LED Specifications

Cable Connection

AC Power

The AC Power on/off switch is on the left-hand of the PSU which is located inside of the repeater.

AC Connector

AC Terminal of the PSU

The AC terminal is at the left-hand side of the PSU. The repeater has a free-voltage range input of 100-240V AC. The AC connector of the AC cable must be connected to the AC terminal of the PSU, and the other end of the AC cable exits through the AC conduit hole and connects to AC power.

AC Cutout Hole (0.87 in)

External Alarm

External Alarm Cutout Hole (0.87 in)

External Alarm port should be connected only to the fire alarm control panel. The default length of the cable that is provided to connect to an FACP is 6m (19.5ft). The EXT alarm wiring cannot exceed 30m (98.5ft).

External Alarm Description

RF

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)

Battery Backup Port
This port connects to the ADRF-BBS/BBL-24 (24V battery backup unit) via a dedicated cable provided by the ADRF.

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.

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.

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.

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.

Wall Mount

Antenna Separation/Isolation

The separation between the donor and server 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.

RF Repeater Oscillation

To prevent feedback, the donor and server antennas must be separated by an appropriate distance to provide sufficient isolation. Isolation can be attained by separating antennas at 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.
Recommended isolation value is 15dB greater than the user-set gain of the repeater. For example, if the user-set gain of the repeater is 70dB, then isolation of 85dB or greater is required. In the same manner, to utilize the maximum gain of 85dB of the PSR-78-8527, antenna isolation of at least 100dB is required.

DO NOT APPLY AC POWER TO THE BDA UNTIL CABLES ARE CONNECTED TO BOTH PORTS OF THE BDA AND THE ANTENNAS. 

• Prior to equipment use, the device must be registered with the FCC. This can be done through the FCC’s website at https://signalboosters.fcc.gov/signal-boosters

1. To mount on a wall, use the appropriate screws and anchors to attach the BDA to the wall using the four mounting holes with the included wall mount bracket.
2. Ensure that the isolation between the donor antenna and the serving antennas is at least 15 dB greater than the BDA gain.
3. Connect the cable from the donor antenna to the BDA connector labeled “DONOR” and the cable from the serving antennas to the BDA connector labeled “SERVER”.
4. Wire the AC power source to the AC terminal block inside of the wiring compartment of the BDA and secure the line using the appropriate conduit and conduit hub connectors.
5. Power on the repeater by flipping the AC switch to the ON position located on the left side of the PSU.
6. Installation of the BDA is now complete. Adjust the gain controls to suit the specific signal environment through the GUI on your PC.
