Standards & law

BS 5839-1

The UK code of practice for fire detection and alarm systems in non-domestic premises, covering design, installation, commissioning and maintenance recommendations.

Check the current edition and amendment before quoting any recommendation.

Fire detection

Cause and effect matrix

The site-specific document mapping every alarm input to its required outputs (sounders, dampers, doors, plant, signalling); the reference for commissioning and testing.

An unversioned or missing matrix is a defect worth reporting in its own right.

Fire detection

Commissioning

The systematic proving of a completed installation against the design: device tests, cause-and-effect verification, sound levels, battery calculations and documentation.

Fire detection

Sound pressure level (SPL)

The measured loudness of the alarm signal at a location; verified during commissioning against the design targets for the premises and confirmed with a meter, not by ear.

Take this with you on the next call-out.

Search fault records by panel, ask the assistant when you are stuck, and use the battery calculator on site. A free account needs no card and includes 5 assistant questions and 20 fault searches a day.
