Audio cable
The two-way audio cable connects to terminal positions 9 and 10 of the lower barrier strip on the KTR-11 PC
card, and terminates at the control site (KTR304A or 304RA). See
on page 11 and
page 12. The cable’s shield should be continuous throughout its length and should remain unattached at all
points except at the control site.
Door control cables
The KTR-11 PC card contains two relays that provide dry contacts (1 A at 24 V) for door control. See
on page 14 for connection details.
