DIABLO DSP-50, Plug-In Vehicle Detector
REPLACED BY DSP-55 ALL NEW ORDERS AND RMA'S WILL BE FILLED WITH THE DSP-55
DSP-50, Plug-In Vehicle Detector
The DSP-50 detector will add a new dimension of simplicity to your plug-in detector requirements as it can operate as a loop detector but with the flip of a switch it can operate our probe in pulse mode.
This detector operates on any voltage from 10 to 30 volts AC or DC.
It can be connected to a standard inductive loop or one of our new mini-loops. The Diablo Controls mini-Loop is a small “pipe shaped” device approximately 5” by 3/4” and is designed to be buried in the ground to detect vehicles.
The DSP-50 can be used as either a safety loop or free exit loop detector. With the flexibility to be either “fail safe” or “fail secure,” it is the most “user friendly” detector on the market today.
Only one model available: DSP-50
Works on any in-ground inductive loop from 20 to 2000 microhenries.
Can be connected to a standard inductive loop as well as the new mini-loops
Designed to be cross talk free between other loops
Automatically compensates for loop and lead-in sizes
Small profile, perfect for many installations
Fail safe operation
Wide low-voltage operation
Separate Power/Fail and Detect LEDs
LED Indicators: The green Power LED will be on steady to indicate the detector is operating and powered. In the case of a loop circuit or mini-loop 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.
The red Detect A LED will turn on when a vehicle is over the loop detection area. If delay is programmed, the LED will blink slowly during the delay interval. If extension is programmed, the LED will blink fast during the extension interval.
The red Detect B LED will echo the B output.
Sensitivity Switch: This detector has a 10-position rotary sensitivity switch. The unit is shipped in the “5” position which is the normal sensitivity level.
Sensitivity can be adjusted up and down from this level to accommodate different street loops or mini-loops.
Frequency: One of four operating frequencies can be selected by changing DIP switches 9 and 10
Loop Type: Turn DIP switch 8 off to operate with a normal inductive loop. Turn the switch on to operate with a Diablo Controls mini-loop.
Extended Presence Time: Turn DIP switch 7 off to hold a vehicle’s presence for about 20 minutes before tuning it out. Turn the switch on to hold it much longer.
Output B Control:
DIP Switches 6 and 5 (Effects output “B” only)
6 = OFF and 5 = OFF B output is normal presence output.
6 = OFF and 5 = ON B output is an “Entry“ pulse.
6 = ON and 5 = OFF B output is an “Exit” pulse.
6 = ON and 5 = ON B output is a “Fail” condition.
Sensitivity Boost: Turn DIP switch 4 off to operate with normal sensitivity. Turn DIP switch 4 on to automatically boost sensitivity during a call to improve detection of high-bed vehicles and truck/trailer combinations.
Sensitivity boost is not applicable to most situations.
Failure Operation: 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. Turn DIP switch 3 off to operate in fail safe mode. Turn the switch on to operate in fail secure.
Note: Never use a fail secure detector on a safety loop.
Output A Control
DIP Switches 1 and 2 (Effects output “A” only)
1 = OFF and 2 = OFF Output A normal Presence.
1 = OFF and 2 = ON Output A has 2 seconds of delay.
1 = ON and 2 = OFF Output A has 2 seconds of extension.
1 = ON and 2 = ON Output A has 5 seconds of extension.
Mini-Loop Operation: The mini-loop mode will always be an entry pulse. As such, it is perfect for free exit operation. Never use the mini-loop as a safety loop.
