GSM Intelligent Home Security Burglar Alarm System

タイトルまたは説明

The GTCOM transfers messages about events of the security system to the  mobile phone of a user via GSM communication channel. The module receives Contact ID DTMF codes from the dial-up communicator of security control panel, converts them into readable texts and sends SMS message to the mobile phone of a user.
Upon alarm occur, 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 *6 users. The algorithm of message sending is MS1,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.
The module understands when the call is rejected and will not repeat calling. When the module is calling to the users phone, the user can not reject the call at least *5 seconds. Other wise the module will understand that the users number is busy and will try to repeat the call again. In a case the users number is busy in fact, the module will make repetitive calls following the programmed number of calls.  Efficiency of this function depends on interpretation of call control  by  the  operator;  in  some  cases  the  operator   may  wrongly  interpret  the  call  and  thus  the  module  will  make repetitive calls each *0 seconds, following the programmed number of repetitions (by default 3 repetitions) . In such case GSM operator may be changed or simply the amount of DIAL repetitions reduced.
Parameters of the module are set by sending SMS or via PC by using standard mini USB cable and configuration software SERA. In  order  to  activate  voice  listening  it  is  necessary  to  call  from  a  users  telephone  number.  When  calling,  the module  will immediately activate  voice listening, which will last as long as the user  will reject the call or when the  module  will  start  performing  other  commands.  Calls  from  other  telephone  numbers  (of  non-authorized  users)  are ignored.
