The TOT-20RB is designed to provide an accurate unobtrusive barrier free count of patrons. Each lane uses two 8" round bollards to create the initial aisle way with one bollard added as the array expands. Each land includes a Programmable Logic Controller, entry and exit counters and dual PIR sensors. Separate entry and exit counts are provided at each lane. Counter outputs can also be connected to remote counting system. Standard aisle width is 22" but can be expanded to 36" to accommodate strollers and comply with ADA requirements without any decrease in accuracy. Typical applications include casinos, amusement parks, retail outlets, fairs and any other location where accurate, unattended bi-directional counting is necessary.
