The E-10A and E-20B are telephone line powered speaker phones designed to provide twoway handsfree communication. Both function identically, but are available in two different housings to better suit the application. When the “Call” button is pressed, the E-10A or 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-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 Hot-Line Dialer. If a line or station is not available, Viking’s DLE-200B ring down circuit can be used. One, or up 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 or C-2000A (respectively) Entry Phone Controllers.

For outdoor or harsh environments, the E-10A/20B are available with Enhanced Weather Protection (EWP). The E-10A-EWP and E-20B-EWP feature rubber gaskets and boots, closed cell foam gasketing, silicon sealed connections, anti-corrosive gel filled tip and ring connectors, as well as urethane encapsulated circuit boards with internally sealed, field-adjustable trim POTS and DIP switches.
