Loop Type Resistance
Doorphone (loop between the
Doorphone Adapter and the
Doorphone)
NOTE: If a Voice Response Telephone Adapter is installed with the telephone, the measured resistance must be less than 20
Ohms and the maximum cabling distance reduced in half compared to a standard key telephone.
