Overview
The DSP-22S detector will add a new dimension of simplicity to your plug-in
detector requirements.
This series of Diablo's detectors are covered by
United States patent number US 7,132,959 “Non-Interfering Vehicle
Detection.” These detectors are virtually cross-talk free in most applications.
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 will be on steady to indicate the detector is operating
and powered. The red Detect LED will turn on when a vehicle is over the
loop detection area.
Detect Memory
Power interruptions of short duration are ignored. If power fails for
approximately 1 ½ seconds or less the detector “remembers” a vehicle.
Sensitivity and Reset Push Button
The Reset/Sens. button is used for two functions. A short press and
release of the button will reset the detector and the LED's will both flash
from 1 to 4 times, indicating the detector's sensitivity level. The detector is
shipped from the factory with the sensitivity set at level 3.
If a different sensitivity level is required:
Push and continue to hold the button until the LED's start flashing - release
the button immediately after the desired number of flashes. For example, if
the sensitivity is to be changed to level 2, push and hold the button until the
LED's flash twice then immediately release the button. The sensitivity level
can always be verified by a quick tap on the push button. This will reset the
detector and flash the two LED's indicating the present level.
Level 1 - Very Low
Level 2 - Low
Level 3 - Normal (Factory setting)
Level 4 - High
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.
