to your specific alarm panel manual for details on these menus. To activate the case tamper
simply slide the cover up and down, you will hear a click when the case latches are engaging and

Mark the location for the magnet in the frame directly in line with the sensor and drill a ¾ inch by
½ inch hole for the magnet.
