Visual fire alarm signals in sanitary accommodation
Where a building has a fire alarm system under Part E, sanitary accommodation must also have visual fire alarm signals in addition to those requirements.
Sanitary accommodation is somewhere people are likely to be in relative isolation. In a building where a fire alarm is provided to comply with Part E any sanitary accommodation should have a visual fire alarm signal in addition to the requirements of Part E.
