DKS 1601 - Two Way Lane Application

2.4.4 TWO-WAY LANE APPLICATION
• Plug a 9406 loop detector into the UP loop port on the 1601 circuit board and connect the
EXIT loop to terminals TB-1.
• Use a 9405 loop detector plugged into the DOWN port on the 1601 circuit board. Connect
the DOWN loops, wired in series, to terminals TB-1 and the ARMING loop to terminals TB-2.
• If the optional arming loop is not used, use a 9406 detector plugged into the DOWN port on
the 1601 circuit board and connect the DOWN loops, wired in series, to terminals TB-1 on
this detector.
• The timer (SW-1, switch 7) should be OFF. The arm will rotate down after the vehicle clears
the down loops.
• SW-1, switch 4 must be ON.
• Spacing of the loops is critical when using this configuration. Be sure that the loops are
spaced as shown in the diagram.
