AVT2747 B

A modern layout that allows very effective protection of property. After detecting an intruder, the system selects the owner's cell number and notifies him of the alarm criterion. It is then possible to remotely switch on the alarm siren (or other receiver), switch the system to standby or completely deactivate the protection.
The system was designed based on the ATTINY2313 processor and the MT8870 tone decoder. Trigger inputs work with delay as well as without delay. The system can also be controlled from the local keyboard.
