INTRODUCTION
Devices in the GS3105 and GS3125 series are GSM communicators which, in the absence of a PSTN line, transmit vocal
or digital alarms to System III or System II receivers, via GPRS. You can have the following items for each series:
— The GS3105-K and GS3125-K kits, including GSM/GPRS communicator, antenna with cable from 2 meters, metal
bracket and PCLINK-PCLINK cable;
— The GS3105-BA and GS3125-BA kits, including GSM/GPRS communicator, antenna with 25 cm wire, casing and PCLINK-PCLINK cable.
— The GS3100-BX kits, including antenna with 25 cm wire and casing.
All information relating to a specific version shall be attested to by reference to the the corresponding code. The word
“Communicator” is being used to describe functions which are common to the various versions.
This manual provides programming and operation of the GSM/GPRS alarm Communicator. If there are any special
installation requirements, the remote ANT-EU outdoor antenna may be used.
This Device is fixed and shall be installed by Service Persons only (service person is defined as a person
having the appropriate technical training and experience necessary to be aware of hazards to which that
person may be exposed in performing a task and of measures to minimize the risks to that person or other
persons). It shall be installed and used within an environment that provides the pollution degree max 2, over
voltages category II, in non-hazardous, indoor locations only. This manual shall be used with the Installation
Manual of the alarm control panel. All instructions specified within that manual must be observed.
