1.1 Introduction
The VS4500 offers the latest and most innovative way to incorporate PC clock
or GPS synchronized time, voice and data throughout your facility, providing
you with the benefits of improved productivity and reduced maintenance costs.
The VS4500 wireless controller is a sophisticated time, bell and voice
management system that can synchronize all facility wireless clocks to one
accurate atomic time, run a schedule of bells/alerts, initiate live or pre-
recorded voice messages and send alphanumeric messages to LED displays.
Additional features of the VS4500 include an optional PBX interface and
optional hand held microphone.
The VS4500 uses the PC clock as a time source for wireless analog clocks,
wireless digital clocks and wireless alphanumeric displays. The VS4500 can also
be used to synchronize older wired clocks using a special wireless receiver.
Using the connected PC clock or GPS receiver, the VS4500 updates its internal
clock every few minutes and sends a wireless data signal every minute to
provide time synchronization information to all system clocks.
The VS4500 is a powerful microprocessor-based desktop paging system
capable of addressing up to 1000 receivers. It consists of a fully featured encoder with a 2 line by 16-character LCD display
and a numeric keypad mounted in a wall or desk mountable housing.

Installation
2.1 Site Inspection and System Location
Consider the following requirements when planning system installation and choosing a location for the VS4500 and other
system components:
1. If the optional GPS receiver is used, it should be installed where it is exposed to the sky, parallel to the horizon and
unobstructed by trees, power-lines, etc.
If the GPS receiver is installed indoors, mount it at the lower edge of a window, away from Low E glass and exposed to
the sky.
2. Choose a location that is easily accessible in case you need to perform maintenance on the antenna.
3. The transmitting antenna should be located as close as possible to the center of the site and should not be surrounded
by large metal objects that may block the RF signal and decrease the coverage range of the system.
4. The transmitting antenna may be mounted vertically upward, NEVER horizontally.
5. Magnetic Mount antenna (such as VS638) should be attached to a large metal object (like an air duct, metal shelf or
cabinet) to provide it with a proper grounding. It may be mounted vertically upward or downward.
6. Base Station antenna (such as included with VS654 kit) should be secured to a well-grounded metal structure or to a
pole on the roof.
Locate a path for running the coax cable between the antenna and the transmitter such as a riser (if there is no existing
path, create one).
Place the external transmitter in a location that is as close as possible to the roof such as in the penthouse. Keep the
distance between the antenna and the transmitter as short as possible to minimize RF power loss.
2.2 GPS Receiver Installation (optional)
1. The optional GPS receiver can be mounted indoors or outdoors. Outdoors installation is highly recommended for
optimal reception.
2. The GPS receiver should be installed where the distance to the VS4500 is not more than 100’.
3. If the GPS receiver is installed indoor (not recommended), mount it at the lower edge of a window, away from Low E
glass and exposed to the sky.
4. If the GPS receiver is installed outdoors, mount it in a location protected from direct sun or rain.
5. If the GPS receiver is installed outdoors, secure it the structure or to the wall-mounting “L” bracket included with your system
that allows mounting of the antenna on the side of a building or other structure.
6. Connect the GPS receiver to the COM1 serial port and set the serial port to the required settings (see page 16 for more details).
2.3 Magnetic Mount Antenna (VS638) Installation
1. Secure the antenna to an adequate grounding surface, HVAC duct or metal “I” beam. The antenna should be mounted vertically
upward or downward, NEVER horizontally.
2. Choose a mounting location that will provide an adequate grounding surface and free space for RF radiation. If the antenna is
mounted too close to metal or closed heavy concrete walls room, a high VSWR may occur which in the long term may cause
damage to the transmitter.
3. The optional wall-mount “L” bracket allows mounting the magnetic antenna on the side of a building or other structure, providing
the roof’s overhang is not excessive.
Note: The antenna should be located as far from the VS4500 and transmitter as the coax cable allows.
2.4 Base Station Outdoor Antenna Kit (VS654) Installation
1. To achieve maximum performance for your outdoor antenna choose a location that is unobstructed by trees, branches, power-
lines, etc. Never mount the antenna where there is a signal-reflecting surface such as metal, power lines, mirrored glass, etc.
2. Choose a location that is easily accessible in case you need to perform maintenance on the antenna.

9
3. For optimal performance, make sure the antenna is installed at an elevation that will provide sufficient clearance to allow your
antenna to radiate without interference.
4. It is recommended to mount the antenna where the path of the antenna cable is straight and as close as possible to the system
transmitter. Do not coil up 100 feet of coaxial cable when only 20 feet of cable is required. Use a RG-8U coax cable that is
specified as Low Loss to minimize power loss.
5. The antenna may be mounted vertically upward, NEVER horizontally.
6. Install the grounding kit provided with the VS654 antenna kit.
Note: The antenna should be located as far from the VS4500 and transmitter as the coax cable allows.
2.5 VS4500 Encoder and External Transmitter Installation
The VS4500 system encoder can be installed on a wall or shelf. Install a UPS power backup to protect the system from power
outages and surges. If you are using an external transmitter, place it next to the VS4500 and use the data cable provided to
connect VS4500 and the external transmitter.
Once the transmitter and antenna are placed properly, connect them to the VS4500 and the transmitter as follows:
1. If an external transmitter is used, connect the antenna to the RF-OUT terminal at the back of the external transmitter. Connect
the transmitter data cable between the VS101-XX transmitter and the DATA I/O port at the back of the VS4500.
Otherwise, connect the antenna to the RF-OUT terminal at the back of the VS4500.
2. If the optional GPS receiver is used, the internal clock of the VS4500 will be set to the UTC time and the VS4500 will
start transmitting the local time every minute.
3. If the PC time is used, connect the PC serial port to the COM1 terminal and run the TimeSync or VPS software. See
Setting Date and Time from PC section on page 25 or TimeSync section on page 34 for more detailed information.
4. No additional programming is needed for the system to be fully operational. See Advanced System Information
section on page 10 for more detailed information about the VS4500.
Note: Do not place the VS4500 on top of the external transmitter as RF feedback may cause system malfunction.
