Data cables to control luminaires are a thing of the past with Eaton’s DualGuard-S central battery emergency lighting system

June 27, 2020

SOEST, GERMANY …  50 years of experience and market leadership have contributed to Eaton’s next-generation, scalable emergency lighting central battery system for medium to large buildings. Completely re-engineered to meet the needs of existing and future regulations, DualGuard-S utilises Eaton’s flexible switching technology to speed up planning, installation and commissioning.

The DualGuard-S central battery system supplies reliable power for emergency luminaires and can be seamlessly integrated into Eaton’s emergency lighting portfolio comprising safety luminaires, escape sign luminaires, low power supply units and automatic luminaire test systems.

On installation, DualGuard-S utilises Eaton’s patented STAR technology, which allows you to commission, monitor and set multiple switching modes on the same circuit, so that no additional luminaire data cable is required. The innovative ACU bus removes the need for duplicate wiring and modules when controlling Eaton luminaires across multiple systems. With the web controller, any changes can be managed through the software rather than physical cabling changes, which reduces both the number of circuits and the costs associated with wiring.

A host of automatic fault detection & monitoring solutions are available, including battery string and optional battery block monitoring, with detailed information on the status of each battery block, including temperature and overall battery health.

On set-up the system looks for the addresses of all luminaires on the system, which can then be named in a pattern that is logical for the building owner and the maintenance team. Any system changes or additions can be easily configured with the auto search function.  All required function and duration tests are automatically scheduled and recorded, simplifying maintenance, service and inspection.

Wireless communication speeds up the set-up of the soft addressable sensors – so no need to glue sensors to the batteries or install a data line, making for much simpler and quicker installation.

In addition to the standard test and monitoring features you would expect from a central battery system, such as automatic logs and automated function and duration testing, DualGuard-S also features:

  • Battery string monitoring for up to 4 battery strings, or optional detailed battery block monitoring on each battery block including voltage and temperature
  • Isolation monitoring and phase monitoring with test button
  • Weak battery indication to avoid damage to remaining cells

DualGuard-S also incorporates addressable charger technology that increases the reliability of the charger and further reduces maintenance costs.

The new range of low power battery block sensors reduces operational complexity through improved monitoring and testing, with the results and messages available via email. The findings can also be viewed through the TFT display or the VisionGuard visualisation software. This level of early warning helps to keep the system in full health and lowers running costs for building owners.

The system is easy to program and edit, right down to luminaire level remotely via the web-enabled, cybersecure interface or via the intuitive colour touchscreen LED display.       

Maintenance managers can then easily set up access permissions via the LED display to prevent unauthorised operation. All essential system information is visible at a glance, via an intuitive menu, available in multiple languages. An integrated web interface is supplied as standard, allowing messages such as power failure, deep discharge protection, charging battery faults, isolation faults, control circuit faults and the device status to be sent to up to 6 email addresses.

"Emergency lighting is present in almost all commercial buildings, which cannot be said for many other technologies, whether it's exit sign luminaires or safety luminaires for illuminating escape routes and other particularly high-risk areas," says Eaton’s Jean Luc Scheer, business leader for Emergency Lighting." The challenge for modern emergency lighting systems is to safely network all functions of an emergency lighting system in order to process project-specific requirements whilst minimising the cost of installation and set-up. Thanks to the new data networking capability of the DualGuard-S platform, we are very well placed."

Cybersecurity checked

Eaton was the first company to be awarded UL test lab status for cybersecurity, and all new Eaton systems and devices with internet access undergo rigorous inspection and testing to ensure they are cybersecure, including vulnerability and penetration testing. Eaton’s is the first emergency lighting web controller to meet the exacting UL cybersecurity standards.

We make peace of mind work.*

With the new DualGuard-S system, consultants backed up by Eaton’s planning, installation and service options can design systems with confidence. For building owners, with one eye on their duty of care and another on their budget, DualGuard-S provides a solution to ensure their costs are controlled whilst occupants have clear guidance on evacuating the building, improving safety for all.

Eaton’s mission is to improve the quality of life and the environment through the use of power management technologies and services. We provide sustainable solutions that help our customers effectively manage electrical, hydraulic and mechanical power – more safely, more efficiently and more reliably. Eaton’s 2019 revenues were $21.4 billion, and we sell products to customers in more than 175 countries. We have approximately 97,000 employees.
