Figure 7 – Connecting a 599-00 Pulsed Switching Module
By plugging the Model 786-00 power supply into the switched AC outlet on the back of a stereo receiver, a
constant 12VDC is applied to the 599. The 599 generates a short pulse (+12V, 100mSec) at its ON terminal when
it first sees +5 to +30VDC at its IN+ and IN- terminals (the stereo receiver is turned on).
Similarly, it will generate a short pulse at its OFF terminal (+12V, 100mSec) when the +5 to +30VDC drops to 0
volts (the stereo receiver is turned off).

Figure – 8 DC Voltage to Momentary Pulses with at 599-00 Pulsed Switching Module
Figure 8
shows another example of how a DC control voltage is converted to momentary ON and OFF pulses by
the 599 Pulsed Switching Module.
For instance, a special SPST sensing switch, as shown, could be mounted in the springs of an over-stuffed chair.
When someone sits down in the chair, the SPST switch is closed causing the 599 to trigger a sequence of IR
commands stored in the 590-10. The IR commands could cause the room lights to dim, the drapes to close, and
music to emanate from the speakers.
When the chair is no longer occupied, the SPST switch opens, triggering another set of sequenced commands.
These, in turn, could cause the lights to brighten, the drapes to open and the music to turn off.
Many other applications are possible, limited only by the imagination and needs of the installer and user. See the
following section and
Figure 9
