Q. DIP Switch Programming / Speaker and Microphone Adjustments
Two POTs are provided to increase or decrease speaker volume and microphone sensitivity. In certain noisy
locations the microphone sensitivity may need to be decreased as shown below. Caution: Setting the microphone
gain too high may cause distorted audio, prevent the distant party from breaking over and inhibit second number
redialing.

Note: On some phone lines, busy and ring back tones may be very soft. In these installations, set DIP switches
2 and 3 to OFF.
When a visitor is at the K-1270, they just need to find the name of the tenant they want to visit on the
directory and press the associated button. The K-1270 will then seize the phone line and speed dial
the number programmed for that name. When the tenant answers the call, they can let the visitor in by
entering the Door Strike Code on their telephone keypad. The tenant can converse with the visitor for
up to 10 seconds after the Door Strike Code is dialed (to verify the visitor has been granted entry). The
K-1270 is able to determine if the door strike command is coming from the apartment or the caller, to
prevent entry using a hand held touch tone dialer. If the tenant chooses not to let the visitor in, they can
simply hang up the phone. The K-1270 will drop the line when busy, reorder, CPC signals are detected,
when programmable maximum call time out, silence time out, maximum ring timers expire or 10
seconds after a door strike activation. Only the buttons that have a programmed phone number are
active (except "#" when used for keyless entry). After a button is pressed, and the call is initiated, it can
be canceled by momentarily pressing any button on the panel.
If a second number is programmed for the selected tenant, and there is no answer or busy after dialing
the first number, the K-1270 will hang up, pause, seize the line, and then dial this second number. In
this manner the call can be routed to a cell phone if the tenant is not at home. The tenant can still let
the visitor in using the Door Strike Code.
It is also possible to talk to a visitor before they press a directory button, and to let them in if Tenant
Initiated Entry has been enabled. Make sure DIP switch 1 is on (Auto Answer, see section Q), and
then call the number of the K-1270. The unit will answer and send a single or double beep. After a
single beep, if Tenant Initiated Entry is not enabled the tenant can converse with the visitor but is not
able to use the doorstrike code to let them in. If Tenant Initiated Entry is enabled, the tenant can enter
the access code following the single beep, hear two acknowledgement beeps, and then either let the
visitor in using the doorstrike code or hang up to terminate the call. A double beep after the unit answers
indicates both that Tenant Initiated Entry is enabled and that the access code is disabled, so the user
can let the visitor in using the doorstrike code without having to enter the access code, or terminate the
call by hanging up.
To use the keyless entry feature, momentarily press or press and hold the "#" key on the K-1270 keypad.
When momentarily pressed, 1 beep will be heard and if held for 2 seconds (or longer), 2 beeps will be
heard. In either case, the K-1270 is then ready to accept the keyless code. Continue by entering one
of the previously programmed keyless codes. The K-1270 will pause a few seconds to make sure there
are no more keypad entries, and then actuates the Door Strike relay if valid. If an incorrect code is
entered, the K-1270 will beep 3 times and the user has to start over and enter a correct code.
If a Postal Lock is used, a momentary closure of the postal lock switch will energize the door strike for
the programmed Door Strike Time.
Turn POTS clockwise to increase
(as viewed from the back of the board).
