When more than 1 probe is used, connect the red and black wires in series. Connect
the silver wires in parallel. The red wire from one cable is soldered to a black wire from
another cable. The remaining red wire & black wire are attached to the Drive-Alert
terminals. All silver wires are attached to the Drive-Alert.
Keep the probe, cable, and control panel at least 8 feet away from heavy power lines,
power panels, motors, arcing or sparking machinery, and radio transmitters. In some
cases, moving the panel and/or cable a few feet can solve interference problems.
FIGURE 1 illustrates the contacts on the bottom of the DA-500 Control Panel, with the
sensor correctly attached.
FIGURE 1
The sensing probe is a 1” x 12”
cylinder containing a sealed
sensor. Be cautious when
handling the sensor and
particularly careful to not nick
the cable attached to it.
Bury the probe at least 6” deep.
A typical installation is the probe
6 inches deep parallel to drive,
which will allow the probe to
“sense” 12’ across the driveway.
The ideal installation allows you
to extend your detection
range by installing the sensor
under the center of drive.
