The D3250 Automatic Barrier is a robust and versatile traffic control system designed for various access management applications. It is engineered for continuous operation with a 100% duty cycle, making it suitable for high-traffic environments. The barrier system is manufactured in the UK, emphasizing quality and adherence to European standards.
Function Description
The primary function of the D3250 Automatic Barrier is to regulate vehicle access. It operates by raising and lowering a boom arm, effectively controlling entry and exit points. The system can be integrated into various access control setups, including dual-height card access entry, loop safety/lower with auto loop exit, and more complex configurations like separate entry/exit barriers or twin barriers for wider spans.
The barrier is controlled by a PLC (Programmable Logic Controller) with a remote controller display, allowing operators to manage and adjust parameters. It supports various safety and operational features, including photocells, safety loops, and limit switches, to ensure safe and reliable operation.

Usage Features
The D3250 barrier offers a range of usage features designed for flexibility and ease of operation:
- Controller Display: The barrier is managed via a remote controller display, which provides access to various parameters, timers, and settings. The display allows operators to adjust opening/closing speeds, safety settings, and other operational aspects.
- Parameter Settings: Users can configure parameters such as "No Pass Timer" (to prevent immediate lowering after a vehicle passes), "Safety Reverse" (to raise the barrier if photocells are activated during lowering), "Loop/Photocell Close" (to close the barrier when a loop or photocell is activated), "Boom Lights" (for operating boom lights), "Flashing Boom Lights" (to flash lights), "Slow Down" (for controlled slowing), "Inverter Outputs" (for running an inverter hardwired), "Raise Timeclock" (to hold the barrier up at set times), "Auto Timeclock" (to disable the auto loop at set times), "N/O Safety" (normally open safety input), "Master/Slave" (for multi-barrier setups), "Traffic Light" (for traffic light output), and "Kerb Interlock" (for kerb interlock program).
- Barrier Timers: The system includes various timers that can be set up, including "Traffic light delay," "Lower delay," "No pass delay," "Mag delay," "Slow down delay," and "Raise delay timer." These timers allow for precise control over the barrier's movements and interactions with traffic.
- PLC Time Clock Setting: A built-in 24hr time clock allows for scheduling barrier operations. This includes "Raise Timeclock" (which holds the barrier up) and "Auto Timeclock" (which disables the auto loop). Users can set up to four periods for ON/OFF times and configure "period day set" to specify which days the time clock should be active.
- Manual Release: In case of power failure or maintenance, the barrier can be manually released using a key-supplied mechanism. This involves removing the cover and rotating a handle to release the boom. A safety switch prevents operation if the cover is not fully closed.
- Installation Flexibility: The barrier can be installed in various layouts, from basic single-entrance setups to complex multi-barrier configurations. The foundation layout drawing provides detailed specifications for ducting, wiring, and support structures.
- Accessories: A wide range of optional accessories is available, including folding bottom skirt, top/bottom skirts, bar arm up to 5.0m, articulated arm (low ceilings), std tip support, boom lights, magnetic lock, long/height stop/no entry signs, warning sounder/flashing beacon, and sensing safety edges.
Maintenance Features
Regular maintenance is crucial for the D3250 barrier's longevity and reliable operation. The manual recommends a bi-annual service, or at least once every 12 months, to ensure optimal performance and safety.
- Scheduled Maintenance: A maintenance contract is recommended, typically involving service every 5000 manoeuvres or annually.
- Photocell Cleaning: Photocell optical components should be cleaned every 6 months or sooner depending on use, as dirt, water, rain, soil, etc., can affect their functionality.
- Electrical Checks: Regular checks of the electrical clutch and power supply cable are essential. Any damage to the power supply cable should be addressed by a qualified technician.
- Gearbox Maintenance: The gearbox drive unit is "sealed" for life and does not require further lubrication.
- Fault Finding: The manual provides a comprehensive troubleshooting guide for both mechanical and electrical errors, detailing causes and corrections. This includes issues like barrier arm movement, motor operation, and PLC errors.
- Service Log: A dedicated service log is provided to record all maintenance activities, including dates, reasons for visits, and engineer signatures, ensuring a complete history of the product.
The D3250 Automatic Barrier is designed for durability and continuous operation, with a strong emphasis on safety and ease of maintenance, making it a reliable solution for various access control needs.
