Viking Electronics E-10A | Entry Phone, Technology Analog, Flush-Mounting, 5 to 95% Humidity Rating, 18 VDC

The E-10A is a telephone line powered door entry phone designed to provide two-way hands-free communication. When the "Call" button is pressed, the E-10A 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-10A can be used with a VIKING K-1900-5 or K-1900-30 dialer or connected directly to a CO line or analog PABX/KSU station when programmed as a ring down circuit. If a line or station is not available, a VIKING DLE-200B ring down circuit can be used. One to four E-10A speaker phones can share an existing entry 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 unit is exposed to precipitation or condensation, use model E-10A-EWP.
