The Viking K-1770-3 is a tough and attractive speaker phone designed to provide audio communication and proximity entry. Ideal for apartment and residential door entry applications. The Viking K-1770-3 features a built-in 125 KHz proximity card reader and microphone and speaker volume controls. Selectable auto answer for monitoring and intelligent call progress detection for automatic hang-up when the call is completed. The Viking K-1770-3 proximity card reader outputs industry standard 26-bit Wiegand data, allowing it to be used with a Viking ES-1 door controller or any 26-bit Wiegand compatible controller.
When the “Call” button is pressed, the K-1770-3 returns dial tone, and the keypad may then be used to dial any number. If no touch tone is entered within 8 seconds, CPC is detected, a busy signal is detected, or the programmable maximum call time has elapsed, the K-1770-3 will automatically disconnect. Alternatively, the speaker phone may be disconnected by pressing the “Call” button again.
The Viking K-1770-3 entry phone is designed to be flush mounted using the included rough-in box. Surface mountable using one of Viking’s VE-6X7 Series of Surface Mount Boxes.
