Gate barrier is widely used in commercial and residential buildings to control vehicular access. If you are a system integrator or gate automation installer or even a gate barrier distributor (like Stebilex), it is important to know how to select the best gate barrier system on behalf of the customer. Majority of the datasheets and catalogues are not really useful unless you already know what you are getting into.

What is your use case?
Application
Before purchasing a boom gate, one has to decide where it will be installed, and the operating model. There are boom gates that are specifically designed for a simple application like parking areas, traffic control to the large railway and industrial crossings. It is necessary to understand the application, space availability and use frequency.
![Complete guide to buying a gate barrier in 2020 banner 2](https://stebilex.com/wp-content/uploads/Complete-guide-to-buying-a-gate-barrier-in-2020-banner-2.jpg)
Ask Your Client
Is it for commercial or industrial or residential use?
Is it for heavy traffic or low traffic area?
Frequency of operation (Duty Cycle)
The duty cycle or frequency of operation of a boom gate is another factor that must be taken into account.
What is the duty cycle? The duty cycle for an automated gate operator is the number of times the gate can open and close without overheating the motor. Duty cycle is normally expressed in percentage. 100% duty cycle is meant for continuous use, eg: high intensive use cases like a shopping mall, toll plaza etc.
There are two most common categorisations: Residential(40-70% duty cycle) and commercial(100% duty cycle). As you can imagine, a gate barrier in a mall will be used much more time than one in an apartment. When calculating the required duty cycle, calculate for the worst-case scenario.

Ask Your Client
What is the average usage(open/close cycle) per day? (consider worst-case scenario)
Barrier operator
Barrier operators mostly come housed in the barrier body mounted on the floor or foundation plate. The barrier operator usually comes with a motor that operates on either hydraulic or electromechanical motors. Some latest products like FAAC b680H also have hybrid motor technology with a Hydraulic Brushless motor in one barrier operator. Hydraulic motors are usually more suitable for heavy-duty, high frequency usage.
Hydraulic vs Electromechanical Motor
Hydraulic Motor
- Hydraulic controllers are very reliable and pose very few maintenance issues if installed properly.
- They are a very effective deterrent in case a vehicle runs into the barrier or in stopping tailgating vehicle.
- Cold can be a problem; too cold weather can cause oil thickening in the hydraulic unit. However, this can be solved with a temperature control unit.
Electromechanical Motor
- The electromechanical unit is much quieter than the hydraulic motor.
- A bit slower than Hydraulic but they offer more control, one can set variable speed for how quickly the beam rises.
- Most security professionals find the electro-mechanical unit easier to maintain.
- The Electro-mechanical units require at least 220v/single-phase power, which is typically 12-15 more amps of power than what the hydraulic motor requires.
What are the physical attributes of the preferred vehicle barrier?
Arm length
Boom gates come with different beam lengths and boom barrier shapes to suit the width of the passage you wish to control. Beam length from 2 metres to 12 to 13 metres, which are especially suitable for use when companies have oversized vehicles, such as mine sites and rail crossings. They come in round or rectangular shapes, wherein rectangular is a bit more expensive.

Ask Your Client
What is the drive-way width?
Arm articulation
Arm articulation makes it possible to articulate the rigid beam to a maximum height according to the ceiling. They are used in parking garages or in areas with limited or low overhead clearances.

How do you want to control access to the facility?
Barrier access control
Another most important requirement you need to decide is how you want to control the boom barrier – with reader, remote controller, or push button. They can be configured with UHF readers and tags, with a control switch for security officers, remote controllers and receivers, or with push buttons or biometrics.
![](https://stebilex.com/wp-content/uploads/fingerprint.png)
Biometrics readers:
The barriers can be controlled with biometric-readers like fingerprint, face, Iris options.
![](https://stebilex.com/wp-content/uploads/credit-card.png)
Swipe Card Readers:
Access control via RFID cards. Type: Magnetic, proximity cards, and proximity cards with a magnetic stripe, key-chain FOB.

