WARNING - PLEASE READ CAREFULLY
Note to Installers
This warning contains vital information. As the only individual in contact with system users, it is your responsibility to bring each item in this warn-
ing to the attention of the users of this system.
System Failures
This system has been carefully designed to be as effective as possible. There are circumstances, however, involving fire, burglary, or other types
of emergencies where it may not provide protection. Any access control system of any type may be compromised deliberately or may fail to oper-
ate as expected for a variety of reasons. Some but not all of these reasons may be:
•Inadequate Installation
An access control system must be installed properly in order to provide adequate protection. Every installation should be evaluated by a
security professional to ensure that all access points and areas are covered. Locks and latches on windows and doors must be secure and
operate as intended. Windows, doors, walls, ceilings and other building materials must be of sufficient strength and construction to provide
the level of protection expected. A reevaluation must be done during and after any construction activity.
•Criminal Knowledge
This system contains security features which were known to be effective at the time of manufacture. It is possible for persons with criminal
intent to develop techniques which reduce the effectiveness of these features. It is important that an access control system be reviewed peri-
odically to ensure that its features remain effective and that it be updated or replaced if it is found that it does not provide the protection
expected.
•Access by Intruders
Intruders may enter through an unprotected access point, circumvent a sensing device, evade detection by moving through an area of insuf-
ficient coverage, disconnect a warning device, or interfere with or prevent the proper operation of the system.
•Power Failure
Control units, readers, exit detectors and many other security devices require an adequate power supply for proper operation. If a device
operates from batteries, it is possible for the batteries to fail. Even if the batteries have not failed, they must be charged, in good condition

v
and installed correctly. If a device operates only by AC power, any interruption, however brief, will render that device inoperative while it does
not have power. Power interruptions of any length are often accompanied by voltage fluctuations which may damage electronic equipment
such as an access control system. After a power interruption has occurred, immediately conduct a complete system test to ensure that the
system operates as intended.
•Motion Detectors - Request to Exit
Motion detectors can only detect motion within the designated areas as shown in their respective installation instructions. Motion detectors
do not provide volumetric area protection. They have multiple beams of detection and motion can only be detected in unobstructed areas
covered by these beams. They cannot detect motion which occurs behind walls, ceilings, floor, closed doors, glass partitions, glass doors or
windows. Any type of tampering whether intentional or unintentional such as masking, painting, or spraying of any material on the lenses,
mirrors, windows or any other part of the detection system will impair its proper operation. Passive infrared motion detectors operate by
sensing changes in temperature. However their effectiveness can be reduced when the ambient temperature rises near or above body tem-
perature or if there are intentional or unintentional sources of heat in or near the detection area. Some of these heat sources could be heat-
ers, radiators, stoves, barbeques, fireplaces, sunlight, steam vents, lighting and so on.
•Component Failure
Although every effort has been made to make this system as reliable as possible, the system may fail to function as intended due to the fail-
ure of a component.
•Inadequate Testing
Most problems that would prevent a system from operating as intended can be found by regular testing and maintenance. The complete sys-
tem should be tested weekly and immediately after a break-in, an attempted break-in, a fire, a storm, an earthquake, an accident, or any kind
of construction activity inside or outside the premises. The testing should include all sensing devices, keypads, consoles, alarm indicating
devices and any other operational devices that are part of the system.

KT-300 Door Controller Installation Manual
Installing the KT-300
Physical Installation
Check for ideal indoor location.
Stay away from electrical or communication devices.
The KT-300 Controller cabinet has been designed to be mounted on a wall without any additional enclosures. The cabinet is
large enough to accommodate the battery backup supply and the necessary wiring connections for most applications. EMT
(Electrical Metallic Tubing) conduit knockouts are provided in 2.2 cm (7/8”) on all sides of the cabinet.
The cabinet should be mounted indoors, in a secure location providing normal temperature and humidity, leaving 23 cm (8”)
clear space around all sides and a minimum of 33 cm (13”) clear space in front of the cabinet. The location should be easily
accessible for servicing the equipment and it is recommended that controllers be located close to the controlled doors.
Controllers must be located at a minimum distance of 2 m (6 feet) from any high voltage equipment or wiring and from electrical
equipment susceptible of generating electrical interference, at a minimum distance of 1 m (3 feet) from telephone equipment or
lines, and at a minimum of 8 m (25 feet) from any transmitting equipment.
Physical access, using keys, on controlled doors must be provided so that the KT-300 can easily be accessed for servicing in
case of malfunction.
Earth Grounding
AWG#18 grounding wire to EGND.
The KT-300 uses high performance communication, proper grounding must be provided to ensure proper operation.
Make an earth ground connection to the cabinet of the KT-300 as per the requirements of your local electrical code. Wire the E-
GND terminal on the KT-300 printed circuit board directly to that connection point.
Door Locking Devices
Connect door locks to + and LK1- (+ and L2-)
Maximum 250mA @ 12 VDC per output
Check for local “magnetic lock” regulations
LK1-, LK2- and + terminals are located on the bottom left to the KT-300
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 fail-safe or fail-
secure (normal or reverse action). Maximum DC current for each lock
output is 250 mA.
NOTE: Use 1K ohm EOL (End-Of-Line resistor) between + and LK- if not
used. This resistor is already included within the controller
packaged box (KT-300ACC).
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.
This equipment is designed to be used in an environment that meets a maximum pollution degree of 2
and over voltages category II - NON HAZARDOUS LOCATIONS, indoor only. The equipment is FIXED
and PERMANENTLY CONNECTED. It must be installed in a metal cabinet by service persons only.
Service person is defined as: Persons having the appropriate technical training and experience
necessary to be aware of hazards to which they are exposed in performing a task and of measures to
minimize the risks to that person or other persons.

