1.4 Warnings and Hazards
Opening the PSR-78-8527 could result in electric shock and may cause
severe injury.
Working with the repeater while in operation, may expose the technician to
RF electromagnetic fields that exceed FCC rules for human exposure. Visit the
FCC website at www.fcc.gov/oet/rfsafety
to learn more about the effects of
exposure to RF electromagnetic fields.
WARNING! EXPOSURE TO RF
Operating the PSR-78-8527 with antennas in very close proximity facing
each other could lead to severe damage to the repeater.
WARNING! DAMAGE TO REPEATER
Actual separation distance is determined upon gain of antenna used.
Please maintain a minimum safe distance of DL: 25 cm, UL: 60 cm while operating near the donor and
the server antennas. Also, the donor antenna needs to be mounted outdoors on a permanent
structure. In accordance with the FCC regulations, this device must meet 5W ERP requirements.
To satisfy this, the antenna cable name we propose is LMR200, If available and the antenna length
must be at least of 6.8m (antenna cable loss at 6.8m is about 2 dBi). If you use another antenna cable,
the cable loss must be considered to more than 2 dBi for UL. So, the maximum antenna gain after
accounting for any cable losses should be up to UL: 14 dBi, Panel antenna.

3.2.3 RF
Figure 3-7 RF Ports
The RF connections are made via two 4.3-10 female connectors. The RF connector labeled “DONOR” must be
connected to the antenna pointing towards the base station. The DONOR port can receive both 700 and 800MHz
public safety signals. The RF connection labeled “SERVER” must be connected to the antenna facing the area to
be covered by the BDA. The repeater has a single SERVER port that supports both 700 and 800MHz public safety
signals.
The RF connections must be made using cables with an impedance of 50 ohms.
The separation between the antennas is necessary to prevent oscillation. Oscillation occurs when the signal
entering the system continually re-enters, due to the lack of separation between the donor and server antennas.
In other words, the signal is being fed back into the system. This creates a constant amplification of the same
signal. As a result, the noise level rises above the signal level.
To prevent feedback, the donor and server antennas must be separated by an appropriate distance to provide
sufficient isolation. Isolation is attained by separating antennas a sufficient distance so that the output of one
antenna does not reach the input of the other. This distance is dependent on the gain of the repeater.
DONOR –4.3-10 female which is used to connect the donor antenna (700MHz + 800MHz PS)
DONOR_CPL (30dB) –SMA female 30 dB coupling port which is used to monitor the output of UL signal
SERVER_CPL (30dB) –SMA female 30 dB coupling port which is used to monitor the output of DL signal
SERVER –4.3-10 female which is used to connect the server antenna (700MHz + 800MHz PS)

3.2.4 Battery Backup Port
This port connects to the ADRF-BBS/BBL-24 (24V battery backup unit) via a dedicated cable provided by the
ADRF.
Figure 3-8 Battery Backup Cut-out hole (0.87 in)
When the ADRF-BBS/BBL-24 is connected to the repeater, the battery switch on the PSU must be switched to
the ON position. This will enable the repeater to charge the ADRF-BBS/BBL-24 battery backup unit when AC
power is present.
Figure 3-9 Battery Switch
Connect the ADRF-BBS/BBL-24 to the PSR-78-8527 via the external battery port to provide continuous power to
the repeater during a power failure.
(WARNING: The circuit breaker switch on the ADRF-BBS/BBL-24 must be set to OFF before connecting it to
the PSR-78-8527 to prevent damage to the repeater or the ADRF-BBS/BBL-24 and personal injury.)
Note: Please contact ADRF Technical Support for assistance if you are unfamiliar with the installation procedure
of the battery box.

3.2.5 Grounding
The grounding terminal is located at the lower right-hand side of the BDA. A grounding cable should be properly
connected before powering on the equipment.
Figure 3-10 Ground Cable Terminal
Ground terminals located on the side of the repeater and can support a ground cable up to 1.25mm²(16AWG)
in diameter and should be permanently connected to a grounding bar.
