Early CO Detection for Safer Homes

The Ei208 uses a high-sensitivity electrochemical sensor that monitors carbon monoxide (CO) levels every four seconds. This makes it an essential addition to homes where gas appliances, oil heaters, or solid fuel burners are present. The built-in pre-alarm LED indication warns users of rising CO levels before they become hazardous, ensuring time for ventilation and evacuation if needed.

Best suited for installation in:

• Bedrooms – Protect sleeping occupants from unnoticed exposure

• Living Rooms – Especially with open fireplaces or stoves

• Kitchens – Where gas ovens and hobs are in use

• Utility Rooms – Next to boilers, water heaters, or gas meters

No Interconnection, Pure Simplicity

Unlike other Aico models such as the Ei208WRF, the Ei208 is not designed to interconnect with other alarms or devices. This makes it a perfect standalone solution for properties or rooms that require independent CO detection without full alarm networking. It is also an excellent choice for caravans, holiday homes, or static homes, where a single-unit solution is often all that's required.

AudioLINK+ – Real-Time Data, Straight from the Alarm

The built-in AudioLINK+ feature transforms this CO alarm into a smart diagnostic tool. Using a free mobile app and the alarm’s sound pulses, users can instantly generate and view reports showing:

• CO alarm activations and durations

• Peak and background CO levels

• Battery and sensor health

• Test logs and historical diagnostics

This is especially useful for landlords, tenants, and safety inspectors who need compliance records and performance assurance without removing the unit from its base.

Example Use Case: Reliable CO Detection in a Family Kitchen

A family installs the Ei208 CO alarm in their kitchen, which contains a gas hob and boiler. One winter morning, a faulty appliance begins emitting CO gas. The alarm detects the buildup, sounds its 85dB warning, and the red LED flashes to indicate the danger. The family evacuates, and the source is addressed. Later, using the AudioLINK+ app, they access a report showing the peak CO level and duration, providing peace of mind and useful information for future prevention.

The Aico Ei208 Battery Carbon Monoxide Alarm (SKU: Ei208) is a simple yet advanced solution for standalone CO protection. With 10-year battery life, AudioLINK+ diagnostics, and certified electrochemical sensing, it's ideal for any home needing effective, no-maintenance CO monitoring with smart functionality.
