The Afternoon Scotland Made Simple

Safety,
Reimagined.

Since 2022, every Scottish home must have interlinked smoke alarms - one per storey, one in circulation spaces. Mike's DIY plan: three SM11R4s, factory pre-linked, TÜV Rheinland certified to EN 14604. Screw the brackets, twist-lock the alarms, run one network test. Done by tea time, compliant by law.