KT-300 Door Controller Installation Manual
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 (expandable 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.
NOTE: Inputs can be defined with: none or
one EOL (End-Of-Line) resistor
according to your EntraPass software
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 this standard convention
facilitates servicing.
Readers and Keypads
READER CONNECTION TERMINAL WARNING
Connection the red wire lead (or power lead) of a 5 VDC reader
to the 12 VDC 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 one-way
access.
The distance between the readers and the KT-300 controller
varies by reader type (please consult the installation manual for
details). Auxiliary outputs provide visual and/or audible access
operation 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.
Relay Controlled Outputs
Connect controlled outputs to low voltage devices (25
mA max).
Add external relays for high voltage devices (optional
- Kantech # KT-RM1).
The KT-300 provides two controlled outputs - RL1 & RL2 (open
collector to ground-current limited to 25 mA). Use a KT-RM1 (optional) to switch larger currents or voltages or to supply a dry
contact.
When activated, relay 1 and 2 (RL1 and RL2 LED) outputs provide visual feedback of their active status, as shown in Figure X.
Can be expanded up to 16 controlled outputs when using a KT-PC4216 module. This module allows a maximum of 16 outputs
and a maximum of up to 50 mA per output. Since the KT-300 only supports 500 mA, a power supply module can be used to
provide an additional 1 A to the Combus.
NOTE: If you are using a KT-PC4204 in “repower” mode and other KT-PC4216 modules that are assigned as relays 1-16 also
connected to the same loop, do not use relay 1 of those modules or relay 1 of the KT-300 Door Controller (see the
Combus Repower section for more information).

DN1315-1007 9
KT-300 Door Controller Installation Manual
Auxiliary Outputs
Connect auxiliary outputs to readers and local warning devices.
Auxiliary outputs are used for visual and audible signals. They can be activated according to schedules, input conditions or
events and local alarms. Auxiliary outputs “OUT DOOR 1 & 2 LED” provide visual feedback of access operation, and auxiliary
outputs “OUT DOOR 1 & 2 BUZ” can activate audible warning devices, such as T-REX, to signal door alarms.
Tamper Protection
Install tamper switch on cabinet (Kantech #KT-TAMP).
A tamper switch must be installed on the unit to detect unauthorized cabinet opening.
The normally closed tamper switch is connected to an input (choose an unused input (5 to 8) as tamper input or any other
unused inputs on the KT-PC4108 module (if used)).
NOTE: The tamper switch is required for a UL listed installation.
Connecting the KT-300
Connecting to the RS-485 Bus
Connect RS-485 cable to X1+, X1- and GND.
Controllers are linked together through their RS-485 connectors. The maximum communication loop length is 1.2 kilometers
(4,000 feet) using appropriate cabling. Connecting several KT-300 controllers at a single point is not acceptable nor are splitters
or “spider web networks.”
The RS-485 communication loop should be wired with Ethernet Category 3 double twisted pair network cable (see cable
specifications Belden 1227A, or equivalent). The RS-485 loop can operate from 1,200 to 115,200 bauds under normal
conditions.
Intermittent communication problems or erratic operation may require network speed drops to 9,600 or 19,200 Bauds. Varying
the network speed does not perceptibly change the operation speed of the system. Usually, most installations should be set to
19,200 Bauds.
NOTE: To learn more about USB-485 wiring, please refer to the USB-485 Installation Sheet, DN1482.

