 User/Installation manual

  • Integrated GSM module;
  • 4 inputs for door, motion, fire sensor connection;
  • 3 programmable outputs for remote control;
  • Option to arm/disarm alarm system by short free call;
  • 5 users are informed on the protected unit;
  • 250 users able to control the gate or electromagnetic lock by short free call;
  • Info-carrying SMS on the state of each sensor, number of triggers, system mains voltage, GSM signal strength;
  • Option to connect reserve battery;
  • Option to connect siren;
  • Option to connect external mic;
  • Cheap maintenance.
In the case of trespass of the protected area, the device switches the siren on and calls each user in a row. If neither of users answers, GsmAlarm-420 sends SMS to all five users. SMS shows which area was violated and how many times the relevant area sensor was triggered.
Outputs are controllable by entering relevant code with user's mobile phone keyboard (DTMF signals) or sending a relevant SMS to GsmAlarm-420.
In order to open the gate, user calls GsmAlarm-420 number. Then GsmAlarm-420 checks the caller's number in the list of programmed user numbers and in the case of positive find, switches on the gate control device and cancels the call automatically.
GsmAlarm-420 can be controlled from user's phone solely. If unknown number calls, the call is immediately interrupted and user gets a SMS with caller's number.
You can check alarm operation by short call to GsmAlarm-420 number. If GsmAlarm-420 is operative, the calling user gets a short confirmation call.
User is informed by SMS about main power supply fault and its restoration.
All GsmAlarm-420 parameters are programmed remotely, by sending a SMS with relevant contents with password.
