To monitor and to protect your house from intruders a new modern device has been developed called Alarm Phone dialer.
You can fix/hook this technologically advanced device anywhere in your house. It’ll enable you to monitor your house at times when you are at work.
The device can be easily hooked at your house for example main door, back doors, windows, garage doors, to get high water alarm, low temperature alarm etc.
This new security system can be activated to call programmed numbers and after pressing ‘Pokreni dojavu alarma’ button the system gets ready to dial and assures that phone call is successfully programmed.
Its programming mode can learn several numbers and after detecting an input on its sensor pin this module can call users to report an unpleasant incident and the users can press pound key ‘#‘ of their mobile to stop the device from calling another number or again.
Check out how to programme numbers on this device, as depicted by Alan Parekh:
1. Press the program button
2. Pick up the phone that is connected to the same phone-line as this device
3. Punch-in first number and then ‘*’ key
4. Punch-in next number followed by ‘*’ key
5. Punch-in the rest of numbers and finally ‘*#’ for example: 061123123*061456456*#
The device uses MT8880 DTMF dialer chip and a PIC 16F84A microcontroller and can learn 64 characters or digits including * and # keys.
