The MobilCom-6 GSM communicator unit is a security device that can be connected to any fire alarm center or burglary alarm center. It is capable of transmitting different alarm center initiated reports to both landline numbers and GSM numbers too. The module has been designed for DTMF Contact ID type communication and reports in real-time as a landline substitute device. The module has an SMS input, enabling it to be configured to send customized SMS-s to a configured telephone number in case of appropriate contact. Each GSM communicator function is configurable separately via SMS. The MobilCom-6 GSM dialer is designed also to be placed in the alarm center's enclosure with its magnetic antenna on top of the metal box. The GSM communicator requires 12-15Vdc voltage - and it is suggested to be connected into the burglary or fire alarm center's 12V battery connection, due to the increased power demand during communication.
The MobilCom-6 GSM dialer has only 2-input pair connections: a two point 12-15Vdc supply input, the Tip-Ring connector, and the industrial GSM modem with SMA auxiliary antenna input. The interface has been designed specifically for different alarm centers, thus it fills the specific bandwidth requirements and it is equipped with noise filtering functionality required by DTMF type data transfers. The interface has been designed for one-way communication, (only for reports) therefore it cannot receive external phone calls. For the same reason, it is not capable of downloading alarm center configurations via GSM line, while mobile and landline calls can be initiated via the device. The SMS input has dual role: in the case of alarm, it can send an SMS to the user's phone or it can be configured to send a ContactID message via SMS to the central monitoring system. The MobilCom-6 GSM communicator communicates the reports via GSM line. It is using driving the industrial GSM modul in voice mode. At present we manufacture the MobilCom-6 GSM dialer also without enclosure, thus we suggest to use the panel only into alarm centers and not using it as a standalone unit.
According to the picture below, the interface has the following connection points and different colored LED signal diodes. The power input marked with "+" and "–" requires polarity dependent power supply labeled on board, which must be between 12-15Vdc. The Phone line and Tip-Ring inputs are polarity-independent. The SMS input can be activated by switching the power input to its negative (ground) point, so usually it is directed by the PGM output of the central alarm center.
If the user activates the Forced SMS input a pre-configured SMS will be sent to the configured phone number. The connection of the aerial is very easy; it has to be connected into the SMA input. Place the aerial a little farther from the module by providing the appropriate signal strength. The increased noise or interference level of the GSM due to a wrong positioning of the antenna can disturb communication. The GSM aerial has to be connected to the module before turning it on, because the GSM module might get damaged when used without a connected aerial. Optionally in case of using the SMS input of MobilCom-6 communicator there are required SMS orders that have to be sent to the GSM module.
The MobilCom-6 GSM dialer can be operated with any microSIM card. The received unknown SMS-s, including the ones sent from the carrier (including the balance check SMS) are forwarded to the first telephone number, if the first telephone number is specified in the configuration. All members of the MobilCom family can operate only with SIM cards that are not protected with PIN codes. Before device use, the PIN code has to be removed from the SIM card. The alarm center is recommended to be configured for Contact ID communication. When the signal is good enough, the reliability of the GSM communication is as secure as the communication on conventional telephone line.The dialing can be only Dtmf type, the pulse-based dialing is not working. The dialed number in alarm center has to be configured in full length international format, beginning with "+" sign and following with country code.
