Installation Guidelines
Speaker
– Use the largest speaker that can reasonably fit your available space.
For best acoustics, the speaker should be sealed to the floor so that sound
going out the front of the speaker cannot easily get to the back side.
Volume Switch and Access Jack
– Unobtrusive but accessible. Typically in the
floor of tenders and boxcars and on the fuel tanks of diesels. Many
models have removable pieces, doors, etc. where you can mount these
hidden from view.
Mounting the Sound Board
– Make sure that the sound board will not touch
anything metal. Use the foam tape provided; many modelers prefer hook
and loop tape. The sound board may get warm enough to soften hot melt
glue so we do not recommend it; do not use conductive silicon adhesive
either.
Reed Switches
– If you use track magnets
and reed switches to trigger sounds
and effects, keep the reed switches
away from the speaker magnet and
the strong motor magnets. Reed
switches should ride about ¼’’
above rail head and be spaced ½’’
on either side of center. Reed
switches may be mounted with
adhesive, double sided tape or any
other non-magnetic method.
Speed Sensor
– You may need to experiment to get reliable triggering from a
rotating axle with magnets on it. After
mounting the magnets on the axle, hold
the reed switch in various positions and
hook something to the reed so you can
tell when the switch is closed. An ohm
meter with a beeper works great. You can
point the reed switch directly at the
axle/magnets but there will be less
motion tolerance. With the magnets
sweeping the side of the reed switch as
shown a clearance of about 3/16’’ is
usually right. If you are too close you
may get extra closures—one as the
magnet approaches, and one as it leaves.
Mounting Hole Sizes
– ¼” hole for volume
switch and reed switches; 9/32” for access jack. Speaker depends upon
type and location.
