Designed for Maximum Sensitivity, Minimal Disruption

The Ei650i is engineered to detect early-stage fires caused by the slow combustion of materials—such as foam-filled furniture, overloaded sockets, or faulty appliances—before flames develop. Its photoelectric optical chamber identifies visible smoke particles with high accuracy, triggering a powerful 85dB alarm to warn occupants immediately.

Unlike ionisation alarms, the Ei650i is less prone to false alarms from cooking fumes, making it suitable for placement near kitchens in areas like hallways and adjacent living rooms.

Smart Data Access with AudioLINK+

With AudioLINK+ technology, users can extract real-time data from the Ei650i using a smartphone or tablet. The app generates a colour-coded report showing:

• Alarm status and history

• Sensor condition

• Battery life and self-test records

• Event memory and fault logs

This feature is especially useful for landlords, housing associations, or homeowners wanting documentation of alarm function for safety inspections or compliance purposes—without needing to remove the alarm from its mount.

False Alarm Resistance with Dust Compensation

The Ei650i’s advanced dust compensation software constantly monitors the sensor chamber. If airborne dust begins to build up, the system recalibrates the sensitivity threshold to maintain detection accuracy while minimising nuisance alarms. This is essential in homes with pets, old carpets, or areas near windows and vents.

Example Use Case: Reliable Fire Protection in a Family Home

In a two-storey home, Ei650i alarms are installed on the landing, hallway, and living room. One evening, a smouldering fire begins behind the television due to a damaged cable. The optical sensor quickly detects rising smoke particles and triggers the alarm before the fire spreads. The homeowner uses the AudioLINK+ app the next day to check when the alarm activated and confirm sensor status—all without removing the device.

This makes the Ei650i not just a fire detector, but a diagnostic and compliance tool built into a compact, stylish unit.

The Aico Ei650i Optical Battery Smoke Alarm (SKU: Ei650i) is a smart, self-contained fire detection solution, ideal for upgrading home safety with zero wiring. With a 10-year lifespan, dust resistance, and smart diagnostics, it’s the perfect choice for residents, landlords, or property developers seeking reliable, low-maintenance fire protection.
