Barrier Gate Systems 

Flat rated parking systems, like any other PARCS (parking access and revenue control systems) have barrier gates at two access points: entry lane and exit lane.

The difference between full-feature and flat-rated systems has to do with the number of equipment machines needed for the system to function. Full-featured systems require two machines: Entry BOXX and Exit BOXX. Flat rated systems only require one: Flat Rate BOXX.

In full-featured systems barrier gates connect to Entry BOXX on entry, and Exit BOXX    on exit. Both access points require a barrier gate and a parking machine. 

In flat-rated systems, only one access point requires a barrier gate & parking machine pairing. The other access point has a barrier gate that lifts automatically when it detects an oncoming car.

Systems designed for payment on entry will have a Flat Rate BOXXX and barrier on entry, and  an automatic barrier gate on exit. Parkers pay using Flat Rate BOXX before entry .

Systems designed for payment on exit will have an automatic barrier gate on entry and a Flat  Rate BOXX and barrier gate on exit. Parkers pay using Flat Rate BOXX  before exit .
