The DriveGuard S.D.™ system is recommended for driveways under 75 feet. It is an optional dual-probe sensing device used in the place of the single probe sensing device normally used with the DriveGuard Basic, Integrator and Ultra systems.
The S.D. dual-probe sensor, like our other sensor, is buried beside and near the end of the driveway, hidden and vandal-proof. It only detects moving steel, eliminating false alarms caused by animals or blowing objects. It is distinctive from our other sensor probe because it can be as close as 10 to 15 feet to outside cross traffic at the end of the driveway, making it suitable for short driveways.
Because of its sensitivity, our normal sensing device (called CT-6 sensor probe) must be placed at least 35 feet back from residential traffic (going 35 MPH or less) and 50 feet back from highway traffic (above 35 MPH).
The S.D. sensing device is composed of two probes connected by direct burial cable, buried 2.5 feet apart (see graphic below). A vehicle is not detected until it enters the driveway.
Use the DriveGuard S.D.™ with either the DriveGuard Basic™, DriveGuard Integrator™ or DriveGuard Ultra™ when vehicle detection is desired on driveways less than 75 feet.

DriveGuard S.D.™ Components
Three components make up the DriveGuard S.D.™ system:
1. Either the CT-2B control unit or CF-2C control unit
2. SD-6 dual-probe sensor
• A. CT-2B control unit
The CT-2B control unit has a single timed output with simplified features. Field adjustments include relay time and sensor probe sensitivity.
It comes in a high quality, white metal enclosure and is usually installed in a closet, basement, garage, utility room, etc.
The CT-2B supports only one SD-6 sensor probe and twelve sounders.
• B. CF-2C control unit
The CF-2C control unit is a full-featured controller with dual timed output. It includes a 15 amp floodlight relay that can control up to 1800 watts of lights from a single circuit. Field adjustments include relay time, sensor probe sensitivity, floodlight time, re-trigger hold-off and more.
It comes in a high quality, white metal enclosure large enough to hold a 12 volt battery (optional) that will allow sounder(s) to operate during power outage. Battery charger built in. The CF-2C is usually installed in a closet, basement, garage, utility room, etc.
The CF-2C supports only one SD-6 sensor probe and twelve sounders.
• SD-6 sensor probe
Based on magnetometer technology, the SD-6 is a dual-probe sensor that detects movement in the earth’s magnetic field caused by moving steel. It will not detect animals, people or blowing objects. Wind and weather do not affect it. This makes it virtually false-alarm proof. It does not require power.
The SD-6 sensor probe is a dual-probe system buried 6-10 inches underground, near the end, beside, and parallel to, the driveway. Both probes are connected together by direct burial cable and should be buried 2.5 feet from each other. They cover a 12′ wide driveway from the side. Direct burial cable is attached, making conduit unnecessary. The cable is buried 3-6 inches underground, up to and into the house. It is connected to the control unit.
The SD-6 comes with a custom length of direct burial cable attached in the amount of 50′, 100′, 150′ or 200′. The cable is polyurethane coated, making repair-splicing in the field possible.
Sounder(s) connected to the control unit alert the home occupants when vehicles are detected. These are flush mounted in a single gang electric box. They are connected to the control unit with CAT-5 wire. Each home will determine how many sounders should be used for best effect.
Three sounders are available:
A. CT-A1 is an electronic membrane sounder that blends in with any decor. Volume may be adjusted and muted. Three buttons on faceplate interact with CF-2C to control lights and sensor probe. “ON” turns lights on from sounder; “RESET” turns lights off if they have not timed out; and “EXIT” turns sensor probe off so care can pass by and not trip the system (e.g. when someone is leaving early in the morning and does not want to awaken home occupants). If the CT-A1 sounder is used with the CT-2B, these three buttons remain nonfunctional.
B. CT-11 is an outdoor sounder with manual volume control. Includes metal face plate and gasket for weatherproof installation in single gang electric box.
C. AA-1 is a simplified sounder with a volume control knob. May be muted.
