The E-10A-EWP is a telephone line powered entry phone designed to provide two-way handsfree communication. When the “Call” button is pressed, the E-10A-EWP 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-EWP can be used with a Viking K-1900-5 or K1900-30 dialer, or connected directly to a CO line or analog PABX / KSU station when programmed as a ringdown circuit. If a line or station is not available, a Viking DLE-200B ringdown circuit can be used. One to four E-10A-EWP 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 is equipped with Enhanced Weather Protection (EWP), ideal for outdoor installations where the unit is exposed to precipitation or condensation. EWP products are designed to meet IP66 standards and may feature foam rubber gaskets, sealed connections, gel-filled butt connectors, as well as potted circuit boards with internally sealed, field-adjustable trim pots and DIP switches for easy on-site programming.
