FAQs (5)
Q. Can I upgrade an existing Ei140 series base with a Ei160 series smoke alarm?

Yes, the bases for the Ei140 and Ei160 series are identical units and are interchangeable.

Q. Can I replace an Ei141 alarm with an Ei146 using the Easychange head kit, leaving the base plate in place?

With the Easichange kits you can interchange the heads with the existing bases as all the bases in that series are the same. Using the tool that comes with the Easichange kit makes taking the old head off and putting the new head on quick and easy without the need for an electrician.

Q. Can you advise what the difference is between the Easichange Replacement Kit for the EI 141 Mains Powered Ionisation smoke alarm and the AICO EI 141 Ionisation smoke alarm?

The difference between the Easichange kits and the Aico Ei141 is that the Easichange kit is designed for DIY replacement of mains powered Aico/EI alarms, does not require an electrician and is supplied with a removal tool and all the necessary instructions for a rapid exchange. If you were to replace your alarm with a standard unit you would require an electrician to do this for you.

Q. Do you supply a tool to remove a mains powered smoke alarm from the base to replace the backup battery and the replacement battery required?

Yes, we do sell the Easichange tool separate to the kits. We also sell the 9v lithium longlife batteries required for these alarms.

Q. Will the replacement smoke alarm kit for an Ei141 smoke alarm allow me to just change the head unit leaving the base plate in place?

Yes, the Easichange replacement kits allow you to just change the head of the unit leaving the base plate in place.

It's hard to rate this item. I won't really know how efficient it is until I have an event involving smoke. I can't rate Safelincs' efficiency in dispatching products highly enough, nor the helpfulness of their very well-informed staff.
