The KT‐300 constantly supervises battery condition and reports “Low battery / No battery condition” status to the system. It also supervises locking devices for short and open circuits to detect lock failures. KT‐300 controllers support Combus modules. The Combus is a 4‐conductor cable bus to which several expansion modules are connected in parallel to add inputs, outputs, relays and an LCD time and date display.
1 From the Site menu, click the Controller icon, then select the KT‐300 tab.
2 Enter the controller serial number in the Serial number field. Usually, the number is found on the controller label. The field is defined to accept only numeric characters, except for the first character. It may be an a or A. If a lower case character is entered, the system converts it to upper case.
3 Enter the Wait for second access card delay. The maximum time allowed is two minutes and seven seconds. If the value entered is greater than the maximum allowed, the system will use the existing value. This feature is useful when access to a place is controlled by two cards.
4 In the Keypad escape key drop down list, choose a keypad escape key if applicable. This feature is associated with PINs. When a user enters a wrong number, he/she may press the escape key and re‐enter the PIN, without incrementing the number of attempts. 5 In the EOL resistor (5.6K) drop‐down list, select the resistor type. By default, the Single resistor option is selected. If you hear a long buzz, verify the number of resistors installed on your system.
Configuring the KT‐300 Combus Modules
Five combus modules can be connected to a KT‐300: • KT‐PC4108 (8‐zone input expansion module). This module has a tamper contact input. • KT‐PC4116 (16‐zone input expansion module). This module has a tamper contact input. • KT‐PC4204 (4‐relay/power supply expansion module). It has a tamper contact input and also includes a built‐in 12VDC, 1A power supply for field devices.• KT‐PC4216 (16‐zone output expansion module). It can be used for elevator control, although additional hardware may be required.
• KT‐LCD3 (Kantech 32‐character liquid crystal display). The LCD is green (normal status), red (power failure) and yellow (trouble).
1 If a Combus module is installed to the KT‐300 controller, click the Combus module configuration button. Undefined Combus terminals are identified by red flags/bullets. Once a module has been defined, it is identified by a green flag.
2 To define a module, select one, then click the Define button (lower part of the window). The Enter Combus module serial number message box appears.
3 Enter the module’s serial number, then click OK.
NOTE: To obtain this number, you have to activate the Tamper switch or to press any key on the keyboard. The Combus serial number is displayed in the Desktop Message.
5 Check the options related to the module you want to configure (if these are displayed in the window). NOTE: Usage options of a module vary according to the selected Combus module. For example, installing the KT3‐LCD and checking the options Combus low power and Display date and time will allow the KT‐300 to report Combus low power conditions and to display the date and time. The following table summarizes the options associated with each module: 6 Check the Combus low power option so that the KT‐300 will report any Combus low power condition 7 Check Display date and time option so that LCD can display the date and time. 8 When you have finished configuring the Combus module, click the OK button to go back to the Status relay tab.
9 Associate a Local activation relay for Power failure, Combus failure and Combus low power (Multi‐site Gateway only). If you want to assign a specific relay, you may click the three‐dot button and select a specific relay or group of relays.
NOTE: To configure local activation relay, you must configure relays (Devices > Relays), and then select specific relays for local activation.
10 Under Priority call type, assign the call type option that best suits failure event reporting (Multi‐site Gateway only). To access the Priority call type feature, the site connection type must be set to Modem. NOTE: For details on defining controller options for KT‐300 controllers, see "Defining Controller Options" on page 78.
NOTE: For more information, see "Sites Configuration" on page 61.

EntraPass system. Power outputs are supervised and electronically protected against short‐circuits and surges. Locking devices are also supervised for short and open circuits. NOTE: For hardware information on the KT‐400 Ethernet Four‐Door Controller, please refer to the KT‐400 Ethernet Four‐Door Controller Installation Manual, DN1726. 1 From the Devices > Controller menu, click on the General tab and select the Reader type(s). 2 Select the Keypad type (if applicable).
3 Click on the KT‐400 tab. Enter the controller serial number in the Serial number field. The number is found on the controller label next to the reset button. The field is defined to accept only numeric characters, except for the first character. It may be an a or A. If a lower case character is entered, the system converts it to upper case.
4 Enter the Wait for second access card delay. The maximum time allowed is 4 minutes and 15 seconds. If the value entered is greater than the maximum allowed, the system will use the existing value. This feature is useful when access to a place is controlled by two cards.
5 In the Keypad escape key drop down list, choose a keypad escape key if applicable. This feature is associated with PINs. When a user enters a wrong number, he/she may press the escape key and re‐enter the PIN, without incrementing the number of attempts.
6 In the EOL Resistor (5.6 K) drop‐down list, select the resistor type. By default, the Single resistor option is selected. If you hear a long buzz from the installed reader/keypad, verify the number of resistors installed on your system.
