The E-10A and E-20B are telephone line powered entry phones designed to provide two-way handsfree communication. Both function identically, but are available in two different housings to better suit the application.
The E-10A/20B can be connected directly to a C.O.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, Vikings DLE-200B ring down circuit can be used. One to four E-10A/20B speaker 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. The E-10A-EWP and E-20A-EWP shares all of the features of the E-10A and E-20B in addition to Enhanced Weather Protection (EWP) for outdoor installations where the unit is exposed to precipitation or condensation.EWP products feature foam rubber gaskets and boots, sealed connections, gel-filled butt connectors, as well as urethane or thermal plastic potted circuit boards with internally sealed, field-adjustable trim pots and DIP.switches for easy on-site programming.
