5. Screw the rear of the housing with the correct screws

onto the required assembly location and re-insert the
PCB.

6. Make sure that the alarm centre is disconnected from

the mains. Connect the 4-wire BUS correctly.

7. Once more close the 8-zone expansion module.

4. Wiring

The 4 wires from the communication bus of the central station
are connected at the data BUS as described in the installation
instructions of the alarm panel. Additional modules are
connected in parallel at this BUS. The zone ranges are
differentiated by the addressing of the modules. Please note
that during the connection work, the alarm panel must be
disconnected from the mains. Use the opening on the base of
the module to lay the cable.

5. Programming

To put the expansion module into learn mode, the 12V DC
supply must be connected (from the BUS or a separate supply).
As soon as all detectors have been programmed into the
module („taught“) they are stored permanently, even if there is a
power failure or the power is removed.
As soon as the power supply is connected, the first message
„88“ appears in the display.

To enter learn mode, simply open the tamper switch (remove
the front cover) and then press the „SELECT“ button. The
display now shows: “--“. The module is now in learn mode.

NOTE:

You must leave the learn mode of the expansion module before
removing the power supply.
