Provide Convenient Handsfree Communication
The E-10A and E-20B are telephone line powered
entry phones designed to provide two-way handsfree
communication. Both function identically, but are avail-
able in two different housings to better suit the appli-
cation. 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 time-
out 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 Dialer. If
a line or station is not available, Viking's 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 En-
