AVT2777 UK

The device is so-called "silent" alarm panel, which discreetly notifies the owner of the protected object about the presence of an intruder. Information short messages are used as the information carrier. The device is adapted to cooperation and has been tested with a Siemens C35i phone. Of course, you can use a different model, but the camera used must support AT commands for sending SMSs.
The "heart" of the whole system is the AT90S2313 microcontroller, working with a 4 MHz quartz resonator. The device contains a complete stabilized power supply, so that it can be directly connected, for example, to an automotive installation or to a transformer.

The device is particularly recommended in alarm systems, where "silent" indication of violation of the protection zone is indicated

Selected parameters of the control panel:

• cooperation with a GSM telephone supporting AT commands
• signaling of the protected zone status - SMS messages
• built-in level translator
• built-in stabilized power supply
• the possibility of expansion and change of destination
