Manufactured at Aldridge and designed to be interchangeable with options of Polycarbonate, Aluminium or “Go Green’ Enviro” housings.
LED Standman and Walkman lanterns are designed using the same modular construction and components used to produce the Aldridge range of vehicle lanterns. Many parts of the housing are interchangeable.
Pedestrian lanterns are typically supplied complete with rectangular visors.
Two basic optical systems are available, Blue/Black backs and reflector carrier options.
Aldridge Pedestrian Count-Down Display (PCD) utilises the latest in microprocessor and LED technologies to provide a cutting edge product.
The Pedestrian Countdown Timer (PCD) has been manufactured under the operation of Pedestrian Traffic Signals in RTA Specification TSC/4. The PCD is powered by 240V AC (or 42V AC in 42V AC version), which is taken from the signal lantern (typically the RED standing man / Don’t Walk lantern used to flash the clearance period).
No programming is required for the PCD as it auto-detects the flashing clearance period. Auto-detection occurs for at least one complete cycle before displaying the correct countdown sequence on the following cycle. Timing and synchronisation with the flashing clearance is taken from the flashing lantern (typically the RED Standman / Don’t Walk lantern is used to flash the clearance period).
Mounting the PCD is standard, designed to mount into existing Traffic Signal Housings and can be provided with or without the step down transformer.
The PCD is typically used with standard Pedestrian Traffic Signals to indicate of the remaining time for the flashing clearance period. The two-digit display only lights during the flashing clearance period and displays a countdown of the remaining seconds for the clearance period. The PCD is blank during the GREEN Walk period and RED Don’t Walk Periods.
A configuration jumper is used to enable or disable leading zero-digit blanking. Leading zero blanking provides additional visual feedback to distinguish clearance periods below 10 seconds.
