APPENDIX
A.1 Battery Backup Upgrade Installation:
This application note describes the installation of the Battery Backup Unit (BBU) to an
EMR Bi-Directional Amplifier (BDA) system.
The BDA system must be mounted and installed. AC Power (if equipped) to the BDA and
the Battery Backup Unit (BBU) must be disconnected in order to install backup battery.
Open the BBU and attach the Red Positive wire to the battery. Also verify a secure
connection between the Black Negative wire to the battery terminal. Mount the BBU unit
with proximity to the BDA to allow the Battery Backup Cable to span the units.
Apply AC Power (if equipped) first to the BDA then to the BBU. Connect the Battery
Backup Cable between the BDA and the BBU and tighten the connector screws. If any
alarm LEDs light, press the Reset Button on the front of the monitor panel. Monitor the
alarm panel to ensure that the DC Alarm have not been tripped.
A.2 Antenna/Line Monitor Unit Installation
This application note describes the installation of the Antenna/Line Monitor Unit (ALMU) to
an EMR Bi-Directional Amplifier (BDA). One ALMU is required for each antenna port of the
BDA, therefore two ALMU are supplied. Each ALMU unit is marked for either the Uplink or
Downlink antenna port of the BDA. It is assumed that the BDA unit is installed and if
equipped with the battery backup option it is installed and operating as described in
AN5214-A.
During the installation of the Downlink Antenna, install the ALMU unit marked for the
Downlink Antenna between the Antenna and the Coax end (see illustration below). For the
Uplink (DAS) install the ALMU unit marked for the Uplink to the last Antenna at the end of
the Coax. Do not install to any Antenna connected to the DAS via a Line Tap
