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.

Temperature control and maintenance Heating and cooling system control

Temperature control with GSM phones GTCOM module (thermostat) measure temperature  through a probe (that is on system cable) and can drive any of outputs OUT1, OUT2, OUT3, OUT4 (you can program which) to activate or deactivate the  heating/cooling system  so to keep the temperature required. This is the  way to keep room temperature required.

Temperature range is -40 to 80 degrees Celsius or accordingly Fahrenheit. It is possible to set a low temperature alarm and a high temperature alarm. Passage through these thresholds will trigger alarm SMSs. You can choose a temperature hysteresis. If the temperature is too low or too high the GTCOM sends a warning SMS message, including an actual temperature value and allowing you to take action or a output to be activated to correct the temperature.

For  example  a  user  can  receive  a  reporting  SMS  and  also  switch  output  on  or  off  to  achieve  the  requested temperate. This is quite powerful temperature control system not only for residential use but for professional use also.

If  your  company  sells  heating  on  a  calories  basis,  this  solution  can  help  you  a  lot,  avoiding  energy  waste  and useless trips to a location.

If  you  have  a  house  in  the  mountains  and  want  to  make  sure  temperature  is  kept  correctly,  GTCOM  is  the professional solution to implement this purpose.

Module  can  be  used  to  monitor  industrial  refrigerators,  electrical  transformers  animal  farms  or  any  location  or machine where temperature control is significant
