Used on Combat, Supersonic, Nautilus and Aerobatics (maybe others?), these could make three sounds, plus a high score "wail" sound. They may not have been reliable, and do not seem to have been popular with operators. When they failed, they were likely to have been replaced by retro-fitted chime units with a little bit of creative rewiring.
