A  lot  of  security  control  panels  are  able  to  transfer  events  to  the  security  monitoring  stations  via  PSTN  land phone line via Contact ID protocol. These messages help to quickly find out where the event took place and what kind of event is it, e.g. triggered sensor, security system in ARM state, security system troubles, network failure etc.

However a lot of security control panels are not able to send SMS to a user to inform about alarms and other events  of  the  security  system.  To  solve  this  problem  the  module  GTCOM  has  been  developed,  which  can  simulate PSTN   line,  receive  DTMF  Contact  ID  messages  and  convert  them  into  readable  format  as  well  as  to  send  SMS message to a user via GSM network.

Users to receive SMS/DIAL messages

The  number  of  users   -  up  to  16  These  users  are  able  to  receive messages  or/and  calls  after  alarm  response  of  the  security  system  or communication test or system state test messages, which are being generated after  alarm  response  of  the  security  system  or  following  test  messages schedule. The number of users  -  up to 16

Remote  control.  Users  who  are  able  to  control  the  module  via short call.

The number of users  - up to 400 These users are able to control outputs via short call, to activate voice listening and to activate ARM/DISARM mode of the system. Action of the user is free-to-select. The actions to be done by the module,  after  the  telephone  number  having  been  recognized,   might  be  assigned to every telephone number.

The  following  actions  may  be  selected  regarding  telephone  number  of each user:

-  To  activate  outputs  OUT1,OUT2,OUT3,OUT4  optionally

-  ARM/DISARM security system

-  Activate voice listening via external microphone MIC
