Working principle

GSM communication module GTalarm (hereinafter the Module) is applied for transferring of GSM SMS messages to the mobile phone of a user. The module GTalarm may be applied for protection of house, garages, cottages, vehicles as well as for access control, gate control, objects' automatization, smart house and temperature control. For premises protection and in many other applications. In the event of burglary, the device, depending on programmed operation algorithm, is able to call or to send SMS to up to 16 users. A user is able to hear what is going on in his vehicle after answering a call or he may make a call by himself. A user is able to receive an SMS with detailed information about status of each protected zone and number of alarm events. The user is able to control the device via SMS messages only if he knows user's password. If a call is being performed from the telephone number not included in the system‘s data base, the call is rejected immediately. The module has system voltage control. If power supply voltage drops below the defined value, a user automatically will be notified via SMS. The SMS message includes voltage of backup battery. The module has external temperature sensor. A user receives information about temperature alarms and restores via SMS messages. The SMS on voltage of the module and ambient temperature is also available. Temperature may be measured in Celsius and Fahrenheit. SMS periodical test ensures communication control of the module. Test sending time is programmable [Test Time]. The test will include all essential information: GSM communication strength, system (car battery's) power supply voltage, temperature and IMEI of the module. Remote Control by Dialing The module compares incoming number with programmed users' numbers and in a case of compliance activates an output or other action and interrupts the call automatically. All parameters of the module should be configured via PC by using software SERA or in remote manner by sending appropriate SMS including password.

The module transfers messages on events of the security system to the mobile phone of a user via GSM communication channel. Upon alarm response of the security system, the module will generate SMS message about alarmed sensors. Door, PIR, Fire etc. SMS message is being sent to a user in-line with a short call. This is to reduce the probability that a user will not observe SMS message. It is possible to send SMS and to call to 16 users. The algorithm of message sending is SMS1,SMS2...SMSn till all SMS messages will be send. After DIAL1,DIAL2....DIALn. All messages are being sent until all users will be notified about the event. Preferred messages and texts of these messages should be defined when programming the module.
