These systems depend on the integrity of their electrical supplies to operate when required to do so.
This guide provides information about designing power supplies to systems such as sprinkler pumps, smoke control systems and firefighting lifts and draws together the requirements outlined in many product and application specific standards. It takes into account changes to standards that have been made since the first edition (BG 70/2017 ) was published in 2017.

The aim is to increase the safety of building occupants and the fire and rescue services who are required to deal with incidents. Updated standards include BS 8519, republished in 2020, BS 9251, republished in 2021 and BS 9991 which is due in 2021/22.
