B. Changing the Directory
To install a directory, remove the four screws that
mount the directory lens to the front of the K-1200
using the included Allen wrench. Insert a paper direc-
tory behind the lens and secure the two back onto the
front panel being careful to align the names with the
front panel graphics. For your convenience, the back
of this document has pre-printed directory forms.
C. Wiring
The K-1200 can be powered from any source supplying 12 to 24
volts, AC or DC. A 12 volt DC adapter is supplied with the product.
When using the included adapter, the plug on the adapter cord will
have to be removed. The power connections to the K-1200 (black
wires) are not polarity sensitive.
There are also 8 more wires connected to the K-1200 controller
board. Two wires are for the incoming phone line, three are from the
high current door strike relay and the last three are from the camera
relay. Gel filled butt connectors are provided for easier connection to
building wiring. The table at the right describes each wire's function.

Important: To operate the K-1200 during a power failure, a UPS should be installed.
A. Connecting a Doorstrike to the K-1200 Internal Relay
The K-1200 provides a dry contact output that can be used for operation of a door strike. To use this feature, the Door
Strike Code and Door Strike Time must be set in programming. In this mode, when the Door Strike Code is detected,
the K-1200 will energize the relay for the period of time selected in the Door Strike Time (see Programming section E
and F).
If a Postal Lock is required, connect the normally open contacts of the lock to the two white wires coming from the two
pin connector on the lower portion of the control board. When the postal lock is momentarily actuated, the door strike
will energize for the programmed Door Strike Time.
* Note: To prevent unwanted radio interference, route the connecting wires through the included ferrite core.
** Note: The gel-filled (water-tight) butt connectors are designed for insulation displacement on 19-26 gauge wire with a maximum
insulation of 0.082 inches. Cut off stripped ends prior to terminating.
