Remote Auto Security & Keyless Entry Systems

Features
- Headlight convenience: this feature allows the customer to turn the vehicle
headlights on to light his path using the remote control transmitter.
- Domelight convenience: this feature turns the dome light on whenever the doors
are unlocked using the remote control transmitter.
- Tamper warning: this feature produces a different unlock confirmation tone if the
vehicle has been disturbed while the driver was away.
- Learning receivers: this allows us to use off the shelf replacement parts for
transmitters because the system has the ability to "learn" and remember the new
transmitter.
- Entry delay warning: during the passive entry delay, the unit gives you an
audible warning before it goes off.
- Warn away: a slight shock to the vehicle produces short warning tones, major
shock or repeated minor shock will produce the full alarm.
- Trunk release: this feature allows the operator to use the remote control to open
the trunk.
- Programmable multi-tone siren: this allows the vehicle owner to recognize his
alarm from others. it also draws attention to the vehicle because of its random and
changing nature.
- Restrained volume chirps: most units have entry and exit chirps which are the
same volume as the full alarm. The SCS/Frigette unit uses chirps that are approximately
one half the volume of the full alarm.
- Anti-Scan: this feature prevents sophisticated thieves from using automatic code
generating devices to randomly scan the system in the hope of hitting the correct code.
With the SCS/Frigette system, if this is attempted the computer monitors the attempt and
after 10 incorrect and different codes are received in under 20 seconds, the system will
shut down for 2 minutes. This makes it virtually impossible to defeat the system in this
manner.
Security History and Background
The decision was made to manufacture auto security systems for several
reasons:
- SCS's electronics expertise and technology in the automotive industry
- The tremendous growth of the auto security industry
- The need for a national company to supply a quality product to the O.E.M. auto
manufacturers and the after market
SCS has devoted several years and in excess of $2,000,000 to develop a
state-of-the-art microcomputer controlled electronic keyless entry/security for automotive
applications. Over 70 competitive systems were analyzed during this development period.
The result is the SCS microcomputer
powered, electronic system. The use of this microcomputer system increases reliability and
allows us to provide you with an abundance of features that otherwise might not be
available. This component is purchased in an extended temperature range which is very
important in an automotive environment. The temperature specifications are -40 to +85 C.
The "watch dog circuit" that we have designed into our keyless entry/security
system monitors the microcomputer as it runs its program. If at any time the microcomputer
fails to run the program in the proper manner, the "watch dog circuit" will
reset the microcomputer and all its parameters back to zero, and it can start its
calculations again.
The auto security industry is now a $1 billion a year business and is
growing at the rate or 15% per year. It represents a tremendous opportunity as a port
installed accessories or dealer installed accessory. This also creates a tremendous profit
opportunity for the O.E.M. auto manufacturers.
We provide O.E.M. line installed, port installed, or dealer installed
keyless entry/security systems to Honda, Isuzu, Jaguar, Mazda, Nissan, and Subaru. The
Jaguar contract is worldwide and in excess of 30,000 keyless entry/security systems per
year. SCS/Frigette supplies Nissan Motor Corporation in the U.S.A. and Canada, remote
keyless entry and remote vehicle keyless entry/security systems. This contract is in
excess of 40,000 units per year. This business is expected to grow rapidly as the
automotive industry recognizes the need for port, dealer, and assembly line installed
keyless entry/security systems.
SCS/Frigette is now in the third generation of our keyless entry/security
system. Even the first system which was introduced in 1987 had features which few if any
other unit had at that time but are now standard for the industry. SCS/Frigette was
granted patents on some of these features, such as "warn away".
SCS systems also takes advantage of the new "EEProm" technology
(not-volatile memory), which will store memory when battery power is disconnected from the
vehicle. This allows several improvements to the old system:
Types of transmitters
1 Button Transmitter
One button can control all function. This is not recommended. 2 Button Transmitter
One button can control all functions except panic and a separate button can be used for
panic. 3 Button Transmitter
One button controls lock, one button controls unlock, one button controls panic. 4 Button
Transmitter
One button controls lock, one button controls unlock, one button controls trunk, one
button for panic.
We now have hardware designs to accommodate vehicles sold throughout the world
utilizing already developed and approved 318 MHZ, 418 MHZ and 433 MHZ frequencies.
We can interface with the vehicles on board diagnostic system.
We have designed systems which have direct communication with the engine
control module. With these systems, it is impossible for the engine to be started if the
system is armed unless it is disarmed with the transmitter.
In the manufacturing side we now have automated assembly capability for
both through hole and surface mounted components.
We have new state-of-the-art soldering machines.
We have designed and built a thermal shock burn-in chamber, which tests
security boards while a computer continuously monitors them to spot even an intermittent
failure.
With all of the above features and manufacturing capabilities SCS/Frigette
can offer the most modern, flexible, reliable and, most importantly, user friendly systems
in the industry.
In 1993 SCS/Frigette tooled new multi-button transmitters. These new
transmitters along with the new microprocessor enable SCS/Frigette to easily duplicate any
control function scheme in the industry.
The new third generation system has already proven itself at Nissan and Jaguar in
volumes exceeding 70,000 units per year. Variations of the system have undergone extensive
reliability, EMI, and EMC testing.
