Wiring Tilt Sensor

This blog post will give you the details to wiring a tilt sensor to your Infinitybox system.  Our system has very powerful security and immobilizer functions.  When you add inLINK to your 20-Circuit Kit, you get piece of mind built into your car’s electrical system.  We’ve blogged about the power of our security system previously.  You can read that at this link.  For an added level of security, you can wire a tilt sensor to your system.  This will trigger an alarm if someone tries to tow your car when you have inLINK security enabled.

You can set any MASTERCELL input to be an alarm trigger.  Most commonly, customers elect to use the inputs for the door pin switches to also act as alarm triggers.  Your horn will honk if someone opens a door when you have security enabled from the inLINK key fob.  You can also use any MASTERCELL input and wire that to a tilt-sensor.  Most tilt-sensors close their contacts when the angle of the vehicle exceeds a set threshold.  This would trigger when someone tries to tow the car or if they shake it.  The most popular tilt sensor that we’ve seen is the DEI 507M sensor.

This sensor is smart.  When you turn off the ignition, if learns the angle of the car.  If you parked on a hill, it knows how much the car can move before it will trigger the alarm.  To make this work correctly, you need to add a relay to the 507M module that grounds a signal wire when the ignition is turned off.  This diagram will show you the details.

Once you have the relay installed, you will need to wire the blue wire in the 507M harness to the MASTERCELL input that you’ve chosen to be your alarm trigger.  You’ll need to work with our application engineering team to get this set up for your system.

Our inLINK Wireless Control Accessory is our most popular add-on to our 20-Circuit Kit.  It gets you powerful control of your car’s electrical features through a simple 4-button key fob.  The inLINK accessory comes with a small radio receiver that gets installed inside your MASTERCELL.  There is no external box that you need to make inLINK work.  We recently published this video that shows you the details of inLINK and what it can do for your car or truck wired with our Infinitybox system.  Check it out here.

We received a great question from a potential customer. He was looking to add the Infinitybox inLINK wireless upgrade to his system and wanted to know how secure it was.

inLINK is a great option for your Infinitybox kit because it easily adds remote control to your wiring system. You get our inLINK radio module and two key fobs. The radio module easily installs in the MASTERCELL.  If you purchase inLINK with your kit, we pre-install it for you. If you purchase it later, it is very easy to install yourself. It is completely plug & play with no software required.  This link will take you to the instructions to install inLINK in your MASTERCELL.

You can use your Infinitybox inLINK key fobs to control many things including your lighting, popping your doors and expressing-down your windows.  Most importantly, inLINK gets you security and alarm functions. When you press the lock button on the inLINK key fob, Infinitybox completely disables the inputs for the ignition, starter and fuel pump. This is done from within the MASTERCELL so it is very secure. If you try to start the car when Infinitybox security is on, you get a clear message on the inSIGHT LCD module alerting you that the car cannot be started. Additionally, you can tie MASTERCELL inputs to switches in your car so that if they are triggered when security is on, you can sound the horn or an external siren. This makes inLINK a very powerful vehicle immobilizer and alarm that is built right into Infinitybox with no additional wiring required.

Since inLINK is the key to the vehicle’s security, the question about the wireless encryption is important. We use Microchip’s KEELOQ hardware and encryption technology for inLINK. This is the exact same technology used in OEM remote entry systems, vehicle alarms, highway toll collection, garage door openers and medical device monitoring.

KEELOQ uses a frequency hopping, 64-bit code system. There are over 4-billion code combinations and every time you press a button, the system randomly generates a new code. The hardware is designed never to react to the same code twice. If you could try each of the different code combinations, it would take you 17-years to go through all of them.

We have our own seed key that is unique to Infinitybox so that other devices using the same KEELOQ technology cannot link to our system.

The Infinitybox inLINK system uses an industry proven, rock-solid technology to ensure reliable transmissions and hack-proof security.
