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)
The table below shows all the units that can interconnect with the EI428 relay.

Q. How can I add an external siren to a Ei radio-frequency smoke alarm system?
A. Use a mains powered RF relay Ei428 to operate a main powered sounder ACY03. The RF relay is capable to pick up the signals of any RF smoke/heat alarm from Ei Electronics/Aico.
