At commercial and industrial entrances, installing two boom gates is only one part of the project.
For a dual boom gate installation in Marsden Park NSW, the more important engineering challenge is ensuring the barriers can operate as one coordinated access system.
The controllers, safety devices, vehicle detection and operating logic need to work together so the two boom gates respond correctly to access commands and site conditions.
At first glance, the concept seems simple:
Press the access command and both barriers open.
But the real engineering question isn't simply:
“Can we make both boom gates open?”
It's:
“How should the complete system behave under normal operation, safety conditions and emergency situations?”
Planning a Commercial Boom Gate Project?
Commercial vehicle entrances can require more than simply selecting a boom gate motor.
Where multiple barriers, vehicle detectors, safety devices and access-control systems need to work together, the operating strategy should be considered as a complete system.
Gate Automation NSW can assess the entrance, vehicle movements, access-control requirements and required operating sequence before recommending an appropriate solution.

Why Would Two Boom Gates Be Required?
There are several situations where two automatic boom gates may form part of a single vehicle-access system.
These can include:
Wide entrances
Multiple traffic lanes
Entry and exit arrangements
Commercial facilities
Industrial sites
Transport facilities
Car parks
Security-controlled vehicle entrances
Commercial and industrial facilities around Marsden Park and Western Sydney can also have complex vehicle movements involving staff, contractors, deliveries and visitors.
The physical layout, however, is only one part of the design.
The next question is how the two barriers should interact.
Should they always operate together?
Should they sometimes operate independently?
What happens if one barrier develops a fault?
What happens when a safety device is activated?
What happens during a power failure?
Those decisions should form part of the system design.
Two Boom Gates Don't Automatically Make One System
Two independently installed boom gates can each operate correctly while still not functioning as a properly coordinated entrance.
For integrated operation, there needs to be an appropriate method for the controllers to exchange or respond to the required commands.
Depending on the equipment and system architecture, this may involve:
An SIS card
Manufacturer-supported integration card
Interface module
Appropriate control connections
Another supported communication method
The exact solution depends on the equipment and the required operating logic.
The objective is to coordinate both barriers without compromising the control and safety requirements of each operator.
Controller Logic Is the Foundation
The controller determines how each boom gate responds to incoming commands and safety inputs.
For a dual boom gate installation, the control strategy may look something like this:
Access command received
↓
Controllers respond
↓
Opening sequence begins
↓
Both boom arms reach the required open position
↓
Vehicle moves through the controlled area
↓
Vehicle detection and safety conditions are satisfied
↓
Closing sequence begins
↓
Both barriers return to the closed position
The exact sequence depends on the equipment, entrance layout and site requirements.
But thinking through the complete operating cycle is essential.
What Does an SIS or Integration Card Do?
Where supported by the selected boom gate equipment, an SIS or other integration card can provide communication or synchronisation functionality between controllers.
Rather than treating each boom gate as a completely independent machine, the control system can coordinate the required behaviour.
However, installing an integration card alone doesn't complete the system.
The correct:
Connections
Controller settings
Programming
Operating logic
Safety inputs
Vehicle detectors
Access-control inputs
still need to be configured and tested.
Integration hardware enables communication. Correct system logic determines how the entrance actually behaves.
Should Both Boom Gates Open at Exactly the Same Time?
Not necessarily.
The correct behaviour depends on the application.
Some installations may require simultaneous operation.
Others may require a particular sequence or delay.
The appropriate behaviour should be determined from:
Physical entrance layout
Vehicle movements
Boom arm positions
Access-control strategy
Safety requirements
Controller capabilities
This is why synchronisation should be designed around the actual site, rather than simply assuming identical movement is always the correct solution.
Safety Inputs Are a Critical Part of the System
Safety is an important consideration in any automatic boom gate installation.
A dual boom gate arrangement can incorporate devices such as:
Photoelectric safety beams
Vehicle detection loops
Radar detection
Appropriate safety inputs
Emergency controls
The control logic needs to determine how the barriers should respond when one of these inputs changes state.
For example:
What happens if a safety beam is interrupted during closing?
