Whilst BS 5839‑6 has previously been split into six varying Grades, each outlining the level of protection appropriate for certain properties and their corresponding levels of risk, the new update has altered the six sections, removing Grade B and Grade E, whilst Grade D and Grade F have been split into Grade D1 / Grade D2 and Grade F1 / Grade F2 respectively.

Grade C

Grade D2
A system of one or more mains-powered detectors, each with an integral standby supply consisting of a user‑replaceable battery or batteries. (such as FireAngel’s SW1-PF-T and HW1-PF-T alarm).

Extend your protection

Protecting your properties and tenants is easier than ever with our range of smoke, heat, and carbon monoxide alarms. To ensure complete coverage, it’s essential to make sure you’re installing best practice and ensure compliance with your regional fire & CO safety laws.

The free app also allows for easy testing and instant notifications, showing the status of alarms, e.g. if they’ve been removed or need maintenance.
