GSM GATEWAY

INSTALLATION
Since GT20 and GT10 are structurally completely the same and only the number of
channels is different, the installation information below has been given for GT20.
Installation of GT10 can be carried out similarly by making use of that information for
only one channel easily.
PREPARATION
Before starting with the installation of the gateway, the location where the installation
will be performed should be determined according to the criteria below:
1- The wall on which the GT20 GSM Gateway will be mounted should be firm enough
to carry the anchor plugs and it should have a smooth surface.
2- It should be installed in places that are not exposed to direct sunlight with humidity
rate in the range %0-%80, with environmental temperature in the range 0-45°C,
well ventilated, well lit. It should not be exposed to effects of dust, vibration, oil and
water.
3- Devices that generate high frequency waves (such as welding machines, office
equipment such as computers and telex machines, air conditioners, TV sets, etc.)
should not be in the same room if possible, and they should be at least 3 meters
away from the gateway, otherwise.
4- A location with powerful GSM coverage should be chosen. As single line telephones
or telephone systems may be affected by the signal level of the GSM gateway, it is
recommended to select a place for GT20/10 far away from these equipments.
5- The mains supply should be reserved for the module only. The power supply of the
system should be uninterrupted and, if possible, the system should be powered
from an independent source from which no other device is powered.
POWER SUPPLY THAT IS INTERRUPTED FREQUENTLY MAY AFFECT
NORMAL OPERATION OF THE SYSTEM!
6- A location that can be reached easily should be chosen, considering the mounting
work and later maintenance work.
7- There should be an outlet 2 meters away for the adaptor.
8- It is recommended that the lower edge of the module should be 150 cm. above
the
floor.
APPLICATION
In order to mount the GT20 GSM Gateway on the wall, the front cover of the gateway
should be removed. In order to open the front cover, one should split the front cover from
the back one by pressing the latches at both sides of it. (Figure - 6).
Figure-6
After the cover of the module has been opened, the wall mounting can begin. At this
stage, the steps below should be followed.
Normally, it is not necessary to remove the card from the cabinet for the installation.
But if required for any reason, the card can be removed by following the steps in Figure
- 7. Push the latch as “1”, then move the card in direction “2” and remove the card in
direction “3”.
