The GDKSS614 created from the 555 timer Mono stable (one shot) circuit.
Our design needed a plus or minus car door triggering voltage so we used a 12v d.c. mini spdt relay
to negative voltage trigger the 555 at pin 2.
The 12v d.c. voltage output to the ignition connect relay 12v d.c. 10 amps from pin 3 is held
off till reset by releasing the one shot button connection.
Logic: open door, mini relay holds on the one shot connection and sends
negative trigger to 555 causing pin 3 to start output (in time) of 12v d.c. spst to ignition relay.
Ignition relay disconnects ignitions' power wire.
Only a hidden switch resets 555 by unholding the one shot button connection
and pin 3 connects ignition power wire.
The two circuits below illustrate using the 555 timer to close a relay for a predetermined
amount of time by pressing a momentary N/O push button. The circuit on the left can be used
for long time periods where the push button can be pressed and released before the end of the
timing period. For shorter periods, a capacitor can be used to isolate the switch so that
only the initial switch closure is seen by the timer input and the switch can remain closed
for an unlimited period without effecting the output.
In the idle state, the output at pin 3 will be at ground and the relay deactivated. The trigger
input (pin 2) is held high by the 100K resistor and both capacitors are discharged. When the
button is closed, the 0.1uF cap will charge through the button and the 100K resistor which
causes the voltage at pin 2 to move low for a few milliseconds. The falling voltage at pin 2
triggers the 555 and starts the timing cycle. The output at pin 3 immediately moves up to near
the supply voltage (about 10.4 volts for a 12 volt supply) and remains at that level until the
22 uF timing capacitor charges to about 2/3 of the supply voltage (about 1 second as shown).
Most 12 volt relays will operate at 10.4 volts, if not, the supply voltage could be raised to
13.5 or so to compensate. The 555 output will supply up to 200mA of current, so the relay could
be replaced with a small lamp, doorbell, or other load that requires less than 200mA. When the
button is released, the 0.1uF capacitor discharges through the 100K and 2K resistors. The diode
across the 100K resistor prevents the voltage at pin 2 from rising above the supply voltage
when the cap discharges. The 2K resistor in series with the 22uF cap limits the discharge
current from pin 7 of the timer. This resistor may not be necessary, but it's a good idea to
limit current when discharging capacitors across switch contacts or transistors.
From Inventors workbook, Shows proper flow of logic for circuit.
Start from Door + Door - input wires. DPDT relay is to constant trigger 555 at rest and when door opens
it will unhold the oneshot then countdown and disconnect ignition power wire.
pressing unit reset opens a reed relay and unlatches the Door + Door - relay so it relaxes and
triggers 555 constantly which connects the ignition power wire.

First I'd like to assure the future of the GDKss614
as related to personal security using "Web cameras"
which I call,ROBO-COP.
Privacy issues and personal security is being lumped
together to form a block to the progress of such
devices.Please consider that privacy is always open
to crime. To be safe,a private person must give
away some privacy to use a body guard or an electronic
We at GDK agree that a camera on everybody will send
a clear message to all that crime cannot ever pay.
The GDK device can turn a "Web camera" on,in the event
that the body exhibits high stress,and such stress
does occure in a crime situation.(more later)Even if thieves
know you have an anti-carjack system in your car
counter measures are ineffective against our systems
because the systems are not installed or used in the same ways
because of accessories like proximty switches,odometer trigs,
vibration trigs,cellphone trigs,reset and valet dual modes,
and fingerprint/stress i.d's on reset and valet switches.
The GDKss614 connects just like a car alarm but is not
a car alarm.
The unique thing about the GDKss614 is the unit needs
no effort on your part during a carjacking.
GDK research has shown that during a carjacking there
is no time to reach for a button to activate a system
so the GDKSS614 was designed to automatically trigger
The activation or trigger is a positive or negative
of 12 volts from the car doors,hidden pressure switch,
and or cellular phone.(Pressure and phone type extra \$$)
The Reset is a hidden push button,voice recognition,and
or key-chain remote controll.(voice,remote extra \$$)
The GDKss614 is built with the environmentalist approved
manufacturing techniques invented by GDK.We use no acids,
leads,rosins,fiberglass etc. yet our electronics is solid
state and repairable,thus allowing GDK to offer life-time
guarantees on the GDK line.(more later)
The GDK EXCLUSIVE VOICE RECOGNIZER RESET SYSTEM,designed
to be used in any language and re-connects your cars
vital function via saying four digits or four words.
The current Anti-carjack units on the market require the
driver to trigger the unit but the GDKss614 is automatic,
so the driver can just leave the scene of the carjacking
quickly and not seem to be resisting the carjacker.
**For our engineers the technical jargon for the GDK devise
is that it is a customized user reset or reset one-shot
combined + or - constant or + or - single pulse activated
adjustable timed current interrupt and or timed interrupt
over-ride and current provider.AC and DC compatable.
The normal state is un-reset with power connected.
The i pin is the input.The f pin is N.O. The c pin is N.C.
Normally Open=Circuit disconnected while un-reset
Normally Closed=Circuit connected while un-reset
GDK is currently using a manufacturing agent to push the
ss614 to new levels of marketing and legislative purpose.
Legislators are being called upon to create a bill making
mandatory all new cars connect to an Anti-carjack
devise.The insurance industry has realized they'r position
in auto security by offering discounts to they'r customers
that install an ss614,and all related fields that benefit
from the devise described at**of which there are over 20,
making the GDKss614 very attractive to corporate sponsors,
private investors,philanthropic individules,and public
inquires,such as you.(more later)
