Making a System Directional

Making a System Directional

If you need to know which direction a vehicle is traveling, or don’t want your audible device to sound when vehicles are exiting your property, Cartell has a relatively easy answer. Simply use two control units with two probes, each control unit having its own probe. One control unit will detect a vehicle and lock out the other control unit.

SYSTEM REQUIREMENTS

Two (2) CT-2B control units
Two (2) CT-6 sensor probes

INSTRUCTIONS – CONTROL UNITS AND SENSOR PROBES

1. Install two CT-2B control units in the house near each other. You will be running jumper cables between the two units as seen in Figure 2 below.

2. See Figures 1 & 2.
Figure 1 Overhead View of DrivewayFigure 2 Terminal Test Strip with ProbeInstall one probe (Probe A) by burying it beside a twelve foot wide driveway, at least 6 – 8 inches deep. Install the direct burial cable beside the drive and inside the home to the first CT-2B (A). Hook up the sensor probe as seen in Figure 2.

3. See Figures 1 & 2.
Install a second probe (Probe B) by burying it beside a twelve foot wide driveway, at least 6 – 8 inches deep and no less than ten feet from Probe A. Install the direct burial cable beside the drive and inside the home to the second CT-2B (B). Hook up the sensor probe as seen in Figure 2.

4. See Figure 2.
Run a jumper cable (22 gauge, indoor wire) from terminal 8 on the first CT-2B (A) to terminal 8 on the second CT-2B (B). Run a second jumper cable from terminal 9 on the first CT-2B (A) to terminal 9 on the second CT-2B (B).

INSTRUCTIONS – USING THE CT-A1

Use the CT-A1 If you wish to differentiate by sound which direction a vehicle is traveling. To use a sounder, connect a jumper wire from terminal #3 to #6 of the CT-2B you wish to annunciate. Follow the instructions that came with your annunciator, except you should move the wire normally connected to terminal #9 to terminal #7 for this application.
