AVT2716 A

This simple layout is reminiscent of a typical alarm. The difference is that the violation of the protected zone is not indicated in a visible way. 'Spy' remembers the event that triggered the alarm and allows later checking if someone / something triggered it. An intruder does not know about its existence and can not affect its operation in any way. Reading the system's state takes place after pressing the button, the whole plate is small and easy to assemble.
'Spy' works regardless of the existing alarm system.

The device is particularly recommended as a supplement to the existing alarm system and for all 'suspicious' electronic engineers

Selected parameters:

• sensor - any contact element (microswitch, reed switch, etc.)
• a delay to leave the protected zone
• LED status indication
• power supply - 3 V (lithium battery)
• printed circuit board and documentation included
