Diablo Controls DSP-14 Install Instructions

Overview
To ensure a reliable installation, a test should be done on site to determine a sensor installation location that will provide
the desired detection area without picking up the gate. This is done easily by temporarily securing the sensor on top of
the driving surface (preferably in the center of the driving surface) and connecting it the DSP-14M. The DSP-14M can be
temporarily placed anywhere where 8VDC to 48VDC power is available for powering the assembly. Once all wiring
connections are complete and a setting has been changed to force a reset without any vehicles around the gate and
sensor, the sensor location can be tested.
Testing consists of cycling the gate several times to ensure that the gate is not detected by the sensor. If the gate is
detected, the sensor can be positioned further away from the gate or, if the sensor cannot be moved further away due to
other obstructions, the sensitivity can be turned down. Now, a vehicle should be driven toward the sensor to observe
where vehicle detection occurs and where it ends to verify your desired detection area. Be aware that larger vehicles will
be detected further away than smaller vehicles. There is typically a two foot to three foot difference between a large SUV
and a small car with the sensor being more sensitive to the SUV. Be sure to test a vehicle as far off to the side as possible
to ensure vehicles not centered in the driving surface will be reliably detected. If the sensitivity is turned up to get the
desired detection area, be sure to go back and check if the gate is still not detected.
Once a good sensor location has been identified, mark the location and you are now ready to perform the final install
steps. The sensor can be mounted in any orientation and the sensor and wire can be direct buried. For brevity and clarity,
this document only describes a vertical installation with a saw cut for the lead-in cable and a trenched in horizontal
installation using conduit. Many other installation methods are possible.
For the vertical installation, core drill a 1" or larger hole at the marked location to a depth of at least 4" (6" is
recommended). NOTE: Unstable operation may occur if the sensor is not at least 4" down from the top of the roadway

DSP-14 Install Instructions
The sensor must be installed in a manner
that does not allow it to move. It must be
at least 4" below the driving surface.
