The updated edition of the UK’s key fire detection and alarm standard, BS 5839-1:2025, came into effect on 30 April 2025. One of the notable updates is the introduction of a recommended label for fire alarm control and indicating equipment (CIE) where the system is connected to the fire and rescue service.
Under BS 5839-1:2025, it is now recommended that a clear notice is displayed on, or directly next to, any fire alarm panel that transmits fire signals to an Alarm Receiving Centre (ARC) or the fire and rescue service.
A typical wording example is:
FALSE ALARM NOTICE
This fire alarm has an active connection to the fire and rescue service.
This update aims to raise user awareness of the system’s signalling pathway and help reduce false alarms — a growing concern for both fire and rescue services and duty holders.
