ADS Group designs, installs, tests and certifies emergency lighting to I.S. 3217 across Dublin. The standard requires a monthly functional test and an annual full-duration discharge test, normally three hours, proving every luminaire stays lit for the full period on battery alone. We carry out the annual test and certification, and we can set up the monthly regime so your own staff can run it correctly and log it.
A monthly flick test proves a luminaire comes on. It proves nothing about the battery. Batteries degrade quietly and fail under load, which is why the annual test runs the full rated duration. It is common for a building that passes every monthly test to fail a significant number of fittings on the three-hour test, and that is exactly what the test exists to catch.
Office churn, partition changes and retail fit-outs move doors, corridors and exits without anyone revisiting the lighting design. Emergency lighting covers an escape route, not a floor plate, so once the route changes the coverage is wrong even though every fitting still works. We check the layout against the route in use.
A three-hour discharge test leaves the building on battery, and in a trading premises that has to be planned. We schedule the annual test outside trading hours where the building needs it, and we stage it floor by floor on larger buildings rather than taking the whole site at once.
Full detail on the system types, the standards and the certification process is on the Emergency Lighting page, and everything else we cover in the county is on the Dublin page.
An engineer assesses the site, reviews the existing system and its documentation, and returns a written scope of works.
