25. Installing additional modules
Before connecting the ISDN / GSM / ethernet / GPRS module to the alarm centre,
disconnect the electric power supply. Firstly, access the installer menu on the alarm
centre. This prevents a tamper alarm from being triggered when the top part is
removed from the base plate. Loosen the housing screws on the lower side of the
wireless alarm centre as shown in the diagram.
Open the top part and disconnect the connecting cable between the base plate and the
top part.
Turn
the top part around and remove the four housing screws (1) on the bottom. Ensure that
you also disconnect the loudspeaker cable and the battery supply cable (2).
Carefully remove the cover of the top part. Be careful when handling the siren
connection and the tamper spring. The PCB of the wireless alarm centre can now be
seen.
