Features
Overview
Works on any in-ground inductive
loop from 20 to 2000 microhenries.
Designed to be cross talk free
between other loops
Automatically compensates for loop
and lead-In sizes
Switchless, self-adapting to most
common installations
Plug and play; Connect it up and
watch it work
Small profile, perfect for many
installations
Fail safe operation
Wide low-voltage operation
This series of Diablo Controls
detectors are covered by United
States Patent number US 7,132,959
“Non-Interfering Vehicle Detection.”
The DSP-11-LV is protected from
damage if plugged into a higher
voltage. No need to change a fuse
or reset a circuit breaker, simply
plug the detector into the proper
voltage and it works.
Separate Power/Fail and Detect
LEDs.
Industry standard 11-pin connector
in a small plastic case
Product Profile
DSP-11 Vehicle Detector
All this and a 5-Year Warranty Too!
Detector operates on any voltage from 10 to 30 volts AC or DC and draws about 35
milliamp of current with no vehicle on the loop. This micro-sized detector will
automatically adjust its sensitivity level when used on different sized loops. The detector
loop inductance should be between 20 and 2000 microhenries.
LED Indicators
The green Power LED blinks once per second to indicate the detector is operating and
powered. The red Detect LED will turn on when a vehicle is over the loop detection area.
Loop or Wire Failures
In the case of a loop circuit failure, the green LED flashes slowly (twice per second) for an
open loop circuit failure. The green LED will flash fast (10 times per second) to indicate a
shorted loop circuit.
Fail Safe vs Fail Secure
A fail safe detector will output “detect” when the loop circuit is failed. This is always useful
on a safety loop. On the free exit loop this will keep the gate open until the situation is
fixed. This is useful in applications where it is important to allow traffic flow to continue. A
fail secure detector will never output “detect” when the loop circuit is failed. This will keep
the gate closed. This is useful in high-security areas or installations where containment is
needed. The DSP-11 is a fail safe detector. Note: Never use a fail secure detector on a
safety loop.

Ordering Information
Standard part numbers are as follows: DSP-11-xxx
xxx = LV = Low voltage model 10 to 30 volts AC or DC
xxx = 117 = 117 volts AC
xxx = 230 = 230 volts AC
Pin 1 (black wire) - Power in (See model type)
Pin 2 (white wire) - Power in (See model type)
Pin 5 (yellow wire) - Output relay common
Pin 6 (blue wire) - Output relay N.O. - (closes for detect)
Pin 7 (gray twisted wire) - Loop input
Pin 8 (brown twisted wire) - Loop input
Pin 10 (pink wire*) - Output relay N.C. - (opens for detect)
*This wire is black (with white) on some harnesses.
