Mounting of Panel with ST Electronics
To mount the
ST
panel onto the lift car interior wall surface you need 4 spot-welded
M4 screws in the pitch of 57×122 mm and a sufficiently perforated loudspeaker area
(may be larger than as shown on the figure, yet
in no case may overlap the panel
size
to avoid acoustic short-circuit), a microphone hole and 2 LED holes if necessary.
Mounting drawing for version with 50 mm speaker
4 spot-welded M4 screws on the
panel or lift cabin backside (typically
2 mm thick stainless steel sheet)
Perforated loudspeaker area
Perforation of ST panel itself is shown
here. It is possible to use perforation
prepared for precious version of
panel, but, if perforated area will be
too small or total area of holes is
insufficient, it may reduce a speaker
loudness.
Two LED holes (optional, backlit
pictograms are preferred, located
outside the panel)
Microphone perforation
