Syphon advice Standard WC Flushvalve Kit With Wave-On Senso

[Tonycane]

Need some advice, have a job coming up where I need to convert a concealed push button cistern to a infrared set up as the tenant has arthritis and can't push the buttons. Can anyone recommend a retro fit kit where I can just change the Syphon and not the whole cistern?

cheers
