Door Box Sensor

The sensor is a device that detects when a circuit is opened or closed. Sensors can be used to detect
events such as the opening of windows or doors. When the sensor is tripped, a tone sounds at a
designated extension. Sensors are not sold by Panasonic; however, they can be purchased separately
from an electronics dealer.
Hardware Requirements
The sensor is attached to the Door Box Adaptor (VB-43701).
Trunk lines connected to the Door Box Adaptor signal the designated extensi on when the sensor
is tripped.
