KT-300 Door Controller Installation Manual
Wiring the
KT3-LCD
Before beginning to wire the unit, ensure that all power (AC transformer and battery) is
disconnected from the control panel.
To complete keypad wiring, connect the four Combus wires (Red, Black, Yellow and
Green) to keypad terminals R,B,Y and G.
Applying Power
1. Once all wiring is completed, turn the controller on.
2. Connect the battery leads to the battery.
3. Connect the AC transformer.
NOTE:
Do not connect the power until all wiring is completed.
Assigning the KT3-LCD Keypad
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. Press the pound key (#) on each keypad. A serial number should be displayed in the EntraPass message
desktop. Look for the type of module and the controller to which it is connected.
3. From the EntraPass controller definition window, select the functionality of the KT3-LCD and enter the serial
number in the appropriate field (refer to
Chapter 4, Defining Devices
of the
EntraPass Reference Manual
for
more details).
Troubleshooting Communication Problems
Default Initialization
The KT-300 default initialization is done at Kantech. The following steps should only be followed if:
a You are using a KT-300 from another site and there is no communication;
b The KT-300 was communicating via the RS-232 port and you installed a VC-485 to
communicate via the RS-485 port;
c You were using the KT-300 at a local site and now want to configure it for remote
operation.
How to Use the Default Initialization (Hard Reset)
1. Disconnect both transformer and battery.
2. Remove all connection to DOOR1 and RL1 terminals.
3. Place a jumper between the DOOR1 and RL1 terminals.
4. Apply AC power to the transformer. The VITAL LED should flash 4 times. This means that
the controller is in the initialization mode.
5. Remove jumper.
6. Reconnect the battery.
VITAL LED status indications
Communication status and other vital controller parameters can be obtained from VITAL LED pulsations.
This information is particularly useful when connecting the controller to the rest of the access control
system. Consult the KT-300 Controller Wiring Diagram on page 20 to locate the VITAL LED. The following
table lists all conditions along with a brief description
