Automatic Exit Delay with DriveGuard Ultra™

Automatic Exit Delay with DriveGuard Ultra™

The exit delay feature on the CF-2C, when combined with the CT-A1 annunciator, allows a person to drive a vehicle by the sensor probe without being detected. You simply push the “Exit” button on the CT-A1 annunciator faceplate on your way out of the house.

Now when your vehicle passes the hidden probe, the lights and sounders connected to your system will not activate. This is especially helpful late at night when someone wants to leave without disturbing the rest of the family.

These instructions explain a way to enjoy the exit delay feature automatically, without having to remember to push a button before leaving home.


1. Your original CF-2C system (DriveGuard Ultra™)
2. A separate CT-2B control unit (DriveGuard Basic™)
3. A second sensor probe connected to the CT-2B (DriveGuard Basic™)


1. Install a CT-2B control unit in the house near the original CF-2C. You will be running jumper cables between the two units, using the CT-2B to activate the exit delay on the CF-2C.

2. See Figure 1.
 Exit Delay Install a second sensor probe (Probe B) at least fifty feet closer to the house from your original probe. (Probe A). Bury it beside a twelve foot wide driveway, at least 6 – 8 inches deep. Trench the direct burial cable up the drive and inside the home to where you have installed the CT-2B. Connect the sensor probe as seen in Figure 2.

3. See Figure 2.
Terminal Strips with ProbesRun a jumper cable (22 gauge, indoor wire) from terminal 6 on the CT-2B to terminal 15 on the CF-2C. Run a second jumper cable from terminal 7 on the CT-2B to terminal 9 on the CF-2C control unit.

4. On the CF-2C control unit, turn the exit delay potentiometer (“C”) to suit the driveway (refer to the CF-2C Manual). When you drive past Probe B, the original probe (Probe A) will be deactivated for 15 minutes. You can now drive by it without being detected.
