Are the Aico Ei alarms with rechargeable Lithium Cells compatible with previous models?
These have been designed to be fully compatible with previous Smoke and Heat Alarm models. Therefore if an old model 150 series mains powered alarm should require replacement, the equivalent model in the new 150 series can be easily and safely installed in it’s place. All Aico Ei140, 150 and 160 series alarms are also fully compatible with each other.
