This is the upgraded version of our popular Alarm Kit with a well thought-out PCB layout with ENIG gold-plated pads and blue soldermask on both sides. It uses a high intensity piezo buzzer, panel mount arm/disarm switch, normally open magnetic switch and terminal blocks.

The alarm can be triggered when the “arm/disarm” switch (S1) is pressed in and the magnetic switch is opened by separating the magnet from the base (in situations such as opening a door, closet, window, etc.)

This is a D.I.Y. kit that requires soldering through-hole components on the double-sided printed circuit board. Users with minimal soldering tools can easily assemble this module.
