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.
Powering the KT-315
Place battery in cabinet.
Power the KT-315 controller.
The KT-315 Controller must be powered by a 16VAC/40VA class 2 wire-in or plug-in
transformer.
After you have completed all the necessary steps, you may power the KT-315
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 lead-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-315 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-315 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-315’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