DN1315-1007 10
KT-300 Door Controller Installation Manual
Connecting the Master Controller to the Host
PC
Connect flat cable from KT-300 to the PC.
From 0 to 30m (0 to 100 feet):
If the local master controller is located less than 30m
(100 feet) from the host computer, use the on-board RS-
232 RJ12 jack and the supplied flat cable.
NOTE: If you plan to locate the host PC more than 30m
(100 feet) away from the controller, be sure to
use a VC-485 interface. Otherwise, reduce the
communication speed to a minimum to avoid
data loss.
From 30m to 1.2 km (100 to 4,000 feet)
If the master controller is located more than 60m (200
feet), an optional VC-485 multi-function communication
interface must be used. It can also be used when
running a communication cable in areas unusually high
in electrical noise.
NOTE: The host computer is used to program the KT-
300 Controllers.
Over Corporate Network (LAN)
If the master controller is used in a LAN-enabled corporate setting, use TCP/IP-to-RS-232
converter (such as the Kantech IP Link or the Lantronix UDS-1100 communication
interface) to connect the controller to the corporate network. This method uses existing
wiring for data exchange between EntraPass and the controllers. The diagram on the left
shows how to connect a DB-9 to RJ-12 flat cable between the master controller and the
converter. Consult Application Note DN1506 to learn how to set up the communication
interface.
For remote sites
If the master controller is used in remote areas,
modems must be used to send and receive
access control data over telephone lines. For this
application Kantech supports US Robotics 56K
external Sportster modems at both ends of the
communication line. As shown on the right, a
modem connects to the master controller only
using a DB25 to RJ-12 flat cable. For dial-up
communication settings via software, refer to
your communication settings.

KT-300 Door Controller Installation Manual
Powering the KT-300
Install 120 V / 16VAC, 40 VA, class 2 transformer (North Am.).
Connect 230 V / 16VAC, 100 VA, fused transformer (Eur.)
Place battery in cabinet.
Power the KT-300 controller.
The KT-300 Controller must be powered by a 16VAC/40VA class 2 wire-in or plug-in
transformer (applicable to the North American model). The KT-300 European
controller must be powered by a 16VAC/100VA fused transformer.
After you have completed all the necessary steps, you may power the KT-300
Controller. Connect AC power as well as the battery. Once powered, check the VITAL
LED status indicator to determine the status of communication and other vital
parameters. Consult the troubleshooting section for VITAL LED behavior
identification.
If the AC supply is removed, the 12 Volt 7 A/h led-type backup battery will support
normal operation for up to 12 hours if fully charged. Internal battery verification will
cutoff battery power if the battery voltage level falls below 9.5 Volts.
NOTE: The KT-300 Controller will not start on battery alone.
NOTE: Power should only be applied to the unit when all connections are completed
and tested.
Installing Combus Modules
Introduction to Combus Modules
The Combus terminals on the KT-300 Controller are used to connect expansion modules to add inputs, outputs, relays and LCD
time and date display. The four Combus terminals of the main panel must be connected to the four Combus terminals or wires
of all modules.
Four expansion modules can be connected to KT-300’s Combus (more specifications on each of these modules can be found
later on in this document.):
• KT-PC4108 - 8-Zone input expansion module
• KT-PC4204 - 4-Relay/Power supply expansion module
• KT-PC4216 - 16-Zone output expansion module
• KT3-LCD - Kantech LCD keypad module
Combus Specifications
The Combus provides 500 mA at 12 Volts (13.85 VDC). The recommended cable is
#22 AWG. Each loop (module to KT-300) cannot exceed 300 m (1,000 feet) and the
total maximum cable length of all connected loops cannot exceed 1,200 m (4,000
feet).
For example:
• Only four wireruns at 1,000 feet from the KT-300.
• Only eight wireruns at 500 feet from the KT-300.
• Only ten wireruns at 400 feet from the KT-300
Shielded wire should only be used in areas with excessive RF noise of
electromagnetic interference. Modules can be straight run, connected in a daisy
chain or T-tapped anywhere on the Combus.
Keep in mind that the new modules must be defined in the EntraPass system when
they are added to the Combus. Refer to the Controller Definition section in the EntraPass Reference Manual to learn how to
assign modules to your system.

