Detailed Product Description

-

Features

• 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 users 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 callers 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 users phone solely. If unknown number calls, the call is immediately interrupted and user gets a SMS with callers 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.
