Domestic smoke alarms DG525
BRE (Building Research Establishment) is an independent, research-based consultancy, testing and training organisation, operating in the built environment and associated industries. Domestic smoke alarms (DG525) was written by Emma Warren and published by BRE on 25 May 2012.
UK fire statistics show that you are almost twice as likely to die in a domestic fire where there is no working smoke alarm. Smoke alarms in homes are easy to use, inexpensive and can save lives giving early warning of fire, allowing occupants to safely escape. They are simple, self-contained but often interconnected units, incorporating a smoke detector, power source and alarm sounder. There are two types of domestic smoke alarm in common use: one is fitted with an ionisation smoke detector, the other with an optical or photoelectric detector.
DG525 provides guidance on the types of domestic smoke alarm available, and on their correct specification, location, installation and maintenance. It reviews recommendations in the relevant regulatory guidance and the use of third-party-approved fire detection and alarm products and installers.
It is intended for UK house builders, building control officers, specifiers, manufacturers, building owners and the fire and rescue services. It may also be of use to professionals in other countries.
The contents of the 8 page information paper are:
- Types of smoke alarm.
- Power sources.
- Selecting smoke alarms.
- Specifying fire detection and alarm systems.
- Installation and siting.
