Powerful Dual-Sensor Protection for All Fire Types

The Ei660iRF combines optical smoke and thermistor heat detection into one intelligent alarm. These two sensors constantly monitor their environment and work together through onboard software to accurately identify both slow-smouldering fires and fast-flaming fires. This makes the alarm highly effective across different rooms and risk profiles.

Recommended installation areas:

• Bedrooms – Ideal for early detection of smouldering fires caused by faulty appliances or smoking materials.

• Living Rooms – Monitors for fires caused by heaters, electrics, or open flames.

• Hallways & Landings – Provides audibility throughout escape routes.

• Dining Areas – Adds fire coverage in social zones.

• Lofts – Detects electrical or insulation-related fires in attics.

Seamless Interconnection with RadioLINK+

With RadioLINK+ built-in, the Ei660iRF can wirelessly interconnect with up to 12 other compatible Aico devices. When one alarm is triggered, all alarms sound simultaneously for maximum audibility throughout the property. This is especially important for multi-storey homes, flats, or residential units where early alerts can save lives.

For landlords or housing associations, RadioLINK+ enables remote system configuration and House Coding without accessing each device, simplifying compliance across housing portfolios.

Smart Monitoring with AudioLINK+

Using the AudioLINK+ app, users can extract detailed real-time reports from the alarm via sound pulses. These reports include:

• Alarm activation history

• Battery and sensor status

• Testing records

• RF signal checks

This data is invaluable for compliance auditing, landlord responsibilities, or simply tracking the health of your home’s alarm system over time.

Dust Compensation Reduces False Alarms

The Ei660iRF features intelligent dust compensation technology, which recalibrates the optical sensor to maintain accuracy even in environments with higher airborne particles, such as near vents or older properties. This significantly reduces nuisance alarms while ensuring fast response to actual fires.

Example Use Case: Scalable Safety in a Family Home

A homeowner installs Ei660iRF alarms in the hallway, loft, and living room. If a smouldering fire starts in the loft due to overheated wiring, the alarm triggers and communicates wirelessly to the other units, alerting occupants downstairs. Meanwhile, using the AudioLINK+ app, the homeowner can check when the alarm was triggered and confirm battery status—without removing the unit from the ceiling.

The Aico Ei660iRF Multi-Sensor Fire Alarm (SKU: Ei660iRF) delivers advanced fire detection, wireless interconnectivity, and long-term reliability in one compact unit. Whether for new builds, retrofits, or housing associations, it’s a powerful, low-maintenance solution designed to keep people safe and properties compliant.
