What is Trisign?


  • Trisign is the award winning safety product innovation of 2022, a changeable message sign allowing you to quickly change the sign scheme of a traffic management worksite - designed specifically for temporary traffic management.

  • TriSign is low power and runs off solar and on board battery. No need for a hard wired power supply

  • TriSign is a direct replacement for pole mounted temporary traffic management (TTM) signage for project sites

  • TriSign allows you to have 3 setups available at the push of a button (typically):


    Traffic Guidance Scheme 1 (eg: left lane closed)

    Traffic Guidance Scheme 2 (eg: right lane closed)

  • Trisign is app driven using our custom built Android app and takes around 30 seconds to switch between schemes

  • TriSign is secure, meaning only registered users with the appropriate permission set are able to activate signs / schemes

  • TriSign collects data from all interactions with users including its GPS location, date and time of activation, from what sign to what sign and the user who activated, meaning your record of signage report can be easily populated

  • TriSign is configured through SmartSite, a web app allowing you to add / remove users, create / alter sign groups and permission sets for users / sub contractors on your sites

Admin Support

For when you need to add or remove workers or move signs around, we have your back.

Why Trisign?

  • Eliminates the risk to workers on foot during sign cover / uncover or install / packup

  • Eliminate risks to pre-warning vehicle operators in high speed zone shoulders unprotected

  • Enables full, documented control over sign scheme changes

  • Android app and web app for remote site monitoring

  • Guarantees more production time on the road every shift


You will save up to 45+ minutes at the beginning and end of shift on a typical multilane setup.


90 mins per shift. 5 shifts per week. Av. 40 work weeks per year. 

That is an extra 35 work days every year. Without doing the OT. 


Features & Specs



TriSign utilises an ACMA approved communication method and able to achieve a range of 4km line of sight.

App communication is through bluetooth to the nearest device or via a TriLink device for your car or office. This allows remote access to the sign scheme from nearby site offices or from in vehicle during initial stages of site setup. 


Power Source

The 12V 10Ah, LiFePO4, military spec, on-board battery pack is supported with solar charging allowing for extended on site use with no need for a hard wired power source. Under normal operation, the TriSign can remain powered up with just 1 hour of sunlight daily. 



The TriSign should be considered an IoT (internet of things) device. All signs in range create a mesh network allowing sign change instructions to be sent over a significant distances through other signs to complete the required actions. 


Operating Life

We have tested the sign change mechanism through constant running of the device in controlled conditions, however have also achieved over 13,000,000 rotations on individual signs installed on live works sites that have been constantly rotating. 


Sign Face Options

Sign face formats are recommended to be designed in multi message format, however we can customise sign faces to suit your needs and even include public road safety announcements or other signage as required for any blank faces in the sign scheme.


Installation Types

Designed for permanent installation on project sites, TriSign comes with sign rails top and bottom. We can also design legs or other installation methods for PCBs or guard rail structures should you require. 


Associated Tech

TriSign is the the first device to become part of the SmartSite suite of connected devices. Activation of the TriSigns requires the TriSign app available for Android devices. Management of the devices or your sign schemes is possible through our web app SmartSite.



All users are required to be registered and permissions set for specific signs or groups of signs. 


Optional Extras

  • Signs can be fitted with beacons on 15 minute timers for activation warning / condition change for motorists.

  • TriLink device to extend the range of your site

  • Custom mounting options.

  • Hard wired options for locations that suit this need

  • Solar panel upgrades for shaded areas

  • What is the best mounting option for TriSign?
    The best mounting option is similar for long term multimessage signage- 2x 50mmNB bosts with concrete footings. We install sign rail to the rear of our frame so all the sign rail hardware options available for you to utilise. You could also use TD1 brackets and our custom Z bracket to install also.
  • How is TriSign powered?
    Trisign is battery powered and solar recharged. The standby current draw is 80mA and spikes to ~1A when the motor is operating for approx 12-24 seconds twice per shift. The battery is a 7.5Ah pack and solar panel is currently 14W, so we expect indefinite power supply even during periods of poor sun weather.
  • I imagine one administrator to change settings, then a traffic controller could adjust onsite as required?"
    Spot on. We would give you an 'owner' profile which will allow you to create, edit and see all sign groups and signs that have been assigned to you. You can then create 'Worker' profiles which are attached to your Owner profile and set permissions per user. eg: is worker#1 only needs access to site#A but not site#B and site#C, these permissions can be set for individual worker profiles. These profiles also have no access to edit or change signs in groups, just the ability to activate the sign face options.
  • The change of sign is via Bluetooth signal from a phone or tablet, so we need to issue command within 20m or so. Is this right? "
    The tablet / phone will connect to the nearest sign or TriLink by bluetooth, however the signs talk to each other through a 2.4GHz, ACMA approved radio network with an effective range of approx 1km line of sight. The idea being, a worker user pulls up at the first sign and the app connects to it via bluetooth, then all signs will show up as available to change. The 2.4GHz network is a true mesh network, meaning you can spread your signs across a 10km stretch of road, as long as you have a string of signs which can talk to each other. eg: if you have signs 1, 2, 3, 4 and 5 installed 1km apart, sign 1 cant talk directly with sign 5, but it will communicate through signs 2, 3 and 4 to reach it. Our Trilink device is a device we can add to the network as a range extender - these can be plug in or solar and pole mounted and can be added between sign groups or extended ranges, around obstacles etc to allow the network to extend and cover all of your site.
  • Does one phone/tablet control all or can several devices change displays?
    The app can be downloaded by any Android device and a user is required to log in to use it. Several devices can be used to activate and report on signage status, the only caveat is that the signs and TriLink can only handle 1x bluetooth connection at a time. So if multiple users were accessing the sign network from various locations around the site, possibly activating different setups, then this is a designed for use case.
  • It appears that you get a battery status of each sign on the app, is this correct?"
    Yes, this is present in the app and gives a battery health check for eac sign just to confirm that the installation location is suitable for solar charging sustainability.
  • If a battery is not charging correctly or the panels not functioning correctly, can the signs be changed manually?"
    Yes, we have a device called the Master Key. Each sign is installed wit ha cable and connector zip tied down the roadside installation post. A user can connect the Master Key and bypass the controller and battery to directly drive the motor to change the sign.
  • Can I change the TriSign display or does this have to be done on initial hire?
    We will set up the sign faces for you upon order. We have a magnet system to allow you to order sign packs from us which you can change on site yourselves. This is standard for the shipments of TriSign. When changing the sign faces, setup will be required in the web app by your admin user to adjust the images and descriptions for each sign so they display correctly in the app.
  • What is a typical lead time from confirmed order to operational delivery?
    It is currently an 8-10 week delivery timeframe dependant on delivery location and sign volume required.
  • Is the system secure. i.e can someone unauthorised change signage?
    Our system sits behind secure user login and our app is required to send / receive specific coded instructions. The network validates instructions based on a checksum for secure data transfer and to know when to ignore interference signal or other nuisance transmission. In terms of maintaining up to date user access, managing profiles is a quick process so as new staff come on board or others are departed, this can be updated easily and kept up to date- this way you dont have ex employees running around wit haccess to your network.
