British Standard BS 5839-6:2019 covers specific recommendations for fire alarm systems designed for domestic premises.

Whether you’re a professional or a homeowner, knowing these changes is important. It’s always good to be aware of what standards your alarms should meet, and these changes apply to both new-build and existing properties. The standard contains plenty of detail regarding all aspects of the design and installation of fire alarm systems. One area, in particular, covers the type of alarm to install and what areas of the property need protecting.

The changes to BS 5839-6:2019 includes new grades that cover the different alarm system types. In these changes, Grade C is redefined, Grade D is replaced by D1 and D2, and Grad F is replaced by F1 and F2.

What areas should I protect?

According to the standard, the level of protection to the occupants must directly relate to the risk of fire. However, there are three system categories that describe the level of protection these systems provide. The number of alarms, as well as where they are placed, will affect how quickly a fire is detected. Usually, the higher the system category, the higher the level of protection.

Testing and Maintenance

There is the addition of new Table 3 for testing and servicing by Grade. This is designed for making things clear to read and easier to understand.

Updated Testing Schedule

Aside from Grade A, all systems should be tested on a monthly basis at a minimum. In terms of smoke alarms and any heat alarms, this test may be carried out by the use of a test button. This button will be found on the majority of smoke alarms, heat alarms and multi-sensor alarms. The test should be carried out on every alarm on the premises.

In the event of the fire alarm not having a test button, assistance with testing should be sought from a fire service company. If any alarms are linked, the “one alarm, all alarm” feature must be verified. The alarm should be inspected visually, with any defects being made note of for any action that must be taken.

Carbon Monoxide Alarm Interconnection

Mains powered Carbon Monoxide alarms that conform with BS EN 50291 and installed in compliance with BS EN 50292 may also be connected to the fire detection and alarm system if the manufacturer of the components recommends so.
