Introduction
The Bosch LBB 6010 is a VHF talk-back receiver designed
for use in DP6000 paging systems and PS6000 personal
security systems.
The unit receives speech and pilot tone transmissions
from suitably equipped mobile transceivers in the field
and processes the signal in to the Paging system.
The unit is housed in a strong plastic casing which is
suitable for wall mounting. A female “N”type connector
is provided for connection to the antenna and a cable
terminated with a 16-pin Hirschmann plug allows
connection to the paging line.
A green LED built into the receiver housing indicates
when the system voltage is present and a yellow LED
indicates when the receiver squelch function is active.
The receiver operates on a frequency between 146 and
174 MHz determined by the crystal fitted.
All external connections on a frequency to the paging
system, including power are via the DP6000 system
paging line.
An additional DP6000 code and DTMF detector circuit
board (LBB 6015/01) can be fitted into the receiver
allowing the processing of the DP6000 paging codes and
DTMF signals. This enables the LBB 6110 receiver to be
used in dial and PS 6000 systems.
In PS 6000 system alarm and status information is
transmitted from the Personal Security Transceivers (LBB
6065 or LBB 6066) back to the central control unit.
In a system with dial transceivers, the DTMF selection
signals are transferred by the central receivers to dial
coupler type LBB 6042 and/or central control.
A built-in monitoring circuit checks the following
functions of the receiver in operation.
a) Supplied system voltage
b) Squelch function, in combination with
pilot tones,or DP 6000 codes, or DTMF signals.
