The Function of a Car Alarm

There is a great feeling when you purchase your first vehicle. The feeling of excitement, empowerment, confidence, and freedom are just a few feelings. But owning a vehicle can bring daunting feelings of fear, confusion, or anger if it was ever broken into or stolen. No one wants to wake up in the mild of the night to the blaring alarm from your vehicle, but so many people do. Not every alarm is cause for alarm. Could be a stray cat jumping onto your hood, your neighbor's kids soccer ball hitting the side of your car door, some rude person leaning against your baby, or even a loud noise.
Texas was ranked #2 for the most vehicle thefts in 2017, and that is not good. So it is no surprise that millions of people invest in expensive alarms and lucky us, there are hundreds of choices for us to choose from. But my question is, how does it all work? Basically, it is a couple of sensors connected to a siren and are divided into two categories: OEM and aftermarket. OEM alarms are built into the vehicle at the factory and aftermarket is added security you buy to beef up the security of your car. Fun fact: the earliest version of a car alarm was invented by an automobile mechanic serving time in a Denver jail in 1913.

What It Consist Of

A car alarm consists of a few basic components. The brain/computer, sensors, radio receiver, auxiliary, and siren. The “brain's” job is to close the switches that activate alarm devices. Alarm sensors tell when someone is trying to break into the vehicle. Most common sensors are door, pressure, shock, and motion. The receiver allows wireless control from your key fob. The auxiliary battery is there to keep the alarm going if the main battery becomes disconnected. Sirens bring attention to your vehicle by making a distinct annoying sound. I other words, to make it all work a control unit that processes sensor inputs and triggers the alarm, a handheld transmitter that can arm and disarm the system, and a receiver that provides that information to the control unit.
The FBI reports there were an estimated 765,484 motor vehicle thefts nationwide in 2016. While car theft is still happening and it may be true that we have become kinda desensitized to the annoying sound of the alarm, having and using a car alarm never hurts.

A Few Facts About the Ford Motor Company

Ford Motor Company The Ford Motor Company has seen it all since Henry Ford opened the Ford Motor Company in 1902. From producing vehicles for the public to helping with military equipment, going through some rough times in the past, and to some financial problems. The company has proven to be a brand that plans on sticking around for a long time. Here are a few interesting facts that many have not worked out and some that we still see today. Ford Facts Ford was the first company to manufacture and sell cars. Their first model, the Model A, sold for $850 and only hit a max speed of 30 mph.

While the first Ford was sold in 1903 to Dr. Pfennig (Ford’s current CEO, Jim Hackett, owns it today), the iconic Ford logo was first introduced in 1907. Many may not know that H...

Classic Automobile Features in You Won't See in Modern Cars

Classic Features Classic Features in Cars You Won’t See Today Who knows what kids will reminisce about years from now about their first car. Heck, there’s a chance vehicle won’t run on gasoline anymore, and that is something they will look back on and find nostalgic. Vehicles can start with the push of a button on your keychain, you can open the hatchback with the swipe of your foot, and heated seats (my personal favorite) are just a few features you can find in cars today. Here are a few classic features you won’t see today but were the best. Oldies and Goodies One of my favorites, bench seats. For some reason, I always thought they were fun as a kid, but looking back now, I realize how horrible they really were. Being squished between two adults was actually uncomfortable during long rides. I guess as a kid, you feel the front seat was larger than it really was, and sometimes you had it all to yourself- that’s fun. I’m sure several teenage boys took advantage of the seat design...
