Controlled Entry - Free Exit:
"Controlled entry, free exit" is one of the most popular setups for automated gates. Safety and security coupled with convenience and comfort make this application ideal for residential and commercial automated gate projects.

|1 - Operator
(single or dual application)
1 - Time Delay
2 - Loops
2 - Vehicle Detectors
1 - Entrance Device*
1 - Three button Switch
*Note: Other entrance devices may be used,
The vehicle approaches the entrance and driver uses the entrance device, i.e. keypad, card reader, radio device. This creates an impulse which actuates the operator and opens the gate.
As the vehicle travels through the opening, it passes over the "outer loop" and "inner loop" creating an impulse to hold the gate open. When the loops have been cleared, the timer, after a preset period, sends an impulse to the gate operator to close the gate.
If the gate is closing as a vehicle reaches the loop area, the gate reverses to the open position and the timer automatically resets.
