The E-20B is a telephone line powered entry phone designed to provide two-way handsfree communication. When the "Call" button is pressed, the E-20B will come off-hook and will remain off-hook until a CPC signal is detected, the programmed timeout has elapsed, a busy signal is detected, or the call goes silent, making the unit automatically disconnect.
The E-20B can be connected directly to a CO line or analog PABX / KSU station when programmed as a ringdown circuit, or used with a Viking Dialer. If a line or station is not available, Viking`s DLE-200B ringdown circuit can be used. One to four E-20B entry phones can share an existing phone line in a house or small business when used with a Viking C-200, C-250 or C-2000B Entry Phone Controller.
For outdoor installations where the entry phone unit is exposed to precipitation or condensation, use model E-20B-EWP.
