• While the Door Opener is functioning, a call from another Doorphone on the same Doorphone
Adaptor cannot be answered.
Considerations
• The trunk connected to the Doorphone Adaptor must be set to dial pulse (DP).
Doorphone 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 Doorphone Adaptor (VB-3473UK).
• Trunks connected to the Doorphone Adaptor signal the designated extension when the sensor is
tripped.
Considerations
• The trunk connected to the sensor must be a dial-pulse (DP) trunk.

• Panasonic’s proprietary key telephones
• Standard analog devices
• Dial Pulse (DP) / Dual Tone Multifrequency (DTMF) Single Line Telephone (SLT)
