The Aico Ei3024 is an industry-leading mains-powered fire alarm that combines optical smoke and thermistor heat detection into a single unit. Designed for Grade D1 residential installations, it delivers rapid response times to all fire types—slow-smouldering fires and fast-flaming fires—while dramatically reducing false alarms. Intelligent sensor software continuously adjusts for dust buildup, extending operational lifespan and minimizing nuisance alarms. Operates on 230V AC mains power with a built-in 10-year rechargeable tamper-proof lithium battery backup. Plug in an Ei3000MRF module to enable wireless interconnection across multiple 3000 Series alarms and real-time data extraction via SmartLINK technology. Easy installation and replacement without re-wiring the base plate. Extract real-time alarm diagnostic data (battery status, activations, background noise) directly to your smartphone via the AudioLINK+ app. Large, accessible button to test alarm functions or silence false activations.
