Couplerhead
The Bosch Couplerhead LBB 5843/01 has been designed
for use in DP6000 paging systems.It has been designed to
function as an interface between the LBB 5800 paging desk,
or a PC fitted with the LBB 6000 card,and a number of
contact inputs.When a switch is activated, a pre-
programmed paging call will be transmitted to a receiver.
Each couplerhead has two relay outputs which may be
programmed to fulfil various functions.
The couplerhead is built into a modern plastic casing,
intended for wall mounting.
Up to 32 switches can be connected to the connection
blocks on the PCB of each couplerhead. The paging calls
can be activated by operating the switches.
The contacts of these switches may either be open/closed
constantly or they may open/close just for a moment (pulse
contact).The input circuit consists of optocouplers which
react to 10 mA current loop.
The loop current for the input circuits may be supplied
either internally from the power supply connected to the
couplerhead or by a separate external power supply, in case
complete galvanic separation is required.
The couplerhead is connected to the desk LBB 5800 via the
RS 485 input.Up to 31 units can be connected to this
input.Up to 31 couplerheads may be connected,and
consequently 31 x 32 = 992 contact inputs and 31 x 2 = 64
relay outputs may be programmed.
If the couplerheads are connected to the LBB 6000 card,a
maximum of 31 couplerheads may be connected to the
RS485 port of this card.
Multipurpose coupler software functions of the
LBB 5800 desk
The software of the LBB 5800 desk serves the following
purposes:
Contact inputs
Each contact input may be programmed to be a call input,
presence input or a reset input for a paging call, or it may
be used to start the re-route function.