Switch to Exit Button:
For the facility security team to control the to and fro access.
![Complete guide to buying a gate barrier in 2020 banner-7](https://stebilex.com/wp-content/uploads/Complete-guide-to-buying-a-gate-barrier-in-2020-banner-7.jpg)
Ask Your Client
Is the entry/exit point manned, does the security team need an exit button for the manual opening?
What kind of access control is required to the facility – biometric or remote or ANPR or RFID tag or swipe card based?
Safety features to consider
Anti-crushing sensor
Gate barriers feature safety components like sensors for automatic detection of approaching vehicles, anti-crushing sensors that reverse the beam on impact if the barrier boom automatically closes on the vehicle. The anti crushing sensor only stops repeated impact only after hitting the object once. That’s why you need to have an additional detection mechanism in place – Photocells.
Photocells
Photocells (motion sensors) are electronic devices that improve security by automatically detecting vehicles or obstacles to enable automatic rising of booms. This infrared setup will have a transmitter and receiver at each of the ends of the driveway and whenever an obstacle is detected the barrier will prevent the gate from closing and raise the barrier boom.
Loop detector
Barrier gates come with other solutions like vehicle detection loops (inductive loop), which are installed on the barrier that detects vehicles and passing or arriving at a certain point. The loop detectors are connected to create a magnetic field, and the vehicle is recognised when it enters this field.
Additional features to consider
Battery back-up
If you want the barrier to operate even at the time of main power failure. Look for a continuous duty cycle(in hours) supported by the battery backup.
Opening and closing speed
Most conventional barrier gates provide running speed from 1.5 seconds to 6 seconds.
![Complete guide to buying a gate barrier in 2020 banner 8 1](https://stebilex.com/wp-content/uploads/Complete-guide-to-buying-a-gate-barrier-in-2020-banner-8-1.jpg)
Ask Your Client
What is the average opening time?
Look for 1.5 seconds+
The shape of the boom/beam
The barrier beams come in round, rectangular shape.
Support for modular beam/boom
What if the barrier needs more length than the standard beam length? When there is support for modular beams, the total length can be extended. Look for a boom extension set.
Colour of the gate barrier
Many manufacturers support your preferred colour for the enclosure. Ask for the supported colours.
International standards or regulations
Look for compliance with international standards(European/ISO) when it comes to safety and quality.
Maintenance and operating cost
You can always buy a cheap gate barrier but watch out for maintenance and operating cost. Operational cost is as important as the capital cost not just in terms of money but the availability of spare parts and technicians.
Enclosure rating
Gate barriers are of course installed outside and the motors and the other internal components should be protected from dust, water and other solid objects. Look for the international standard Ingress Protection(IP) ratings like IP 54 or IP 56.
Temperature Range
Again consider the worst-case scenario, watch out for maximum and minimum temperature tested and supported. Look for -20°C ÷ +55°C.
Integrated flashing traffic light and reflector kit
These optional modules help especially at night.
Anti-vandalism valve or Anti-panic unit
Most barriers come with safety features that stop forced opening or closing, and the anti-vandalism valve protects the hydraulic system in case the beam is forced. While an anti-panic unit is used for the manual opening of the barrier arm in the event of a power failure. Since an anti-vandalism valve prevents manual/forced movement of the beam, both anti-vandalism and anti-panic units cannot be installed together in a barrier system.
Pedestals
The pedestal is required when you need support for holding the access control device. For truck entry gates you need a dual height pedestal while a single height pedestal is used for car access.

Use Cases and Suggested Gate Barriers
For high-frequency and limited space
Buying a barrier gate for under-ground or multistoried car parking lots presents the challenge of limited space and high-frequency usage. Most of these structures need continuous opening and closing of barrier gates. Some of the must-have requirements for these facilities are – 100% duty cycle, arm articulation and easy access control system integration.
Recommended products:
For high frequency wider space
For the installation at traffic junctions and toll gates on highways, there is a requirement for barriers that support the lifting of extended boom lengths. They are required to block access to tunnels and lanes but also to manage traffic junctions with alternating traffic flows. Some of the must-have features you should look for include – 100% duty cycle, Traffic lamp integration, support for extended beam sizes.
Recommended products:
For long life and energy efficiency
Commercial use barrier gates are used very frequently and require constant energy supply. Two most important features required by the barriers operating in such operational environments are long operational life and energy efficiency.
