One of the other areas where uninterrupted power is critical relates to lifts and smoke extraction within buildings. Our inquiries for this application have increased significantly over the last couple of years, ever since a change in UK legislation which means that all lifts intended for evacuation use must now meet the BS 9999 Annex G (Fire regulations) standard.
Emergency lifts are provided to give priority to the evacuation of individuals who are not permitted to evacuate themselves and disabled persons when stairs are not an option. In the event of a power outage a secondary, independent power supply is required for safety backup such as a Diesel generator and quite often a UPS System.