Should both barriers respond?
Should one barrier respond?
What should happen to the operating sequence afterwards?
Vehicle Detection and Dual Boom Gates
Vehicle detection can play an important role in determining when the barriers should open, remain open or close.
Depending on the application, vehicle detection may involve:
Radar sensors
Safety beams
Access-control inputs
Detector positioning is particularly important.
A detector positioned incorrectly can affect how the overall entrance behaves.
For a dual boom gate installation in Marsden Park, the relationship between the vehicle path, barriers and detection zones should therefore be considered as part of the complete system design.
Entry and Exit Logic
Not every dual boom gate installation uses both barriers in exactly the same way.
For example, an entry sequence might involve:
Authorised credential
↓
Access command
↓
Boom gates open
↓
Vehicle enters
↓
Safety/detection conditions satisfied
↓
Boom gates close
An exit sequence could instead involve:
Vehicle approaches
↓
Vehicle detector activates
↓
Automatic exit command
↓
Boom gates open
↓
Vehicle exits
↓
Detection zone clears
↓
Barriers close
The actual sequence should be designed around the site's traffic and access requirements.
Integration With Commercial Access Control
The boom gates may receive commands from several different access-control technologies.
Depending on the project, these can include:
Keypads
RFID cards
Fobs
Remote controls
GSM systems
Video intercoms
ANPR/LPR
Timers
Building/security systems
Vehicle detection
The integration needs to establish:
Which input should cause which action?
For example, visitors may require authorisation through an intercom while authorised staff use a credential.
Outgoing vehicles may operate through automatic vehicle detection.
The boom gates therefore become part of a wider commercial access control system, rather than simply two standalone barriers.
What Happens During an Emergency?
Emergency behaviour should be considered during the system-design stage.
The appropriate response depends on the particular site, equipment and emergency-access requirements.
Questions can include:
What happens during a power failure?
What happens if one boom gate develops a fault?
Can the barriers be manually released?
How should authorised personnel operate the system?
Does another building or emergency system need to provide an input?
What state should the barriers adopt under a particular emergency condition?
These questions are better resolved during design and commissioning than discovered during an actual emergency.
What Happens During a Blackout?
Where battery backup is incorporated into the boom gate system, its condition and expected operation should also be considered.
Having backup batteries installed doesn't automatically prove that the barriers will operate correctly when mains power disappears.
Battery age, charging, connections and actual operation under backup power may need to be tested.
Manual Operation Still Matters
Even a sophisticated integrated system needs an appropriate strategy for situations where normal automatic operation isn't available.
Manual-release functionality should therefore be understood and tested according to the installed equipment.
Commissioning Two Boom Gates
Commissioning is where the complete system design is proven.
It isn't enough to operate the barriers once and confirm that both arms move.
Testing should verify the required operating behaviour across multiple cycles and relevant scenarios.
Depending on the installation, commissioning can include:
Individual barrier operation
Coordinated operation
Opening sequence
Closing sequence
Access-control commands
Safety inputs
Vehicle detection
Emergency/manual operation
Fault response
Multiple operating cycles
Final handover
This is particularly important because some problems may only become visible during a particular combination of inputs.
Why Multiple Operating Cycles Matter
One successful cycle doesn't necessarily demonstrate that a commercial access system is ready for service.
The system needs to operate consistently.
Repeated cycling allows the technician to observe:
Timing
Synchronisation
Detection
Boom arm movement
Controller response
Safety behaviour
Access-control response
This can help identify configuration issues before the system is handed over.
Maintenance of Dual Boom Gate Systems
Once commissioned, integrated boom gates should also be maintained as a complete system.
Maintenance isn't limited to lubricating mechanical components.
Depending on the installation, servicing can include:
Barrier mechanisms
Boom arms
Motors/operators
Controllers
SIS/integration cards
Safety beams
Vehicle detectors
Induction loops
Access-control inputs
Manual releases
Battery backup
Final synchronised operation
For commercial entrances, the objective is to consider how the whole access system is performing rather than treating every component in isolation.
