Exit Loop Detector

An exit loop detector is a system designed to automatically open gates or barriers for vehicles leaving a secured area. It works primarily on the principle of electromagnetic induction and is a common component in automated access control systems for driveways, parking lots, and commercial properties.

Here’s how it generally works:

Inductive Loop: A wire loop, usually rectangular, is buried beneath the surface of the driveway or exit lane. This loop is connected to a loop detector unit.
Electromagnetic Field: The loop detector sends an alternating current through the wire loop, creating a continuous electromagnetic field around it.
Vehicle Detection: When a vehicle (which contains a significant amount of metal) drives over or within the range of this electromagnetic field, it disrupts the field. This disruption causes a change in the loop’s inductance.
Signal to Gate Operator: The loop detector senses this change in inductance and sends a signal to the gate or barrier’s control system.
Automatic Opening: Upon receiving the signal, the gate operator is triggered to open, allowing the vehicle to exit without requiring a remote control, keypad, or manual intervention.

Description

Exit Loop Detector

A exit loop detector, also known as a free exit loop, is a system that uses a buried wire loop and a loop detector to automatically open a gate when a vehicle approaches from the exit side.

The underground exit loop detector allows vehicles to leave a property without needing to operate a remote control, keypad, or other security device.

How it works:

1. Loop Installation:

A wire loop is installed in the driveway, typically in a rectangular shape, and connected to a loop detector.
2. Vehicle Detection:

When a vehicle drives over the loop or is within its detection range, the loop’s inductance changes, which is detected by the loop detector.
3. Gate Activation:

The loop detector sends a signal to the gate operator, causing the gate to open automatically, allowing the vehicle to exit.
4. Safety Feature:

Exit loops can also act as safety devices, preventing the gate from closing on a vehicle that is still in the exit path.

Benefits:

Convenience: Provides a seamless exit for vehicles, especially for guests, delivery drivers, or visitors.
Automation: Eliminates the need for manual gate operation on exit.
Safety: Helps prevent accidents by ensuring the gate remains open while a vehicle is exiting.
