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  automation,  smart  house  and  temperature  control.  For  premisses  protection  and  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 premises 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 systems 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 (System Voltage). 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 Dialling The module compares incoming number with programmed users' numbers and in a case of coincide 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.
