The main ranges at a glance
| Aico range | What to check |
|---|---|
| 3000 Series | Mains alarms with rechargeable lithium backup. Models cover smoke, heat, CO and combinations of these sensors. The Ei3000MRF is an optional wireless module. |
| 600 Series | Battery smoke, heat and multi-sensor alarms. Check whether the model includes RadioLINK+; the RF and non-RF versions differ. |
| 140e Series | Mains smoke and heat alarms with replaceable 9V alkaline backup batteries. |
| 200 Series | Battery carbon monoxide alarms. Ei208 is standalone; Ei208WRF includes RadioLINK+. |
| 1000 Series | The Ei1000G Gateway and environmental sensors. Check Gateway requirements and the environmental measurements each sensor provides. |

Check the power and the backup
“Mains powered” does not tell you what kind of backup battery is fitted. The Ei3016 has rechargeable lithium backup, while the Ei146e uses a replaceable 9V alkaline battery. Keep that distinction in mind when comparing maintenance needs. Follow the installation instructions for the exact product.
Check how the system connects
A wireless-capable range can still require a separate accessory. The Ei3000MRF fits compatible 3000 Series alarms and takes power from the alarm head. The Ei650iRF has RadioLINK+ built in. Confirm the connection method and compatibility across the whole system before replacing or adding a device.
Check what comes in the box
Read the listing for the exact model, base, accessories and packaging option. Do not assume a module or other separate accessory is included because the alarm supports it.
Does AudioLINK+ mean the alarm connects wirelessly to other alarms?
No. AudioLINK+ is used to extract alarm data. The standalone Ei208 has AudioLINK+ but cannot interconnect. Wireless interconnection is a separate capability to check. Read the Ei208 specification.
