Replacement for Ei146 and Ei166 Mains Powered Smoke Alarms

Designed to fit perfectly onto an existing Ei (Aico) alarm base, the Hispec Ultimate Retrofit alarms eliminate the need to hire an electrician for installing a different mains-powered alarm system. Effortlessly replace the heads of your current Ei (Aico) mains-powered alarms by removing the old Ei head and sliding the Hispec Ultimate Retrofit alarm into position.
