dallee-electronics diesel sound version 3 wauto horn ユーザーズマニュアル
OVERVIEW: This device is an electronic, self contained, sound system for installation in model
diesel locomotives that are designed to operate with conventional DC track power or other types of
control systems including radio with either track or battery power, also as a stationary sound unit.
Because of its dimensions (2.7" x 0.9" x approx. 0.5" high) the sound system may be limited to
installations in some powered units making the need for use of a "dummy" unit or a trailing car.
This unit differs from the standard DC type sound systems in that it contains automatic Horn play
patterns each time the input is triggered. Triggering the play patterns is done by the use of a reed
switch passing a fixed magnet. The Bell is also triggerd on and off in the same manner. Large
gauge "G" operators usually place the reed switch beneath the locomotive. One side is used for
the Horn, the other side for the Bell. Magnet trips are then placed in the track. Another method of
operation is to operate the sound system as a stationary unit and place the magnets on the
underside of an engine or car.

An on/off switch (not included) must be used to power the sound unit on and off in some
applications. The audio amplifier can produce 1.1 watt of power which is in excess of what most
small speakers can handle. If more audio power is desired, an amplifier such as item #671 or #672
can be used. The speaker impedance must be 8 ohms or higher. Sound volume is adjustable.

Refer to our catalog for available speakers. Always try to use the largest size speaker for the space
allotted or multiple cluster's of four smaller speakers also works well.
Sounds produced via momentary reed switch closure are automated horn patterns, and a bell.
Non-user controllable sounds include periodic air system pressure release, brake release and
diesel prime mover sound automatically adjusted to speed and load conditions.

INSTALLATION INSTRUCTIONS: The sound system consists of a printed circuit board, a
speaker, four 2-pin connectors with wires and one 3-pin connectors with wires. Refer to the
drawing on page 2 to familiarize yourself with the connectors and controls on the sound board.
Then refer to the specific instruction sheets for the type of installation you intend to make. Before

The circuit board should be mounted so that at minimum, the volume control is accessible either
through the frame or via a hatch or a hole in the locomotive body shell. Be certain that the
components on the circuit board do not come in contact with any metal objects as such contact can
destroy the sound system. The speaker should be mounted as per available space bearing in mind
that sound reproduction is enhanced when a speaker is properly enclosed and baffled.

If a DC locomotive is not moving, there is no track power, therefore to have sound it is necessary to
have a separate power supply for the sound system. For in locomotive use, this separate supply is
have a separate power supply for the sound system. For in locomotive use, this separate supply is
a battery. Without a battery, the sound will not work at lower track voltages. For some this is not a
problem. Drawings are supplied for multiple types of connections. If using batteries, we suggest
the use of one 9 volt or 6 AA or 6 AAA batteries in series to maximize volume potential and battery
life. Rechargeable batteries can be used. When connecting the battery (DC) power leads be
absolutely certain that wires connect to the proper DC input leads.

Installation of the reed switches is easily done by making the appropriate wire connections and
placing the reed switch in the proper location for magnet activation. When removing the reed
placing the reed switch in the proper location for magnet activation. When removing the reed
switches, be careful not to crack the glass. Do not bend the leads at the glass ends, use a needle
nose pliers to hold the wire entering the glass and then bend the wire. Bending at the glass will
break or deform the alignment of the reed switch. Carefully solder wires and cut excess lead ends.

Reed switches are not warranted under any circumstance since they are quite fragile and easily
broken physically and electrically. Extra reed switches are available, item 989. After appropriate
lengths of wire are placed on the reed switch, secure the reed switch with either double sided tape
(item 388) or other type of glue. Make sure that all wires to the reed switches and sound system do
not come into contact with any other metal or power wire since this may damage the sound

If any connections are not done properly, especially the power connections, you will damage the
sound system. This type of damage is not covered under any warranty. The sound system is
thoroughly tested and inspected before packing to insure proper function. There is a minimum
charge of $35.00 plus s/h for repair.

SPEAKER MOUNTING: The speaker generally should be mounted so that the sound can actually
"get out" of the locomotive. A hole in the floor or fuel tank is acceptable but open grills or a
doorway may be a better choice as the sound can exit upward rather than down toward the track.

In some cases, particularly with plastic body shells, just mounting the speaker against the shell will
be adequate as the vibrations of the shell can enhance the sound. Enclosing the speaker in a
be adequate as the vibrations of the shell can enhance the sound. Enclosing the speaker in a
chamber will also enhance sound reproduction. A very simple enclosure can be made with a tube.
The longer the tube the better the speaker will reproduce low frequency sound which is inherent in
diesel prime movers. It is usually best to seal the end of the tube, so there are no air passages to
the rear of the speaker, thus creating a sound chamber. By carefully sealing all openings it may be
possible to use the entire body shell as a sound chamber. A simple wall behind the speaker may
be all that is possible or perhaps all that is needed.

Speakers can be attached with double sided tape, with glue or with "hot melt". Enclosures can be
made with plastic, wood, card stock or even metal. Film cans or medicine bottles make excellent
sound chamber enclosures for small diameter speakers. Attachment with "hot melt" is
advantageous as the "hot melt" can be used as a gap filler when creating an enclosure.

A second speaker, wired in series with the main speaker, can also enhance sound quality and will
permit a higher volume without damage to the individual speakers. A tube with a speaker at each
end or a speaker in a doorway at each end of a body shell is an excellent approach. A four
end or a speaker in a doorway at each end of a body shell is an excellent approach. A four
speaker approach will yield the highest volume while still maintaining the 8 ohm minimum
requirement. Drawings for this are included in the speaker instructions.

SOUND INFORMATION:
All sounds are discussed assuming that the sound unit is fully powered at all times. If only
powered from track power, the sounds will only start when sufficient track voltage is obtained.
PRIME MOVER (DIESEL): sounds range from idle to full RPM with eight notches. With no power
to the track / motor the sound system will produce engine idle sounds. As a throttle is advanced to
put the locomotive in motion, a brake release will sound (see below) and the diesel will initially
accelerate to notch #4, and then seek the correct notch setting for locomotive speed. There will be
a distinct volume increase during acceleration.
accelerate to notch #4, and then seek the correct notch setting for locomotive speed. There will be
a distinct volume increase during acceleration.
AIR RELEASE (POPS): Air is pumped continuously in a diesel locomotive to maintain pressure in
the brake system and for other purposes. Periodically the pressure will increase and the excess
will be released through the safety valve. These AIR RELEASE sound (pops) are generated at
the brake system and for other purposes. Periodically the pressure will increase and the excess
will be released through the safety valve. These AIR RELEASE sound (pops) are generated at
random intervals during idle and at all notch settings.
BRAKE RELEASE: sound is produced when the throttle is advanced from the idle position. This
brake release should always precede locomotive movement but will only occur if the diesel sound
is actually at idle. This BRAKE RELEASE has been factory preset but is user adjustable. For DC
brake release should always precede locomotive movement but will only occur if the diesel sound
is actually at idle. This BRAKE RELEASE has been factory preset but is user adjustable. For DC
operators, this requires approximatly 1.5 to 2 volts of input voltage to sense a running mode.
