BS5839:6 2019 Is Now In Force Quick Tip No. 4

Quick Tip: BS5839:6 2019 Has been updated. There is a new grade, grade D1. This is a system of one or more mains powered smoke, heat or carbon monoxide detectors each with a tamper proof battery. This means the detectors cannot be turned off by removing the battery and or turning off the mains powered supply to them because if the power was to be turned off or fail through a fault on the circuit the battery back-up will keep operating the alarms. Simply the only way to stop the alarm from operating would be to physically remove it from its location.
