Loop systems, although more common for commercial gates in Houston, are becoming increasingly desired for residential driveway gates, and for good reason. When you drive your car up to a gate and it automatically opens in front of you or closes behind you, a built-in loop system may be responsible. There are different types of loop systems that may be installed for residential and commercial driveway gates.

Exit Loop

An exit loop is a device that detects a vehicle when it drives over the exit loop and signals the gate to open. The exit loop allows for greater convenience as a vehicle attempts to exit the premises opening the automatic driveway gate for it to pass through without the need for a remote control, keypad or any other security device. A exit loop contains a loop detector that is hidden underground and is triggered as a vehicle drives over an inductive loop, sending a signal to the gate to open.
The loop is installed in a location that will allow the driveway gates to open at the proper time without the driver of the vehicle having to wait for the gates to finish opening before reaching them. The ideal location for installing the exit loop is always dependent on the property, the speed of the approaching vehicle as well as other factors so the exit loop acts properly without unnecessary delay to departing vehicles.

Safety Loop

Safety loops are also referred to as Reverse loops. They keep your automatic driveway gate open or reverse the gate if it is closing when a vehicle is detected. Safety loops can offer peace of mind and prevent risky scenarios where a person may panic if their vehicle is in the pathway of a closing driveway gate. Here are a few situations where reverse loops are important:
Vehicle tailgating/follow-through. One vehicle following closely behind another vehicle whereas the automatic gate may close on the secondary vehicle.
An object may block the path of a vehicle passing through the gates leaving the vehicle in the path of a closing gate.
A guest leaving the property may not be able to move their vehicle out of the path of the automatic gate in time due to traffic or other circumstances.

Shadow Loop

A shadow loop is placed under the path of a swing gate. It is important to know what a shadow loop is and why it very important. This loop will check the gate before it closes or opens to make sure that a vehicle is not in the swing path and if a vehicle is in the swing path the gate will not move. A shadow loop is very important, as a vehicle can be located inside the path of the swing gate which would allow the gate to close on the car if the shadow loop is not installed for this application. This protects guests and visitors alike from the gate striking their vehicle accidentally.

Exit Wand Sensor

Exit wands are typically used on rough finished roadways or gravel roads that are not maintained regularly or on the side of a finished driveway where changes to the driveway are not advantageous. the preference is to avoid modifying the existing asphalt, concrete, or paver roadway. An exit wand can be placed on the side of a driveway exit area rather than in the center of the road which makes this an attractive option due to the installation cost and ease of installation. Because they can be placed on the side of the road rather than in the center of the roadway it can greatly reduce installation costs. Exit wands should not be used for safety purposes as exit wands are not designed for that. The gate can have false triggers due to animals walking past the exit wand triggering the gate to open.

With many loop systems for different purposes, it can be difficult to determine which is best for your particular residential or commercial gate.
