4. TRAFFIC TECH Traffic Innovations Surface mounted switch pads User Manual 1 Introduction EzyLoops Systems Surface mounted Pedestrian Activated Switch Pads are a pressure activated electronic method of detection that provides both passive presence detection and directional detection of pedestrians and vehicles Used with the Nortech PD134TLC Tactile Loop Controller the system has been designed to provide specific logic outputs from the patented tactile Switch Pad intended primarily for pedestrian detection The Switch Pad may also incorporate an inductive loop for vehicle detection Due to the combination of vehicle and pedestrian detection capabilities the tactile loop controller and Switch Pad can be used in a number of applications in low speed low volume car park traffic and pedestrian control applications as follows a Vehicle detection by means of the pressure actuation due to the vehicle wheels on the tactile sensor OR by use of the optional built in inductive loop OR a combination of both b Pedestrian Detection by pressure actuation The controller is capable of providing timing functions delay of the pedestrian actuation c Movement Direction detection in analysing the movements over the Switch Pad to determine direction of movement in both vehicle and pedestrian modes 2 Hardware Detail 2 1 Switch Pad EzyLoops Systems Surface mounted Pedestrian Activated Switch Pads are
