Hi Andy, late on watch here. I think with the alarm being coloured it washes it out completely so I've had a go at creating an animated gif of one which I've placed it centre on the page (The orange kneck ties need altering, the yellow colour distracts). Also I initially missed the point that these security fobs were being used in an industrial setting as Daniel seemed to think they are usually used in isolated elderly/infirm folks, so to get around this limitation I've surrounded the fob with photo's trying to stress the many uses.
