1. INTRODUCTION
PSR-78-8527 bi-directional amplifiers (BDAs) extend the coverage area of radio communications in buildings and
RF shadow environments.
Product Features
-Alarming output to supervised circuits for: antenna, amplifier, power supply, battery, and charger
failure
-Up to 85dB of gain and up to 27 dBm downlink output power per band and up to 24 dBm uplink
output power shared
-Software defined filtering of up to 2 non-contiguous wide band support
1.1 Highlights
Supports both 700MHz and 800MHz Public Safety Frequencies in a single repeater
Supports a total of 2 wideband non-contiguous channels per frequency band (700/800)
Air convection cooling without fans
Sharp Filter Roll-off performance (Wide: 60dBc @ Filter Bandwidth Edge + 1MHz)
Web-based GUI Interface; No 3rd party GUI software required
Web-GUI connectivity via DHCP in host mode
External Alarm Function supporting dry contacts (10 outputs, 1 input)

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.
