You should first know that we can always provide fans and air circulation systems when it is required by specifications. That said, none of our technology requires ventilation or cooling systems. The reason for this is that ever since our first DMS in 1986, we have made a point not to settle for quick fixes when it comes to signs for our clients. We use exclusively high quality components, managed at low current and installed in our DMS to avoid "hot points". Our power supplies also have their own dedicated fans and do not require additional cooling. All of this forethought and care in design has meant that SESA DMS has always been ventilation-free for easier and cheaper installation and maintenance.
Energy consumption has been one of our primary concerns for years. Because our front face design improves the optical performances of the DMS, our LEDs require less power, which reduces the internal temperature and eliminates the need for ventilation. These factors, combined with highly efficient power supply units, allow our DMS to consume an average of 30% less power than other industry signs while maintaining optimal brightness and visibility.
In short, no! The only important differences between an solar and traditional DMS is the energy chain, which requires virtually no maintenance at all. The batteries are gel, the solar panels are a stand alone system, and the rest of the components are standard electrical equipment, none of which requires special maintenance measures or costs.
Almost any type DMS can be
retrofitted. If you are interested in retrofitting a sign, SESA will conduct a survey to verify if the housing is in good shape and if the front face design matches our display boards. We will never retrofit a DMS if that is not the best technical and economic option for our client.
Yes! Keep in mind, however, that the DMS must be fitted to accommodate the narrower pitch needed for a color display board. Our technician will conduct an evaluation survey for each case to assess feasibility and make a recommendation accordingly.
Of course! We comply with NTCIP v2.39 and our controller can communicate with most US computer systems without any additional configuration.
The newest version of our SCU6 controller has two new features that we are excited to offer you as major improvements to our client sign control experience:
1. The new controller has a color touch screen, allowing for easy and clear manipulation and testing of signs without the need for additional devices or peripherals for input.
2. The SCU6 v3 also makes use of new web server software, allowing clients to perform important tasks from any computer using any web browser. Functionality includes:
- Configuration of main parameters like communication, fault thresholds, etc.
- Maintenance tests and changes such as pixel tests, communication tests, and message alterations
- System back ups to protect from service failures in your main software
Our controllers are configured through an easily navigated web server. No specific software is required and you can access it through any web browser.
Embedded digital I/Os allow you to connect any sensor with a dry contact directly to our controller. This feature could be used to create a system that might, for instance, trigger a specific message when an event occurs such as a heavy truck crossing a low capacity bridge. Outputs can then be used to control gates or other devices in a simple system. In other words, your DMS controller can act as a simple PLC alongside its other functions.
Both DMS use similar technology. The differences lie in the size and housing technology, with the M5000 being the smaller of the two, designed to be mounted on static signs.
We understand it is important to keep brightness level uniform across all LCS installed on a given structure or toll booth. To ensure this, we manage sign brightness through a common light sensor for all units, which are then dimmed or brightened simultaneously. If a dry contact system is used, the LCS will have 3 brightness modes (Day, Night and Over-bright).
Yes we do! Our Smart LCS can be connected either to the SCU6 controller or to a dry contact system. In both cases, you will be able to receive LCS status signals that indicate if each LCS is functioning normally.
