Superior Fire Detection for Smouldering Fires

The Ei650iRF is specifically engineered to detect slow-developing fires that release smoke before flame, such as electrical fires behind appliances or fires originating in soft furnishings. Unlike ionisation alarms, this optical sensor is less sensitive to cooking fumes, making it a smarter choice for installations near kitchens, such as in hallways or dining rooms.

This makes it ideally suited for:

• Bedrooms – Protect against electrical fires from chargers and appliances

• Living Rooms – Detect fires originating from heaters or entertainment units

• Hallways & Landings – Ensure early detection across escape routes

• Dining Rooms – Monitor shared or transitional living spaces

Wireless Interconnectivity with RadioLINK+

The built-in RadioLINK+ module allows the Ei650iRF to communicate with other compatible Aico devices. When one alarm is triggered, all interconnected units will sound, providing whole-home audibility. This is especially important in multi-storey homes or HMO properties where early warning across all areas is critical.

Installation is quick and clean—no cabling required. Devices are House Coded using Aico’s installer tools or SmartLINK app, ensuring secure, synchronised communication across the system.

Real-Time Data Access with AudioLINK+

With Aico’s AudioLINK+ technology, you can easily extract a comprehensive alarm report via smartphone or tablet. Using the alarm’s sound pulses, the AudioLINK+ app provides:

• Alarm activation history

• Sensor and battery status

• Faults or maintenance alerts

• Record of testing activity

This is particularly useful for landlords, property managers, or compliance officers who need up-to-date safety information without removing the alarm.

Dust Compensation for Reduced False Alarms

A key innovation in the Ei650iRF is its dust compensation algorithm, which continuously monitors air quality and adjusts the sensor’s sensitivity accordingly. This prevents false alarms from non-fire-related airborne particles such as dust or pet hair, especially useful in older buildings or high-traffic areas.

Example Use Case

In a three-storey family home, Ei650iRF alarms are installed in the landing, bedrooms, and living room. One evening, a charger malfunctions in a bedroom, producing smouldering smoke. The optical sensor detects the smoke early and triggers the alarm. The signal is transmitted wirelessly to the landing and living room alarms, alerting all occupants. The homeowner later retrieves the alarm’s data via the AudioLINK+ app for recordkeeping and peace of mind.

The Aico Ei650iRF Optical Smoke Alarm (SKU: Ei650iRF) is a compact, compliant, and connected solution offering wireless protection, smart diagnostics, and long-term reliability. Whether you're upgrading an existing setup or installing new safety systems, the Ei650iRF delivers intelligent fire detection without compromise.
