Total Fire Detection Coverage

The Ei660i is equipped with dual sensors that work together intelligently to detect both fast flaming fires and slow, smouldering fires, offering broader fire coverage than single-sensor alarms. This capability removes the guesswork when deciding which alarm type to install in different rooms—making it a universal choice for multiple household areas.

Recommended installation areas include:

• Bedrooms – Ideal for detecting slow, smouldering fires caused by fabrics or electronics.

• Living Rooms – Monitors fires that could start from heaters, candles, or devices.

• Lofts – Detects overheating wiring or stored material fires.

• Hallways & Landings – Ensures prompt alerts throughout escape routes.

• Dining Rooms & Common Areas – Monitors areas used frequently by residents.

Smart Diagnostics with AudioLINK+

The AudioLINK+ feature allows real-time access to critical alarm data using a smartphone or tablet. Through the Aico AudioLINK+ app, you can download a detailed health report of the alarm, including:

• Alarm activations

• Battery and sensor status

• Test history

• Event memory log

This functionality is particularly valuable for landlords and housing providers who need to maintain compliance, streamline inspections, and address tenant concerns with full transparency.

Dust Compensation Technology

Conventional smoke alarms can become overly sensitive due to dust accumulation, leading to nuisance alarms. The Ei660i’s dust compensation software monitors air quality and automatically adjusts the alarm’s sensitivity threshold to maintain optimal performance, greatly reducing false alarms in areas prone to airborne dust—such as lofts and older properties.

Example Use Case

In a family home, the Ei660i is installed across multiple rooms. If a slow-burning fire begins in a bedroom due to a faulty charger, or a fast-spreading kitchen fire is detected by the heat sensor, the alarm responds immediately. The homeowner can also use the AudioLINK+ app to retrieve a report for insurance purposes or safety audits—without uninstalling the device.

Its wire-free design makes it especially suitable for homes without mains-powered alarm wiring, offering professional-grade protection with hassle-free setup.

The Aico Ei660i Multi-Sensor Fire Alarm (SKU: Ei660i) delivers a high standard of domestic fire detection with intelligent dual-sensor technology, smart diagnostics, and a long-lasting battery. Whether you're upgrading an existing system or installing in a new property, the Ei660i is a compact, compliant, and powerful solution for modern home safety.
