Step 5. Door Locking Devices
_ _
_ _
_
Connect door locks to + and LK1- (+ and LK2-)
_ _
_ _
_
Maximum 250mA @ 12VDC per output
_ _
_ _
_
Check for local "magnetic lock" regulations
The LK1-, LK2- and + terminals are located on the bottom left of the
KT-300 controller's terminal strip. The locking device outputs are
controlled according to the end-user programmed parameters for allowing
access to or unlocking doors according to schedules and access levels.
These door locking device outputs can operate DC powered locking
devices such as electromechanical strikes and can be configured to operate
in fail-safe or fail-secure modes (normal or reverse action). The maximum
DC current for each lock output is 250mA.
Note: Use 1K ohm EOL (end-of-line resistor) between + and LK- if not
used. This resistor is already included within the controller's packaged box
(KT300-ACC).
WARNING: Controlled door locks may be governed by regulatory bodies
and should always be installed according to local regulations. In most
instances, there are strict limitations to installing fail-secure devices and
fail-safe locking devices such as magnetic locks or other similar locking
devices on doors used as emergency exits.
Step 6. Hooking Up Inputs
_ _
_ _
_
Connect devices to inputs 1 to 8
_ _
_ _
_
Resistors (included with KT-300) for all inputs 5.6K
ohm (if selected)
The KT-300 has an on-board capability of monitoring 8 input points (can
be expanded to 16 if KT-PC4108 module is used). Each input is supervised
with or without end-of-line resistors (5.6K ohm). The maximum distance
of one line is 600m (2,000 feet) with AWG#22 (Kantech part #CBL-R2).
Note: Inputs can be defined with: none or one EOLs (end-of-line) resistors
according to your EntraPass V3 or WinPass V2 software's settings.
Inputs 1-2 are automatically reserved for the first controlled door. The
contact is assigned input 1 and the associated request-to-exit detector as
input 2. Inputs 3 and 4 are automatically reserved for the second controlled
door. The contact is assigned input 3 and the associated request-to-exit
detector as input 4. There is no obligation to follow these rules but such
a standard convention makes it easier for servicing.

Step 7. Readers and Keypads
READER CONNECTION TERMINAL WARNING
Connecting the red wire lead (or power lead) of a 5VDC reader to the
12VDC terminal may damage the reader. See your reader installation
procedure for proper power connection. Up to 2 readers can be connected
to a KT-300. They can be installed on one door to control both entry and
exit or on two separate doors operating independently to control access
in one direction only.
The distance between the readers and the KT-300 controller varies by
reader type (please consult the reader manual for details). Auxiliary
outputs provide access operation visual and/or audible feedback at the
controlled door . Outputs "OUT DOOR 1 LED & BUZ" are used for the
first door and "OUT DOOR 2 LED & BUZ" are used for the second door.
The 12 VDC auxiliary power can also be used to power low current audible
devices usually located at the controlled door.
