Viking Electronics VK-E-20B Speaker Phone with Push Button UV Stable Light Gray Plastic Surface Mount Only

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.Physical CharacteristicsColor: Light GrayMaterial: PlasticHeight: 5.5"Width: 4.5"Depth: 1.5"MiscellaneousPackage Contents: E-20B Intercom Sub StationSpade ConnectorScrewsAdditional Information: Selectable auto-answer feature allows remote monitoringProgrammable VOX (mic/speaker) switching speedAdjustable microphone and speaker volumeTwo way handsfree communicationProgrammable maximum call lengthSurface mountable onlyWarrantyLimited Warranty: 1 Year
