Precision Heat Detection in High-Risk Areas

The Ei144e is designed to trigger only when high heat is present, making it ideal for:

• Kitchens – Detects real fires without reacting to steam or burnt food

• Garages – Monitors for fires caused by electrical equipment or stored flammable materials

Heat alarms are not sensitive to smoke or fumes, meaning they’re far less likely to cause nuisance alarms in active or utility-heavy spaces.

Easy Installation with Easi-fit Base

The Ei144e comes with Aico’s easi-fit base, streamlining installation for both professionals and DIYers. The alarm simply twists onto the base after wiring, reducing setup time and allowing easy future maintenance or replacement.

Flexible Interconnection Options

The alarm can be hardwired with up to 12 compatible Aico alarms and accessories, or linked wirelessly using Aico’s RadioLINK or RadioLINK+ modules. When one device is triggered, all interconnected alarms sound—providing whole-home awareness, crucial in multi-room or multi-storey homes.

This makes the Ei144e a strong choice for retrofitting older properties or expanding existing fire alarm systems without additional wiring disruption.

Battery and Safety Performance

The unit is powered by mains electricity but includes a replaceable 9V battery to maintain alarm function during power outages. Over its 10-year expected lifespan, the battery will need occasional replacement—alerts are provided when battery power is low.

The thermistor sensor is tested via a button press which simulates high heat, while the unit also conducts automatic self-tests every 40 seconds, beeping if degradation is detected (without triggering the alarm LED).

Example Use Case: Reliable Fire Protection in a Family Kitchen

In a busy household, cooking generates steam and occasional smoke. A standard smoke alarm would frequently false trigger in such an environment. Installing the Ei144e in the kitchen allows for accurate detection of real fire threats—such as oil pan fires or oven malfunctions—while ignoring harmless emissions. The unit can be wirelessly linked to optical alarms in bedrooms and hallways using RadioLINK, ensuring synchronized warnings across the property when danger strikes.

The Aico Ei144e Heat Alarm (SKU: Ei144e) delivers specialist fire protection for high-risk, smoke-heavy rooms. With mains power, battery backup, and interconnectivity, it’s a dependable choice for anyone seeking compliant, low-false-alarm safety in kitchens, garages, and utility spaces.
