before beginning any installation.
WARNING
4G Lite devices should be installed by only a qualified
technician. If you are not qualified to perform an
installation task, call L-1 Identity Solutions Technical
Support or contact a qualified installer.
2.1.1 RECOMENDED STEPS FOR A SUCCESSFUL INSTALLATION
Every installation is unique. Sometimes the issues are well defined and can be handled in a
standard fashion; sometimes the issues are very specific and may not be immediately
recognizable.
L-1 Identity Solutions recommends following these steps for a successful installation:
Plan the installation - Choose the type of hardware required, decide if a
network is required, and decide on the location and number of required
devices.
Unpack all items - Unpack all items and check against the packing list.
Install network hardware components - Install the cabling and
components needed to run the system.
Install software - Install the software needed to set up the devices.
Preconfigure device - Connect the device to the USB cable, supply power
to the device, and preconfigure the device.
Mount devices - Mount the devices in their final locations
Power distribution and device hook up - Connect the device wiring via
the back panel.
Power-up procedure - Check the power connections and start the system
safely. Enroll users into the system (for user enrollment procedures).
Chapters 3 through 7 in this document present more information on these steps.

2.1.4 CHOOSING THE INSTALL LOCATION
2.1.4.1 4G V-Flex Lite and CR-Pass
4G V-Flex Lite and CR-Pass devices are designed to mount on either a single-gang electrical
box or on any flat surface. Consult with local professionals regarding any building and safety
codes that might affect your installation. The correct mounting height is shown below.
Factors to consider when determining the position of a device on the wall:
Proximity to other switch plates or fixtures (the device should ideally be
mounted in-line with other plates or fixtures)
Distance from the floor to the top of the device (L-1 Identity Solutions
recommends using a height between 48 and 54 inches).
The device should be mounted on the knob side of the door
Compliance with the Americans with Disabilities Act if in the United States.

Figure 2-1 Correct Mounting Height
2.1.4.2 4G SecureControl
SecureControl devices can be used in combination with any 4G Lite devices (up to quantity of
4) for control of up to 2 physical doors. SecureControl devices are also designed to be
placed on the secure side of the installation. SecureControl must be placed in an area that is
Part # 430-4G-050-00-004
© 2011 - L-1 Identity Solutions Inc. All rights reserved
22
Planning the Installation
accessible only by Administrators and not by users during normal operation. Some examples
of installation options for SecureControl include:
Fastened or securely placed in the ceiling
Wall-mounted
All of the above scenarios are valid given that the location is on the secure side of the
installation.
2.1.5 PLAN DEVICE NETWORK
The 4G Lite devices feature a built-in single-door relay that allows them to control a single
door lock. They can therefore function on their own or as part of a larger access control
system.
System component selection is specific to each installation, but a minimum system would
consist of a 4G V-Series device mounted on or near an access point, an electric lock, and
cabling.
A more complex system might consist of devices at multiple access points (each with an
electric door lock), a multi-point controller, networking, and a PC to run the access controller
and SecureAdmin Lite Server software.
See the diagram below for an example (non-Ethernet) system diagram.

Planning the Installation
Spec
RS-485
100BaseT
Installation of locks and access controllers should be completed according to their respective
manufacturers' specifications and in accordance with all local codes. Final connections to the
device are explained in more detail in Chapter 4.
To avoid externally generated transients, do not run any wires near utility AC power wiring,
lightning rod grounding wire, etc. Grounding equipment is required for ESD protection and
safety.
2.1.6 CHOOSE NETWORK TYPE
If your installation requires the use of network communications, then the choice of cable, the
cable run length, the network topology, and the termination of the network are important
aspects that must be considered. The 4G V-Flex Lite and CR-Pass devices can be
networked using RS-232, RS-485, or Ethernet protocols.
The table below outlines relevant parameters of the RS-485, RS-232, and 100 baseT
Ethernet communication protocols.

2.1.6.1 RS-485
RS-485 has two distinct advantages over the more common RS-232. First, it allows you to
connect up to 31 4G V-Series devices to a PC with an external RS-232 to RS-485 converter
(available from L-1 Identity Solutions). Second, the RS-485 specification allows for cable run
lengths up to 4000 feet (1200 meters) at modest baud rates.
An RS-485 network is required instead of RS-232 if:
Multiple devices must be connected together so that templates can be
distributed among the devices
The installation has only a single device, but it is over 150 feet (45 meters)
from the host PC.

Specification
Recommendation
2.1.6.1.1 RS-485 CABLE SPECIFICATION
4G V-Series devices provide a 2-wire, half-duplex RS-485 interface. The main cable run
should be low capacitance, twisted-pair cable, with approximately 120 ohm characteristic
impedance. Category-5 rated communications cable is used in RS-485 networks and its
characteristics are defined below. This is the recommended cabling for RS-485
communications. The cable connection includes a differential line (A and B) and a GND
connection.
Table 2-2 Category 5 Cable Characteristics
Capacitance (conductor to conductor) <20 pF/ft.
Characteristic Impedance 100 - 120 ohms
Nominal DC resistance <100 ohms/1000 ft.
Wire gauge 24 AWG stranded
Conductors/Shielding >2 pair (shielding is recommended)
2.1.6.1.2 RS-485 CABLE LENGTHS
As outlined in the RS-485 specification, the total length of the communication cable (adding
up all of the segments of the run) should not exceed 1200 meters (4000 feet). Although the
RS-485 specification calls for a maximum cable length of 1200 meters and provides a
maximum baud rate well above that of the 4G device, a more conservative system should be
configured to no more than 1000 meters and run at a baud rate of 9600 bits per second. After
the network is configured and is running in a stable manner, the baud rate can be increased if
faster network communications are desired.
Drops (down-leads, stubs, T-connections, etc.) to equipment are not recommended, but if
required, should not exceed one foot) and should use the same cable recommended above.
On a long stub, a signal that travels down the wire reflects to the main line after hitting the
input impedance of the device at the end. This impedance is high compared with that of the
cable and the net effect is degradation of signal quality on the bus.
2.1.6.1.3 RS-485 NETWORK TOPOLOGY
Communication cables for RS-485 should be laid out in a daisy chain configuration (See
Figure 2-3). Long stubs or drop downs and the star configuration should be avoided because
they create discontinuities and degrade signal quality. The star configuration usually does not
provide a clean signaling environment even if the cable runs are all of equal length. The star
configuration also presents a termination problem, because terminating every endpoint
overloads the driver. Terminating only two endpoints solves the loading problem, but creates

transmission line problems at the unterminated ends. A true daisy chain configuration avoids
these problems.
NOTICE
The device on the end of the network should be
terminated with a 120 ohm resistor.

NOTICE
A Daisy configuration is recommended over a Star configuration.
2.1.6.2 ETHERNET
If your system is to be configured for use over Ethernet, the wiring will be slightly different.
Communication cables for Ethernet logically form a straight line bus but the more devices on
that bus, the less efficient the network becomes due to increased collisions, and the weaker
the signal will get over distance. Repeaters can be used to boost the signal strength;
however, a better solution is to place switches at intermediate positions along the bus. The
most common Ethernet topology in use today is the star configuration with a hub or switch in
the center.
