As soon as a preset threshold is exceeded, the VIBRA activates a 3.0 Volt voltage in pin 1 of the USB port.
The voltage is limited by a 470 Ohm resistor. If the alarm is not activated, pin 1 is floating.
If the project requires another kind of alarm, the internal relay in the VIBRA alarm beacon offers a flexible
opportunity to link to other alarm systems. The VIBRA alarm beacon has an extra connection port at the
side (covered with a grey plug). The matching connector has been placed in the battery compartment of
the alarm beacon.
