When a visitor accesses the entry phone, simulated dial tone is heard. After the visitor enters the appropriate one to
three digit tenant number, the K-1900-3 speed dials the tenants phone number and bridges the phone line to the entry
phone. If an unprogrammed tenant number is entered, a simulated fast busy signal will be heard on the entry phone.
When the tenant confirms the visitors identity, a one or two digit relay activation code may be entered from the tenant’s
phone. Two beeps will indicate that a valid activation code has been entered. A buzzing sound is then heard on the
entry phone to indicate the door strike has been activated. If an incorrect relay activation code is entered, the unit will
disconnect. A simulated fast busy signal will also be returned to the entry phone if the telephone line has become
disconnected. A tenant may let themselves in by taking the entrance phone off-hook and entering a #followed by the
keyless entry code.
Note: To avoid busy signals, call waiting is recommended on each tenants phone line.
Operation
A six digit number may be used to access the programming mode. The security code has been factory set to
845464 (V-I-K-I-N-G). It is recommended that you change the security code to a personal 6 digit number as follows:
1. Access programming as shown in section A.
2. Enter your new security code followed by ##5.
3. Do NOT enter any Touch Tones for at least 20 seconds to exit programming.
D. Security Code
F. Built in Maximum Call Time and Toll Restriction
The maximum call time for the K-1900-3 is 2 minutes and cannot be changed. If the call exceeds 2 minutes, both
phones will be disconnected followed by three beeps indicating the termination of the call. This limits unnecessary
and lengthy conversations. The K-1900-3 will also disconnect on any Touch Tone or pulse dialing generated by the
entry phone after speed dialing has been completed.
Note: The security code must be six digits in length and can NOT contain a Qor #. If you have forgotten your
security code, see section A. “Local Programming Without the Security Code.”

The relay may be activated with a single digit, but must be programmed with a “0” + the digit (see section C, example 3).
When a single digit relay activation code is programmed (0-9), the activation Touch Tone must be held for a minimum of 150 ms.

Notes: Each pause uses a single speed dial digit. To clear a memory location, enter only the location (no digits). A valid
programming entry will be indicated by a double beep. An invalid entry will be indicated with three beeps.
These examples would be entered after accessing programming as shown in section A.
E. Keyless Entry Code
The K-1900-3 can be programmed to perform keyless entry. When a 4 - 6 digit keyless entry code is programmed,
a person may activate the door strike from the entry phone by dialing a “#” followed by the keyless entry code.
