3. Introduction
The DSP-13M and DSP-13S make up the TRI-Axis Detection (TRIADTM) system. The TRIAD system is based on a
technology that measures very small changes in the earth’s magnetic field in all three axes. This means that the
TRIAD system works properly regardless of the orientation of the sensor. With sensor orientation no longer an
issue, the installer can install the sensor in whatever manner best suits the site. The TRIAD system can be installed
using a single saw cut. The sensor is potted in epoxy to provide durability and small enough that it can be placed
in a 1” cored hole. It can also be installed up to three feet below the driving surface. This allows the TRAID sensor
to be placed below pavers in a driveway or under asphalt or concrete in new construction.
The TRIAD system was specifically developed for access control systems that need reliable vehicle detection for
all weather conditions with a minimally invasive installation. The system is comprised of two parts, a master unit
(DSP-13M) and a sensor (DSP-13S). The advanced sensor’s small size and high sensitivity make it ideally suited to
vehicle detection applications.
The DSP-13 Master uses a 10-pin Molex connector for connections. This can be plugged into a Diablo Controls RK-
1R or RK-3R rack.
One of the distinguishing features of the TRIAD system is its ability to hold detection indefinitely, even through
power interruptions. Even if a vehicle arrives when the unit is without power, when power is restored the TRIAD
system will show detect if there is now a vehicle in the detection zone.

5. Features and Functions
Two Solid-State Outputs
The DSP-13M has two solid-state, open-drain, outputs. They are identified as Output A and Output B. These
two outputs are not isolated and are referenced to power common.
The functions of Output A and Output B are selected with the Pulse / Presence switch (DIP Switch 2). And are
summarized in the following table:

Presence Detection
NOTE: If using the supplied RK-1-R to plug the DSP-13 Master in to, Output B will not be available. Contact
Diablo Controls for the availability of other RK products that do support the use of Output B.
Presence Detection
The output will remain activated as long as a vehicle is sensed in the detection zone. This detection system always
operates in a permanent presence or infinite presence detection mode. The sensor technology used can
remember vehicles in the detection zone even if the power is interrupted for long periods of time. In fact, it can
determine if a vehicle arrived in the detection zone while power was removed and provide the correct presence
output on power restoration.
If a sensor failure is detected, this output will look at the Fail-safe / Fail-secure switch to determine what the state
of the output should be.
If the output is being used as a safety (also known as obstruction or reversing) input to a gate operator,
it must be in the presence detection mode and the failure mode to fail-safe.
Pulse On Entry Detection
The output will turn on for 250 milliseconds when the vehicle is first detected and will not output again until the
detection zone is no longer occupied. After the pulse is sent and the detection zone is still occupied, the detect
LED will display a “flicker” indication showing that the pulse has been sent and the zone is still occupied. This type
of output is often used for ticket issuance.
If a sensor failure is detected, this output will not provide any output (fail-secure operation).
Pulse On Exit Detection
The output will turn on for 250 milliseconds when a detection has occurred, and the detection zone is now vacant.
This type of detection is often used to trigger license plate cameras.
If a sensor failure is detected, this output will not provide any output (fail-secure operation).

Fail-Safe vs Fail-Secure
Fail-safe and fail-secure refer to what should happen to the output if the detection system knows that it is not
functioning correctly (cut lead-in, sensor failure, etc.). Fail-safe and fail-secure only apply to an output in the
presence mode of operation. Any pulse mode of operation is always fail-secure.
For most applications, fail-safe is the desired mode of operation as it will usually leave a gate open during a failure.
But for those applications where security is paramount, fail-secure is used to keep the gate from opening on a
failure.
Fail-Safe
When an output is in the presence mode of operation and a failure is detected, the output will stay activated
during the failure. In gate applications, this feature is used to automatically open the gate if the detection system
fails.
It should be noted that a power failure will always result in a fail-secure operation. Fail-safe operation is only
available when a valid input voltage is applied to the DSP-13 Master. Outputs configured for a pulse output will
always operate in the fail-secure mode.
Fail-Secure
When an output is in the presence mode of operation and a sensor failure is detected, the output will stay
deactivated during the failure. In gate applications, this feature is used to keep the gate closed if a sensor fails.
It should be noted that a power failure will always result in a fail-secure operation. Outputs configured for a pulse
output will always operate in the fail-secure mode.
If any output is being used as a safety (also known as obstruction or reversing) input to a gate operator,
the fail-safe mode of operation must be used.
Sensitivity
The DSP-13 has ten user selectable sensitivity levels. In most situations, the setting of 5 will work effectively. The
sensor has hysteresis between the detect and drop thresholds to ensure that the DSP-13 output does not chatter
during fringe detections.
Detection System Reset
When the reset switch is pressed, the DSP-13 Master will send a reset command to the connected sensor. If a
prior sensor fault was being displayed, it will be cleared.
Care should be taken to ensure that the DSP-13 is not reset while any vehicles or objects are in or near
the detection zone. These vehicles or objects may cause a permanent offset in the reference readings
for the sensor and may impact correct operations of the sensor.

Indicators
The DSP-13M is equipped with two LED indicators: Power (Green) and Detect (Red).
Power LED – The green power LED has several possible states:
OFF The voltage applied to the DSP-13 is less than the minimum display voltage of
approximately 3.3 volts. The DSP-13 should not be operated below 7 volts DC as
unpredictable operation will occur.
RESET IN FAIL-SAFE When the DSP-13 is reset (a reset occurs automatically at power up), the LED will
turn on for 500 milliseconds, off for 500 milliseconds, on for 500 milliseconds, off
for 500 milliseconds, and then resume its normal display.
RESET IN FAIL-SECURE When the DSP-13 is reset (a reset occurs automatically at power up), the LED will
turn on for 500 milliseconds, off for 500 milliseconds, then on for 50 milliseconds,
off for 50 milliseconds (10 times), and then resume its normal display.
MASTER FAILURE When the master unit detects a failure the LED will flash on once for 150
milliseconds every two seconds. This usually indicates that there is no sensor
attached or that the cable has been cut.
SENSOR FAILURE When a sensor unit has identified an internal fault and has sent this information
to the master unit the LED will flash on twice for 150 milliseconds every two
seconds. If cycling power does not correct the fault, the sensor must be replaced.
COMM FAILURE When a sensor is detected but cannot reliably communicate with the master unit
the LED will flash on three times for 150 milliseconds every two seconds. This
usually indicates a shorted cable, loose connections, or electrical interference.
PRIOR MASTER FAILURE The DSP-13 is equipped with the ability to remember prior master faults that have
occurred since the last power interruption or reset. The LED will flash off once
for 150 milliseconds once every two seconds (one flash) and then repeat the
sequence until power is cycled or the DSP-13 is reset.
PRIOR SENSOR FAILURE The DSP-13 is equipped with the ability to remember prior sensor faults that have
occurred since the last power interruption or reset. The LED will flash off twice
for 150 milliseconds once every two seconds (two flashes) and then repeat the
sequence until power is cycled or the DSP-13 is reset.
PRIOR COMM FAILURE The DSP-13 is equipped with the ability to remember prior communications faults
that have occurred since the last power interruption or reset. The LED will flash
off three times for 150 milliseconds once every two seconds (three flashes) and
then repeat the sequence until power is cycled or the DSP-13 is reset.
