DSP-11 LV Diablo Control Safety or Exit Loop Detector

This detector operates on any voltage from 10 to 30 volts AC or DC and draws about 35 milliamps of current with no vehicle on the loop. 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 Detec LED will turn on when 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 the traffic flow to continue. A fail secure detector will never output “detect” when the loop circuit 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 on a safety loop.

“We are always getting questions about how gate exit wands work and how they are different from exit loops.

Exit wands are what is know as a magnetometer which senses changes in the Earth’s magnetic field. An easy way to explain how exit wands work is to picture a boat traveling through the water. As the boat is traveling it is creating waves. As your car travels through the magnetic field of the Earth it creates similar waves, like the boat. The exit wand’s magnetometer picks up on these waves as you travel by the wand. One downside of exit wands is that they do loose sight of your vehicle when it is stopped.

Gate Crafters carries 5 different types of exit wands that work very similar to each other. The only difference between these wands are some of their features. The GTO/PRO wireless exit wand is wireless between the magnetometer and receiver. The Gate Crafters exit wand is manufactured by EMX and has been around for years. The GTO exit wand is recommend for use with other GTO openers and accessories. The Estate Swing exit wand does come with a range control board that allow you to adjust the sensitivity of the magnetometer. This feature allows you tune down the range of the exit wand, so that vehicles such as a lawn mower doesn’t set open your gate, but this isn’t a complete failsafe, as it will still operate the gate opener when something is nearby. The Estate Swing Deluxe Exit wand is the most different from the other exit wands. It is constructed out of copper and features a ground cable that attach to a grounding rod that helps protect this exit wand from lightning strikes. The other 4 exit wands do not have this feature and are susceptible to damage from lightning strikes. Also the Estate Swing Deluxe Exit Wand comes with a 5 year warranty, which is longer than any other exit wand we sell.

Exit loops differ from exit wands in that they are buried in the driveway in a loop and are wire to the gate opener. The way exit loops work is that they detect the presence of metal (your car) above the loop. It does not matter if your car is moving or not, the loop will detect the car. Besides being used to exit your property, exit loops are used for safety. When exit loops are used a safety device, they will prevent your gate from closing on your car, when it detect a car nearby to your gate. The exit loop is wired to a exit loop detector, which is then wired into your gate opener’s control board.
