Introduction
The UHF paging transmitter LBB 6019/xx is designed for
indoor use in a Bosch DP6000 digital paging system.
The transmitter has an output power of 50 mW. Its aerial
output is fully protected against damage caused by short-
or open circuits when transmitting at maximum ambient
temperatures for long periods of time. Full galvanic
separation between system earth, antenna earth and sync.
earth is available during installation.
The transmitter's frequency depends on the crystal unit
used in the transmitters high frequency section and
should be selected within the range 409-470 MHz. For a
full list of available frequencies refer to the relevant data
sheet. Transmitter can be used in 3 and 4 wire DP6000
systems.
Power supply
An external power supply unit (12 V, 2.5 A) is included in
the delivery of the transmitter.
There is also a power outlet available (12 V, 400 mA) that
can be used to supply a central receiver, master sync unit
or desk situated close to the transmitter.
Synchronization
If one transmitter cannot cover the required transmission
area,subsequent transmitters can be installed in the same
system.All transmitters installed in the system can be
synchronized via a pilot frequency from a master sync
unit. An extra pair of wires is required between the
master sync. unit and transmitters to carry the pilot
frequency.
LED indications
Through the metal plate two LED's indicate the
following:
- Power on (green LED)
- Transmitter on (yellow LED),
Internally 4 diagnostic LED's are available indicating the
following:
- LF signal
- RF Power OK
- VSWR Error
- LF sync. OK
