Preparing to install the KT-400 Ethernet Four-Door Controller
Required to install KT-400 Ethernet Four-Door Controller
Physical Installation
Check for ideal indoor location
Stay away from electrical or communication devices
Earth Grounding
AWG#18 grounding wire to EGND
Door Locking Devices
Connect the door locked device to + and LK1-, (+ and LK2-), (+ and LK3-), or (+ and LK4-)
When jumper JP4 on INT (internal), the maximum current draw is 1 Amp at 12 to 13.75 VDC, or
When jumper JP4 on EXT (external), the maximum current draw is 3 Amps at 12 to 28 VDC
Check for local “magnetic lock” regulations
Hooking Up Inputs
Connect devices to inputs 1 to 16
Resistors for all inputs 5.6K ohm (if necessary)
Connect readers and keypads
Auxiliary Outputs
Connect auxiliary outputs to readers and local warning devices
Tamper Protection
Install tamper switch on cabinet
Connecting the KT-400 Ethernet Four-Door Controller
Connecting the VC-485 or the USB-485 to the RS-485 Bus
