GFB Deceptor Pro II (part T9504) - Manual

Deceptor Pro II (part # T9504)
Installing and wiring the in-car volume controller
1) Test the unit before installation by connecting the Deceptor Pro II’s plug to the in-car controller. Connect the red
wire to the positive terminal of your car’s battery or a 12V source. Connect the black wire to the negative
terminal. Upon initial power-up, the unit will perform an open/close cycle before reverting to the position
indicated on the controller dial. By turning the dial and watching through one of the valve’s venting outlets, you
will see the inner sleeve move to open or close each of the venting ports alternately, which is how the venting
volume is adjusted.
2) Find a suitable location on or around the dashboard, steering column
or instrument binnacle for your in-car volume controller. Clean both
mating surfaces with Methylated Spirits or similar cleaner and secure
the controller using the supplied double-sided tape. Press hard and
hold the unit for about 30 seconds, and note that it takes up to 24
hours for the tape to develop a strong bond.
3) Using a multi-meter or voltmeter, find a suitable power wire that
reads 12V only when the ignition is turned on. Solder the end of the
volume controller positive (red) wire to the 12V source. It is possible
to use a wire tap or crimp instead, but soldering is the most reliable
joint. Make sure to insulate the joint properly.
4) Find a suitable bolt on the body/chassis and connect the unit’s ground (black) wire to it.
5) At this point you should plug the Deceptor Pro II back into the in-car
volume controller, and test its operation again to ensure the electrical
connections are good. Make sure the unit powers on and off with the
ignition.
6) Unplug the Deceptor Pro II and pass the controller’s extension lead
through the firewall into the engine bay. Often there is an existing
grommet that can be used for this purpose. In any case, it is
important to ensure that the lead is protected where it passes through
the firewall to prevent wear or damage.
Using the In-Car Controller
When powered up the volume dial rim will glow red, and will brighten for easy reading when you make an
adjustment, then automatically dim 3 seconds later to reduce unnecessary glare. The position of the dial is directly
proportional the venting bias - turning the dial fully anti-clockwise sets the valve to 100% recirc, fully clockwise
results in 100% atmosphere venting, and any proportion is possible between these limits.
The controller also features a program button on the rear of the casing. This can be used to limit the range of the
atmosphere-venting bias of the Deceptor Pro II. For example, if you prefer that the maximum atmosphere venting bias
is 50%, you can program the controller so that full travel on the dial gives you only 50% movement at the valve. This
is particularly useful on cars that through experimentation, find that full atmosphere venting does not agree with them.
To use this feature, set the dial in a position that you want as your maximum atmosphere-venting limit, then press and
hold the program button until the dial flashes. The unit will now record this position as the maximum atmosphere-
venting limit. Now when you turn the dial fully clockwise, the Deceptor Pro II will only open as far as the point
which you have just set. For example, if you pushed the button with the dial set in the middle (50% atmosphere
venting), full travel of the dial will now move the valve from full recirc to 50% atmosphere-venting only.
To re-set the controller to allow the full range again, simply turn the dial fully clockwise and hold the button.
