Description

This Communicator manages SMS and Central Station transmissions and can simulate the land line in the
event of trouble (land line down) or even substitute the land line completely in areas where the GSM service
is provided and where the land line is not available. It has capability of communicating alarm signals via the
GPRS data network. This capability enables a fast reliable path to central stations equipped with a Sur-Gard
System III or System II receiver. The performance of this Communicator depends greatly on GSM Network
coverage, therefore, it should not be mounted without first performing placement tests of the antenna to
determine the best location for reception (at least 1 green LED should remain lit). The VGSM-120
Communicator has 3 terminals which can be programmed as follows:

Outputs (default setting) which can be activated/deactivated remotely, or used to provide status
indications (problems on the PSTN telephone line; problems on the GSM network; Supervision
Message Missing; Fail To Communicate).

Input lines for speech dialer and SMS dialer activation; these functions can also be used to transmit
status indications. Due to the characteristics of GSM Networks, this Communicator can activate only as
intended and cannot be used as a modem for fax/data transmissions or for teleservice operations.
