CONTROL SYSTEMS
Barrier Control Systems
As a leader in the field of access control, Delta Scientific provides several options of barrier control systems to operate beam barricades, wedge barriers, crash gates, and retractable bollards. Using our high security access control systems, your security personnel can control these safety features to enhance facility security.
We can customize a system with hydraulic,electro-mechanical, or pneumatic capabilities with automatic or manual operation. With our equipment in place, your team can use touch screens, RFID readers, biometrics, keypads, or visual inspection to remotely control facility access. Explore the features, capabilities, and benefits of our high-security access control systems and enclosures.
Junction Box and Control Circuitry
Delta Scientific builds control circuits to meet project requirements. From simple to highly complex integrated systems controlling multiple barricade systems, our team can design and deliver the appropriate high-security access controls. We can accommodate U.S. and international voltages as needed.

Hydraulic Power Unit – Delta HPU
The Delta hydraulic power unit is the top-of-the-line in heavy-duty, patented barricade control systems. We rack and stack valves, flow controls, and accumulators to meet our clients’ applications for:
- Number of barricades to be controlled
- Operation speed
- Required power off cycles
The Delta HPU pump comes equipped with an integral tank, sight gauge, and level switch. Options include a hand pump and oil heater. The unit shown is a two-barricade system pump.
Electro-Mechanical Control System
Delta Scientific provides a series of electromechanical barrier control systems that take advantage of programmable logic controllers and motion control drives to create systems that operate flawlessly without hydraulic oil. The controllers and drives in the system allow for monitoring and diagnostics of the barrier system and handle all motion control.
Additionally, we can equip our electromechanical systems with a heavy-duty battery backup system that allows for over 100 cycles after power has been removed from the system. This is a critical component for facilities with unstable power supplies and those at risk of natural disasters.
Hydraulic Pump Enclosure and Housing
Our team designed the Delta HPU enclosures to withstand the harshest environments. HPU enclosures allow easy access to all the components from the front of the unit. We also offer optional side access doors to make servicing them easier.
We can paint our HPU enclosures to match any color so they blend seamlessly into the background. You can upgrade each enclosure to a heavy-duty version that includes bullet-resistant features and a stainless steel finish.
H8050 24v DC Powered HPU
The H8050 is a 24V DC-powered HPU that allows you to control barrier operation using standard 120V or 220V power. An integrated control circuit and upgraded accumulator can adapt to multiple barrier control configurations and higher duty usage.
This hybrid system can handle cycle rates of 2 seconds. Simply plug it into any standard 120/220V socket and you are ready to power your barricade. This HPU can also run directly off solar panels if a standard power source is unavailable.
H4050 12v DC Powered Hydraulic HPU
We created universal voltage DC-powered versions of the Delta HPUs for remote locations or less frequently operated barricades. These flexible barrier control systems feature long battery life, low amperage trickle charging, and solar panel charging.
Touchscreen Control and Data Logging System
Delta’s engineers can create convenient and fully customizable touchscreen control panels capable of controlling up to 8 unique barriers or systems on screens ranging from 8 to 20 inches.
The B5010 control panel is a customizable touch screen barrier control panel with a built-in data logging system. Delta designed the software from the ground up specifically to control our High-security barrier systems. Built-in Ethernet communication allows easy connection and integration into any networked barrier system.
We built dozens of options into the software to ensure that the control panel accurately matches your specific system setup. Large custom graphics ensure that any user can easily operate the barriers, and the built-in ability to create and remove users ensures that only those with certified access are able to control the system. Recorded cycle counts and maintenance alarms make it easy to ensure your barrier is properly maintained and functional when you need it to be.
Early Warning Systems
Using Doppler radar and digital loop detector tech, the Delta DSC400 early warning system alerts guards to active security measures and raises Delta vehicle barricades. Continuous Doppler radar picks up instantaneous changes in velocity and addresses the threat scenario in which an inbound vehicle approaches at normal speeds and then accelerates to commence the attack. It will also warn if a hidden vehicle suddenly passes a larger vehicle and attempts an attack. Once alerted, the guards can take action, including raising the Delta barricade systems.
The Delta DSC400 early warning system consists of radar antennas that look and install similarly to video surveillance cameras. They can be positioned on top of guard booths or on poles looking into the facility or out. The system includes the circuitry and logic to trigger an alarm panel when a preset speed is exceeded or when a vehicle drives in an exit lane while attempting to go around a guard booth.
Every second counts in an attack, and Delta answers the demand for immediate action with its DSC400 early warning system. The DSC400 is best applied at locations where there is a long and relatively straight run into the facility that would allow a large vehicle to build up its speed. A vehicle traveling at 60 mph (96 kph) can cover 88 feet per second (2.68 m/sec), making it imperative that the guards receive a near-immediate alert.
Vehicle Loop Detectors
Power outages can cause vehicle access barrier control systems to reset their logic, which often results in a barrier raising or lowering into position. Unexpected gate openings can cause accidents and security lapses. Delta loop detectors provide customers with a safety detector to reduce that risk because they are programmed to prevent a closing signal when power resumes.
Delta highly recommends the use of vehicle loop detectors to prevent accidental closings and openings when authorized vehicles move through high security access control systems, which can suppress the operation of heavy gates and vehicle barricades. Delta Scientific’s series digital loop detectors work with all Delta vehicle access barrier control systems and are directly interchangeable with most other brands as a plug-in replacement.
Typical digital loop detectors hold a gate open until the last part of a vehicle has passed the closing loop, located beyond the gate. The detector then gives a pulse on departure, instructing the gate to close after the vehicle has passed. Oftentimes, after power outages, the entire system needs to be reset. The LMA series negates this problem.
Delta loop detectors incorporate an advanced microcontroller that combines a powerful digital computer and the latest and most advanced inductive vehicle loop technology to give high-test reliability and accuracy when measuring, counting, or detecting vehicles. This ability helps avoid unexpected gate operations such as the raising or lowering of gate arms, sliding gate operation, motorized teeth, and barricade actuation.
Delta loop detectors provide input voltages of 24 VAC, 24 VDC, 120 VAC, and 230 VAC.
