No, none of our analog emergency phones or entry phones are sensitive to polarity of the analog line connected. They have a built in “polarity guard’ that allows them to work in either polarity.
Are the E-1600A series phones or the E-30 series entry phones polarity sensitive to tip/ring for the phone line connection? Print
