Safety Guidelines
The general safety information in this guideline applies to both operating and service personnel. Specific warnings and cautions will be found
in other parts of this manual where they apply , but may not appear in
this summary. Failure to comply with these precautions or specific
warnings elsewhere in the manual violates safety standards of design,
manufacture, and intended use of equipment. Cellular Specialties, Inc. assumes no
liability for the customer’s failure to comply with these requirements.
Grounding
This amplifier system is designed to operate from 120 V ac @ 1.3A maxpower
and should always be operated with the ground wire properly connected. Do
not remove or otherwise alter the grounding lug on the power cord.
Explosive Atmospheres
This product has an integral circuit breaker , which may cause an electrical flash
if the breaker should reset. T o avoid explosion or fire, do not operate this product
in the presence of flammable gases or fumes.
Lightning Danger
Do not install or make adjustments to this unit during an electrical storm.

Product Description
Cellular Specialties, Inc. (CSI) developed this Bi-Directional Amplifier (BDA) for use
where sufficient signal from local repeater sites to operate public safety
communications devises was unavailable within the building. It is necessary that
sufficient signal be available on the roof of the structure. The BDA is connected to an
external antenna, usually on the roof, and to one or more internal antennas placed
strategically throughout the area where communications service is desired.
The external antenna is usually a directional type such as a “yagi”. Internal antennas
are usually omnidirectional, although various other types may be used for certain
installations. The BDA amplifies both the “uplink” (tranceiver to tower) and “downlink”
(tower to transceiver) signals thus facilitating communications to and from the local
repeater site. There are seven amplification stages on the downlink and seven on
the uplink for a total of +80 dB nominal gain for each link. Gain can be set using the
LCD display and select/up/down switches. There are also LED indicators for power
overload and gain reduction to prevent oscillation.
LED Indicators (located on the User Interface Control Panel)
Warning: The unit has sensed instability due to insufficient isolation
between the inside antenna and the outside antenna, and has
reduced the gain of the amplifier . This is done to prevent oscillation, which can interfere with the handsets in the covered area
and/or the base station.
Fault:(Red) The gain of the unit has been reduced to a minimum in order
to prevent very strong input signals from overloading the
amplifier . The amplifier will attempt to recover from this condition, initially at fifteen second intervals and then at four-minute
intervals.
An automatic amplifier safety shutdown circuit is
also incorporated that will disable the transmitter, to prevent excessive intermodulation and
oscillation, should the uplink or downlink overloads be reached . The amplifier will periodically
attempt to recover from this condition.
The BDA is equipped with an internal interface
connector (RJ-15) designed for use with an
optional remote monitor. A second Connector (RJ-
11) mounted externally is used for remote
monitoring and shutdown. The RJ-11 pin-out is
listed here.
• Pins 3 & 4 will toggle from open to closed
with faults.

Important Installation Notes
• A high degree of isolation must be afforded to prevent any re-generative
feedBack in the system. FeedBack of this nature causes the amplifier to emit a
continuous signal of maximum amplitude and could, in some cases, interfere with
normal operation of the donor site. The use of window mounts or other non-rooftop
mountings antennas should be avoided.
• The Installer should refer to the Safety Precautions, in the following section, for
proper antenna selection and installation
WARNING! AMPLIFIER OR HANDSET DAMAGE MAY OCCUR IF A
HANDSET IS CONNECTED DIRECTLY T O THE BDA OR THE COAX THAT
LEADS TO THE BDA.
Important Safety Information
For INDOOR
use, an
omnidirectional
!
dBi is authorized for use with this
unit. Inside antennas must be
positioned to observe minimum
separation of 120 cm. (~ 4 ft.) from
all users and bystanders. For the
protection of personnel working in
the vicinity of inside (downlink)
antennas, the following guidelines
for minimum distances between the
human body and the antenna must
be observed.
The installation of an INDOOR
antenna must be such that, under
normal conditions, all personnel
cannot come within 120 cm. (~ 4.0
ft.) from any inside antenna.
Exceeding this minimum separation
will ensure that the employee or
bystander does not receive RFexposure beyond the maximum
permissible exposure according to
section 1.1310 i.e. limits for
General Population/Uncontrolled
Exposure.
antenna with a
maximum gain of 3
For OUTDOOR use, a directional
antenna up to a maximum gain of
1 1dBd is authorized for use with this
unit.The outside antenna must be
positioned to observe minimum
separation of 120 cm. (~ 4 ft.) from
all users and bystanders. For the
protection of personnel working in
the vicinity of outside (uplink)
antennas, the following guidelines
for minimum distances between the
human body and the antenna must
be observed.
The installation of an OUTDOOR
antenna must be such that, under
normal conditions, all personnel
cannot come within 120 cm. (~ 4
ft.) from the outside antenna. In all
installations, the antenna should
never be mounted such that the
main beam is directed toward an
area where workers or bystanders
may be present. Exceeding this
minimum separation will ensure
that the worker or bystander does
not receive RF-exposure beyond
the Maximum Permissible
Exposure according to section
1.1310 i.e. limits for General
Population/Uncontrolled Exposure.
