Vandal Resistant Entry Phones with Built-In
Keypad and 125KHz Proximity Card Reader
The K-1770-3 Series entry phones provide a tough and
attractive handsfree phone for commercial, apartment, and
residential door entry or applications requiring a vandal
resistant speaker phone with built-in 125 KHz Proximity Card
Reader. The card reader outputs industry standard 26-bit
Wiegand data, allowing it to be used with a Viking ES-1 door
controller or any controller compatible with 26-bit Wiegand
format. The K-1770-3 Series entry phones are available in
two attractive finishes: "brushed stainless steel" and "oil
rubbed bronze".
When the "Call" button is pressed, the K-1770-3 returns dial
tone. 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 K-1770-3 may be disconnected by pressing
the "Call" button again. The K-1770-3 comes complete with
a standard, flush mount, rough-in box. In addition, an optional
VE-6x7 weather resistant, surface mount box is available (see
