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.

The module is compatible with any security control panel, which supports DTMF (tone) dialing and Ademco Contact ID data format according to SIA SDC-05 standard. The GTCOM module 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 premises protection and in many other applications.

The GTCOM module has 7 zones, therefore it can be used to expand zones of the security control panel. 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 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 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 .  The  test  will  include  all  essential  information:  GSM  communication  strength,  system   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.
