Test the GSM Network signal strength
before mounting the GS3050-A in the
proposed placement.
1
. Remove the screws and the metal casing [
1
].
2
. Drill the anchor screw holes (use the back-
plate to mark the screw locations).
G
Check for cable conduits and water
pipes before drilling.
3
. Lay the cables, then pull them through the ca-
ble entry [
11
].
4
. Attach the backplate to the wall.
5
. Insert the SIM-CARD (see Figure 2a).
G
The SIM-CARD PIN must be disabled.
6.
Complete the connections on the terminal bo-
ard [10].
7
. Fit the antenna [
2
] and connector [

], then clo-
se the
GS3050-A

GS3050-A
terminals
can be found in Table 3.

G
Use shielded cable only for all
connections, with one end connected to
negative, and the other floating.
Connect the Security device telephone terminals
(
L.E.
on BENTEL products) to terminals 3-4 (
L.I.
)
on the
GS3050-A
board and, if required, connect
Terminals 1-2 (
L.E.
) directly to the PSTN line.
The 5 OC Outputs refer respectively to terminals 7-
8-9-10 and 11 (
O1
,
O2
,
O3
,
O4
and
O5
). These
Outputs are programmed at default to signal the even-
ts shown in Table 3. The Output signals and Standby
Polarity (
Normally Open
(

) or
Normally Closed
(

) can be programmed as per requirements.
Each OC Output can close 70 mA maximum
current to negative.
