Professional Telematic Car Alarm (PTCA) is a homologated device intended for installation in cars and trucks. The terminal performs two most important functions:

• Vehicle anti-theft protection, e.g.: *
  • alarm arming/disarming control,
  • control of opening / closing doors, trunk lid and bonnet,
  • control of the angle of the vehicle inclination (towering),
  • control of signals from additional alarm sensors, e.g. motion sensor, impact sensor,
  • anti-attack function,
  • dual-circuit immobilizer function.

In the event of violation, the alarm siren is activated and the appropriate information is sent via the GSM network.

* Depending on the type of additional safety devices installed.

• Supporting logistic processes and security monitoring options (integration with the alarm monitoring center) through access to a lot of information obtained from the vehicle, e.g.:*
  
  • geolocation of journeys and stops,
  • vehicle speed,
  • information about events, e.g. ignition on/off, door opening,
  • counter status,
  • precise information on all alarm events (protective monitoring).

* Tools supporting logistic processes and the type of security services provided depend on the functionality of the service provider's system.

Information obtained by the PTCA terminal is transferred via the GSM network directly to the end user (via SMS messages) or through the use of a full open communication protocol to the indicated address of the server receiving and processing the obtained data (internet transmission of the GSM network).

The PTCA kit includes:

• Control panel designed from scratch by our engineers.
• Maintenance-free rolling code keyfob (with built-in motion sensor).
• Door opening detection module connected to the lighting lamp, communicating radio (wireless) with the alarm control panel.
• Module containing two disconnection relays and a traffic light relay.
• Cable harnesses, GPS antenna, GSM-GPRS antenna.
• Cabin listening microphone.

• External LED light notifications of alarm status (e.g. armed, disarmed, service status).
• The sound signal after detecting an alarm incident lasts 30 seconds and is turned off.
• Automatic arming of the alarm when the keyfob lacks connection with the control panel.
• Automatic disarming of the alarm when establishing the connection between keyfob and the control panel.
• Programmable auto-arm time function.
• Panic button function. Holding the hidden button in the vehicle cabin, sends the alarm according to the programmed rules (the so-called silent alarm - does not activate the siren). The function does not change the logical state of arming/disarming the alarm.

The terminal allows to program up to four mobile phone numbers, to which information about alarm conditions will be sent as SMS messages, along with the current location of the terminal provided as a link to the Google map. After sending the SMS, the Voice Call function will start - the terminal will  call the defined telephone number.

All information obtained by the PTCA terminal can be transferred using the GSM network (data transmission based on public or private encryption). This is done using a full, open communication protocol. A complete set of information obtained by the terminal at a given moment is sent to the indicated address of the server that receives and processes data. Thanks to this, the PTCA terminal enables integration with any IT system, ensuring the receipt of all data described in the protocol. Recording can be done in several ways.

• Basic parameterization.
  The basic configuration of sending records has been divided into three groups. Different parameters are programmable for each.
  • Ignition switched on:
    • elapsed time since the last information sent (second interval),
    • distance traveled (meter interval),
    • twist greater than XX degrees (turn angle interval).
  • Ignition switched off:
    • elapsed time since the last information sent (second interval).
• Advanced, asynchronous parameterization.
  Incident record. Changes in the status of inputs or outputs result each time in a record being sent with information about incidents, regardless of the status of the ignition switch and main power supply.

Changing individual parameters is possible by:

• Local configuration using the service program by connecting a cable to the terminal.
• Remote configuration via dedicated SMS commands or an application installed on Android phones.
