Central battery systems are a critical element of safety lighting in high utilisation and mission critical applications. The removal of the need to service self-contained batteries, and centrally supply and circuit-monitor lighting adds significant operational and maintenance benefits to building operators.
The adoption of LED luminaires and the upgrading of battery technologies have opened the door to a new class of system offering extensions in rated battery life from four to 10-plus years, with reduced spatial requirement and lower FM and capital costs.
Prolojik has worked with numerous central battery systems in applications ranging from airports to hospitals, and from laboratories to critical infrastructure. The approach can be a fully centralised approach or a distributed central battery approach, but in all cases there are some fundamental operation outcomes which must be achieved.
Any solution needs to also accommodate the demands of modern lighting control. Utilising DALI and DALI-2 is an efficient mechanism to both control and report luminaire performance during a test scenario. The demands of DALI are very different to that when applying IEC62386-202 for testing and monitoring DALI emergency inverters. In essence every light is now an emergency light and needs to be monitored and reported for normal operation during the autonomous test period, whether that is a monthly change-over test or an annual duration test.
Prolojik has developed a series of hardware and software solutions to accompany and enhance the central battery lighting operation. Products like the PL910 which provide a single device solution for:
Prolojik’s Perspective software can readily be configured to support either self-contained or central battery solutions. We have regional standards must also be adhered to with standards such as BS 5266-1:2016 in the UK, where the requirements are for a functional test must be carried out monthly and a 3-hour duration test annually.
Testing can be scheduled within the software for fully automated testing and reporting. Including automated compliance warnings when the system believes the installation is not being monitored as required.
Comprehensive results are generated and stored within the Perspective software system with the ability to also view the results in tabular or floor plan format. Reports can also be exported as PDF (Portable Document Format) for storing off-system.
We can support central battery integration on a variety of platforms including Modular, Plexus and Lightmatrix. For the Lightmatrix, particular considerations need to be accounted for around cable types and connections which we can support you with during the design phase.
