I've noticed that both the siren and beep on my Yale wireless 6200 have gone very quiet, I've fitted new Duracell batteries to no avail. It seeems the noise is made by a circular plastic pot screwed into a vented tube. The open end of the pot is closed by a metal plate which appears to be attached internally by a spring. Is this the siren and beeper, and if so should the metal plate be loose. or should it by glued round the edge to the containing pot? If this is the prbolem, would supergluing it make a difference? If not, can one buy a replacement, rather than changing the whole siren box?
