DESCRIPTION
The engineer-friendly
GS3050-A
analogue inter-
face provides total confidence in all security and
surveillance applications. It can be simply and
cost-effectively intergrated with all alarm sy-
stems, and can substitute the PSTN line comple-
tely, in zones where the GSM Service is provi-
ded, and where hardwired telephone devices
cannot be installed (mountain cabins, beach bun-
galows, etc.).
The
GS3050-A
manages two-way voice and
Central station communications, and all the tele-
phone-control functions normally provided by te-
lephone diallers.
The performance of this device greatly depends on
the selected GSM Network, and signal strength.
The
GS3050-A
supports
CONTACT ID
,
10 bps,
20 bps
protocols and, in areas with optimum si-
gnal strength,
SIA
and
CESA protocols
, all of
which transmit properly over the GSM Networks.
The GSM signal strength is of utmost importance,
the GS3050-A should not be located in places
where the GSM signal is weak (e.g. only one
signal strength LED ON), as communications will
be at risk.
The
GS3050-A
can manage up to 8 SMS Texts,
and provides a remote control feature that will al-
low Users to turn ON the 5 Outputs over the pho-
ne.
Due to the characteristics of GSM Networks, the
GS3050-A
cannot be used as a modem for fax or
data transmission, or for Teleservice operations.
The
GS3050-A
is housed in a tamper-protected
metal casing, with built-in status display.
INSTALLING THE GS3050-A
The
GS3050-A
should be located in a safe dry
place, away from radio transmitters and similar
devices. When choosing the placement, remem-
ber that the
GS3050-A
requires a 13.8 V
_
/1 A
min. power supply (usually from the Security sy-
stem).
The
GS3050-A
must be Earthed, and equipped
with standby battery (see Figure 4).
