Our PASSIVE SHOCK DETECTOR (P.S.D.) is a patent pending device created to cover up to 50,000 square feet with only one sensor placed INSIDE the alarm panel!
The P.S.D. is a small circuit board that can be added to the alarm control panel prior to shipping. It can also be added to ANY EXISTING alarm system with a closed loop circuit and 12VDC output.
It will detect the LOW frequency that is created at precise moment BEFORE a solid surface is broken. The P.S.D. detects FORCED ENTRY through glass windows, skylights, sliding doors, solid doors , even walls and roofs.
The P.S.D. allows you to create a BLANKET OF PROTECTION around your premises against FORCED ENTRY without having to purchase multiple glass break sensors or individual window sensors. If you have more than 4 windows to protect, the P.S.D. is clearly the better choice.
The P.S.D. is for SINGLE FAMILY HOMES or STAND ALONE buildings only and cannot be used in multi or common wall units as they will sense the neighbors perimeter as if it was yours.
