Here is an Aico Ei161RC for sale! This was part of a lot of other smoke alarms, has been tested throughly and sounder, mains, sensor and backup battery all works, but selling for parts as it’s expired (July 2024). This could be good for collectors or a temporary install. Easi-Fit base is NOT included, head only, alarm will need a base in order to power on. Thanks for looking!
