E-10A/E-10A-EWP
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, hand soldered
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.

The E-10A and E-20B are telephone line powered
speaker phones designed to provide two-way
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.
