Callout
Description
A
Relay 1: 30 VDC/VAC, 3 Amps, Form C, 0.6 power factor.
B
Relay 2: 30 VDC/VAC, 3 Amps, Form C, 0.6 power factor.
Connecting auxiliary outputs
•
To provide visual and audio signals of access operations, connect auxiliary outputs to card
readers and to local warning devices.
Note:
Auxiliary outputs activate according to input conditions, events, and local
alarms. LEDs provide visual feedback for access operations. Audible warning devices,
such as the T-REX or reader buzzer, signal door alarms.
Connecting the controller
CAUTION:
Do not connect several KT-1 controllers at a single point. Do not use splitters or
spider web (star) networks.
Note:
On the last controller of a loop, there is no end-of-line resistor to install on the RS-485
COM1 terminals.
1.
Connect the VC-485 or the USB-485 to the RS-485 Bus.
Note:
The use of a VC-485 was not evaluated by UL.
2.
Connect the RS-485 cable to (COM1) X+, X-.
Note:
The controllers are linked together through their RS-485 terminals. The
maximum communication loop length is 4,000 ft (1.2 km) using the appropriate
cabling. See Figure 21.
3.
Wire the RS-485 communication loop with an Ethernet Category 3 double twisted pair
(unshielded) network cable or better.
Note:
The RS-485 loop can operate from 1200 to 115200 Bauds under normal
conditions.
4.
Optional:
If you experience intermittent communication problems or erratic operation,
drop your network speed to a Baud rate of 9600 or 19200. If you vary the network speed, the
operating speed of the system does not change noticeably.
