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 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 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.Technical InformationHandset: NoFeatures: Hands-freePower DescriptionInput Voltage: 18 V DCPhysical CharacteristicsColor: BlackMaterial: Aluminum, Stainless SteelForm Factor: Flush Mount, Surface MountDurability: Vandal Resistant, Weather ResistantHeight: 5"Width: 5"Depth: 2.2"MiscellaneousPackage Contents: Emergency Speakerphone w/ Call Plastic Rough-In Box Additional Information: Intelligent call progress detection for automatic hang-up on CPC, silence, busy signal, or time out Telephone line powered Adjustable microphone and speaker volume Programmable maximum call length Selectable auto-answer feature allows remote monitoring Programmable VOX (mic/speaker) switching speed Speaker Volume: Approximately 70db maximum @ 1m Application/Usage: Residential Intercom, Commercial Intercom, Industrial IntercomCompatibility: Viking Electronics Door Entry Controllers: C-200 C-250 C-2000B Viking Electronics Single Line Paging Controllers: SLP-1 SLP-4 Viking Electronics Tone Dialers: K-1900-5 K-1900-30 WarrantyLimited Warranty: 1 Year
