Fixed Bollard Modules – DSC305
Features
DSC305 Automatic Retractable Bollard System
The model DSC305-PE Bollard System (“DSC305”) is engineered to provide positive control of vehicles entering or exiting restricted areas. Powered by a quiet pneumatic power system, these automatic retractable bollards deliver fast operation and building protection for high-security facilities, commercial sites, and controlled-access lanes.
Designed for both flexibility and performance, the DSC305 can function as a standalone traffic controller for a single lane or manage multiple lanes of bi-directional traffic.
Each unit uses precision-machined steel bollards that raise and lower smoothly. When in the guard position, DSC305 bollards form a formidable defensive barrier that can absorb and transfer impact energy directly into the system’s foundation, helping stop unauthorized or aggressive vehicle attacks.
DSC305 Precision Steel Bollards
High-Security Bollards for Controlled Vehicle Access
Initially developed for high-threat environments, the DSC305 is a high-security bollard capable of stopping and disabling a 4,500-lb (2041-kg) vehicle traveling at 20 mph (32 kph). This makes the system ideal for government facilities, critical infrastructure, commercial sites, and industrial operations where dependable vehicle control is essential.
The DSC305 may be used as:
- A standalone automatic bollard for single-lane access
- A multi-bollard array for multi-lane traffic control
- A coordinated system with bollards operating individually or as synchronized sets
This flexibility allows the retractable bollard system to meet a wide range of operational and security requirements.
Automatic Retractable Bollard System With Engineered Pneumatic Power
Automatic Retractable Bollard System With Engineered Pneumatic Power
Each DSC305 system is powered by a Pneumatic Power System (PPS) that includes the compressor, air-treatment components, valves, and integrated control logic. The PPS may be installed indoors or within a weather-resistant enclosure for outdoor setups.
Key operational advantages of the automatic retractable bollards include:
- Smooth, quiet raising and lowering
- Adjustable operating speeds, typically 5–10 seconds
- Ability to manually operate valves during power outages
- Customizable throughput rates and power-off operation cycles
These features make the DSC305 one of the most reliable and environmentally friendly retractable bollard solutions available.
Options for Fixed and Retractable Bollard Systems
While the DSC305 is primarily known as a retractable bollard, it also works seamlessly with DSC305 Fixed Bollard Modules to support mixed installations where both permanent and retractable barriers are needed.
This allows facilities to design access points that combine:
- Permanent fixed protection
- Retractable access lanes
- Coordinated systems that share common control logic and power infrastructure
Mixed systems provide a balanced approach to perimeter design, delivering both flexibility and immovable strength where required.

Flexible Access Control for Real-World Applications
Because the DSC305 can operate individual bollards or synchronized sets, it adapts easily to different traffic patterns and security procedures.
Remote Lock-Down Protection
Under remote lockdown, DSC305 bollards can secure parked vehicles or prevent the movement of passenger cars, trucks, trailers, and industrial equipment. When installed in front of a warehouse door, these retractable bollards make unauthorized large-vehicle access extremely difficult.
VIP and Reserved Parking Control
Authorized drivers or remote operators can raise or lower individual bollards, allowing secure, managed control of dedicated or VIP parking spaces.
Gate System Integration
When installed alongside a pedestrian gate or guard-operated drop arm gate, the DSC305 adds an additional layer of security by remaining in the raised guard position until an operator approves the visitor, which helps prevent gate-running incidents.
Sally Port Configurations
Arranging DSC305 bollards as a Sally Port helps eliminate tailgating and improves perimeter security by forcing vehicles to move through controlled stages.