DN1315-1007 12
KT-300 Door Controller Installation Manual
Combus Repower (If Required)
Depending on how many modules are connected to the Combus
and how far they are from the KT-300 controller, you may need to
“repower” the controller’s Combus.
The Combus needs to be “repowered” if the voltage drops below
12.5 Volts between black and red wires of the last module of each
loop (the modules will still operate but there will be no
communication between the modules and the controller and a
“Combus module defect” event will be generated from the
controller). This voltage drops if modules are drawing too much
current (500mA maximum for the Combus of each KT-300).
Verify this voltage with a multi meter, and determine if you need to
install a KT-PC4204 in “repower” mode. Using this configuration, you
will be provided with an additional 1 amp of current on the
controller’s Combus. The KT-PC4204 is generally installed at the
beginning of the loop.
When using the KT-PC4204 in “repower” mode, the first relay of the
module will be reserved for the “repower function”. You will have to
assign an “all valid” schedule to the first relay so it is “always
activated” (refer to the Controller definition section of your EntraPass
User Reference Manual for the exact procedure.)
If you are using a KT-PC4204 in “repower” mode and other KT-
PC4204 modules that are assigned as relays 1-4 or KT-PC4216
modules that are assigned as relays 1-16 are also connected to the
same loop, do not use relay 1 of those modules or relay 1 of the KT-
300 door controller. Please also note that all KT-PC4204 modules
that are used for Combus repower should be assigned as relays 1-4.
NOTE: Jumper 1 “J1” on the KT-PC4204 must be moved to the
Combus relay position.
NOTE: Do not use any power supply other than the KT-PC4204 to repower the Combus. In the event of a power surge or
transient, a module may lock up and cease to communicate with the controller. If the KT-300 loses communication with
the module, it will initiate a module reset and will power down the Combus for five seconds in an attempt to reset the
problem module. After five seconds, the controller will reapply power to the Combus and the problem module should
begin to operate as intended.

KT-PC4108 Input Module
KT-PC4108 Introduction
The KT-PC4108 module is a zone input module that adds up to 8 fully
programmable zones to the KT-300 Controller.
KT-PC4108 Specifications
• Connects to the controller via 4-wire Combus
• Current draw: 30 mA (from Combus)
• Supports single end-of-line and no end-of-line (5600 ohm
resistors) zone loops
• AUX+ output: 12 VDC, 250 mA max. (drawn from Combus)
• Tamper contact input
• UL listed
Unpacking the KT-PC4108 Module
The KT-PC4108 package includes the following parts/items:
• One KT-PC4108 circuit board - 9.2 cm x 3.3 cm (35/8” x 11/4”)
• 16 end-of-line resistors (5600 ohms)
• Three (3) plastic standoffs with adhesive
• One (1) installation instructions sheet
Mounting the KT-PC4108 Module
The KT-PC4108 module should be located inside a compatible cabinet (Kantech part no. KT-4105 CAB), mounted in a dry,
secure location. Preferably, it should be placed at a convenient distance from the connected devices.
Perform the following steps to mount the unit:
1. Press the three (3) plastic standoffs through the mounting holes on either side of the cabinet.
2. Secure the cabinet to the wall in the desired location. Use appropriate wall anchors when securing the cabinet
to drywall, plaster, concrete, brick or any other surfaces.
3. Press the circuit board into the three (3) plastic standoffs to secure the unit to the cabinet.
4. Remove the protective film from the plastic standoffs and attach the circuit board to the cabinet.
NOTE: Wiring may take place once the unit is mounted.
Installation and Wiring
Before wiring the unit, ensure that all power sources (AC transformer and battery) are disconnected from the controller. Perform
the following steps to complete wiring:
1. Connect the four Combus wires to the KT-PC4108. Connect the Red, Black, Yellow and Green Combus wires
to the RED, BLK, YEL and GRN terminals, respectively.
2. Complete all zone wiring to the zone input terminals (Z1-Z8).
3. Connect the external tamper switch, if used.
NOTE: Consult the wiring diagram above for further information.
Applying Power
After wiring is completed, apply power to the controller. Connect the battery leads to the battery, then connect the AC
transformer.
NOTE: Do not connect the power until all wiring is completed.
Assigning the Module
Once all wiring is completed, the module must be assigned to the system. To assign the module, perform the following steps:
1. Establish communication between EntraPass and the controller.
2. Remove the tamper switch wire (or only the wire if tamper switch is not used). If there is no connection to the
TAM input, use the Tamper Switch button to generate an event.
3. An event will be displayed on the EntraPass workstation Desktop Message screen, indicating the module’s
serial number, type and the controller to which it is connected.
4. From the software, select the functionality of the module and enter the serial number in the appropriate field
(see your software reference manual under controller definition -- Assigning modules for more details).
NOTE: Do not forget to reconnect the tamper switch (or the wire, if there is no tamper switch).
