One of my customers, a landlord of holiday rentals, has asked me if he needs to have his permanently wired mains powered smoke alarm PAT tested. Notwithstanding the 4th Edition being pretty clear on inspection and testing of fixed equipment or appliances (CoP 5.5.1), I have not included smoke alarms before, considering them to be similar to lighting that is part of the Fixed Electrical Installation (ceiling and wall lights). I couldn't reach up that high anyway
I have never heard of one of these causing a fire or any other safety issue but it occurs to me now these devices are mains powered circuit failure could possibly cause overheating. What say you ?
What do other testers think or do regarding smoke and possibly other fire or security type alarms permanently fixed to ceilings and walls ?
