Parallel Sensors
This drawing shows how you would use 2 (or more sensors to activate one particular sound.
Example: Using the layout above, Sensor on the left of the station is connected to sound 15 which is the Clickity Clack sound.
Depending on the size of your layout you may want this sound continuous, this means you will need to place another sensor
in the position where the Clickity Clack is about to stop. This will then reactivate the sound. The circuit below is how you do
this, you can add as many sensors to the left of this circuit as you wish.
Reset.
You can connect the RESET to a sensor if you wish. This is socket 16 on the rear. This will reset all sounds that are active at
the time.
Example: You may have a tunnel on your layout, while the train is in the tunnel you may want there to be no sounds. Fitting
a sensor at the entrance will reset all sounds to OFF as the train enters the tunnel.
or
The sounds last too long as the train arrives in the Station, A reset sensor can be placed where you normally stop the train.
Positioning of the Reed Switch
It is important that the reed switch and the magnets are positioned correctly, so that you have clearance as the magnet
passes over the reed switch without hitting it, but not too far above so that the magnet has no influence on the switch. The
ideal clearance is between 2 to 4mm.
Glass Reed Switches
If you are using glass reed switches, please note the following:
Glass reed switches are very fragile. If you need to bend or shorten the
wires you must first grip the wires as close to the glass (without touching
with pliers and bend or cut the wire furthest from the glass. The pliers
will prevent any strain on the glass.
Additionally, if you are soldering onto these wires, hold the wire with
pliers near the glass. The pliers will soak up the heat before it allows the
wire to expand and shatter the glass.
