What are the different types of emergency lighting battery technology?
There are a number of different types of battery technologies to be considered when designing an emergency lighting system. The ideal emergency battery technology for each individual site will depend on the size of the facility, its maintenance priorities and accessibility in addition to the projects budget.
Below we have listed the different types of battery technology options available for use in emergency lighting projects.
3-hour Integral Emergency – Manual Check
3-hour integral emergency fittings are continually charged during normal operation and are capable of powering the luminaire for at least 3 hours should the power fail, as required by British standards. This ensures that the occupants have time to exit the building in the event of an evacuation.
Self-Test – Visual check
Self-test is an intelligent emergency luminaire that carries out routine, functional and duration testing in-time with the standards required. This module is a highly cost-effective luminaire option as it eliminates the need for manual testing, alerting faults that require attention through visible flashes and beeps.
DALI Addressable Emergency – Digital Check
DALI Emergency works in a similar way to self-test, with the exception being that the fault reporting is communicated centrally through the DALI system to a PC. This allows the status of emergency fittings to be monitored remotely, negating the need for someone to be on site to view faults. This type of emergency lighting does however have a higher initial cost due to the additional components and wiring required.
With central battery source lighting, the power isn’t generated in every lamp like in self-contained luminaires, but rather from a central location. This central battery system supplies slave emergency safety and escape sign luminaires with reliable power. Because there is only one location to consider, maintenance and route testing is much easier. Furthermore, design life of these batteries tends to be 10 years
This type of emergency lighting is an ideal choice for installations with longevity and low maintenance as priorities, making it common in universities, warehouses, train stations, mills, and a range of high-bay environments
At Hilclare we have over 30-years’ experience supplying a wide range of high-quality, robust, and fully compliant emergency luminaires designed to meet the exacting demands of specifiers, contractors, facilities managers and end users.
Our energy efficient, battery technology options are suitable for a range of applications. They are also fully complaint with the British standards, meeting base design guidelines and those relating to manufacturing, test and use.
