“Siren On”

If car’s battery goes low you will get SMS message:

“Low Battery

If temperature goes  low you will get SMS message:

 “Low Temperature”

All SMS text can be free programmed.

After an alarm SMS is sent GTA module calls to user to notice about alarm.

No additional remotes. Every time you lock your car with CAR SECURITY SYSTEM”S REMOTE “GTAUTO” module turns to ARM mode. You never need to remember to ARM your GSM alarm system separately. It activates at the same time then you lock your car.

Special software “SERA”. It is free and included in set to configure “GTAUTO” module via USB link. Anywhere you are just connecting module to your laptop and configure your GSM SMS alarm system.

Diagnosing and testing of the module. Many times there are something missed to test after installation or not tested properly, so sometimes systems works wrong. With “GTA” GSM alarm system that problem does not exists. Just install “GTA” module and run TEST with special software “SERA” and you will see if it is installed and works properly.

Telephone number identification and protection against fraud. In many GSM alarm systems it is enough to know your GSM alarm number to gain full access to it. There are 3 SMS controllable OUTPUTS and there are NO CHANCES to anybody to control them. Only user can control “GTAUTO” module. If someone else tries to cheat your system – this system simply ignores any call or SMS if it is not USER telephone number.

Remote blocking and control. If your car is stolen just send SMS to turn off fuel pump and no one else can turn on fuel pump again except you. After you block your car you call police.

All SMS text can be freely changed as you wish. You don’t like an alert message text that is sending to you? That’s not a problem. With this GSM alarm system you can change SMS alarm messages text. Simply rename them to your language (if it is not English. English is default language).

Example: You don’t like SMS alert message text “Alarm door”. You can rename, for example, to “Door is opened”.

Voltage monitoring. There are problems when you left car with CAR ALARM SYSTEM activated for a long time – car battery goes low and CAR ALARM SYSTEM simply turns off. If you have GTA module this is not a problem for you. Every time your car’s battery goes to critical voltage you will be alerted by SMS message (“Low Battery”). So if you are alerted that battery voltage is critical remember to run motor for 20 minutes and let generator to charge battery. When battery is charged enough you will be informed by SMS message (“Battery restore”).

Periodical test SMS. User can get TEST messages periodically (00-24 hour’s period time). Just set the period time you want to get TEST messages automatically and you will get them. Example of SMS TEST message:
