FireAngel FA6620 Optical Battery-Powered Fire/Smoke Alarm

FireAngel FA6620 optical, battery-powered smoke alarm currently priced at £11.98 (was £22.99) — £11.01 off. It’s designed for straightforward home protection and responds quickly to slow‑burning fires that produce thick white smoke.

• Optical sensing chamber "sees" smoke as it enters, giving fast detection of smouldering fires.
• Advanced sensor reduces nuisance alarms from everyday cooking fumes (avoid siting directly in kitchens or bathrooms).
• Fitted with a sealed 10‑year battery, intended to last for the lifetime of the device without battery changes.
• Quiet self‑test function lets you check the unit using a reduced‑sound test button rather than triggering the full‑volume siren.
• Easy ceiling installation with a removable base plate and screws supplied; push‑and‑twist fit. Base plate is compatible with the ST622 for simple replacements.
• Certified to UKCA and BS EN 14604:2005+AC:2008.

Model: FA6620. Current price, certification and features make it a budget option for basic, long‑life smoke detection at home.
