The Ei428 RadioLINK Relay Module is a device that switches a relay upon receipt of an alarm signal from a suitable Ei smoke/heat alarm. The electrically isolated contacts can be used for many applications such as signalling, turning on lights, etc. The Ei428 is designed to operate with all Ei radio-interlinked products (Ei168RC, Ei605 series, Ei407, Ei410 & Ei411, as well as the Ei3100 series)
