National Sign offers the following lines of retractable vehicle access deterrence and denial barriers:

• High Security Model 400
• Traffic Control Model 100

National Sign’s retractable vehicle barriers were developed to address the need for intelligent area denial, perimeter security and traffic control applications. The Model 400 barriers are K12- and PAS 68-rated and are certified by governments in the United States and the United Kingdom to stop a 15,000 lb. vehicle traveling at 50 mph. The barriers deploy fully in less than 6 seconds in normal operation mode, and in less than 2 seconds in emergency operation mode. IPS Model 400 barriers are self-contained, eliminating the need for a central hydraulic pump station or underground lines. Each barrier has an independent Parker Hannifin hydraulic power system and all electromechanical components are housed directly next to each barrier, providing environmental protection and ease of access for maintenance or replacement. Model 400 barrier systems can be operated locally using a panel or keypad, or remotely using high-speed Ethernet radio or satellite communication. Remote monitoring of the system is possible through a secure web-enabled interface.

National Sign’s Model 100 retractable traffic control barriers are a safe and easy way to control or redirect traffic, particularly in situations where repetitive changes in lane usage or traffic flow patterns are required. IPS delineators eliminate crew exposure to hazardous situations during traffic flow changes by eliminating the need for workers to place pylons, drums or vertical panels. The delineators also have valuable security applications, including providing management or control of traffic around secure facilities (e.g., serpentine lanes), or as protection devices at railroad crossings. Additional applications include traffic flow management at toll collection lanes, weigh stations, parking lots, tunnel and bridge entrances, HOV lanes and reversible lanes. The delineators are flexible, but highly durable pylons designed to withstand repeated vehicle impacts. The barriers are housed in self-contained cartridges recessed in the ground and can be easily raised or lowered as needed. Each barrier can be individually controlled or controlled as part of an array of delineators that takes commands from a central control unit.

All IPS security barriers are shipped in a pre-fabricated, steel foundation, significantly reducing on-site installation requirements and cost. Additionally, the barriers operate on low power (24v) and each barrier has its own independent battery back-up system in case of power outages.
