How does your system work?
Each 510 wireless sensor weighs 23 grams, and each 507 sensor weighs 13 grams, both of which are negligible weights; each sensor screws onto the existing valve stem of each tire monitored while the receiver remains within your view in your vehicle. Each sensor has its own individual code that is easily entered into the monitor. This way, the monitor will only recognize and report data from your sensors and no other vehicle's system. The monitor then highlights a tire and reports tire temperature and pressure. It will rotate around the electronic diagram on the screen and it will report temperature and pressure of each tire monitored approximately every two minutes. The system will immediately focus and report data and alarms will sound and icons will flash on the screen in the event of gradual tire deflation, rapid tire deflation, or elevated tire temperature. 

The sensors transmit tire pressure and tire temperature to the monitor every two minutes unless a gradual tire deflation, rapid tire deflation, or elevated tire temperature event is encountered. In such a circumstance, the reporting is continuous until tire pressure or tire temperature returns to a normal range. 

The system reports in PSI, KPa, Fahrenheit, or Celsius at the discretion of the system owner. The system is accurate to 0.73+/- PSI. 

The sensor operating range of temperature is -40 through 257 degrees Fahrenheit or -40 through 125 degrees centigrade. 

We can take the heat or the cold… Whatever mother nature dishes out, our system will handle! 

Our sensors are operational in heavy rains, snow, high humidity, and wet or icy road conditions. Water in any form is no problem for our sensors. 

The monitor can adhere to a dashboard AC vent using the bracket provided or you can adhere the monitor to your dash board using Velcro to hold it in place. Most users prefer to Velcro the monitor in place. Also, the 507 system includes a specially designed, windshield-mountable, suction-cup mounting bracket. 
How long do the sensor batteries last? 

On average the 510 sensor batteries last between 5 and 7 years and the 507 batteries are intended to be changed approximately every 10-12 months. The sensors stop transmitting after being disconnected from the tires. If you park your commercial vehicle for extended periods of time or if you store an RV for the winter, you can remove the sensors and extend battery life. The included battery life estimate is based upon full time use. 

What happens when sensor batteries do expire? 

As with all wireless systems, when 510 sensor batteries do finally die, you can simply return them to us. For $19.95, we will replace all sensor gaskets, we will replace the shell, we will replace the battery, and we will tender to you a reworked sensor ready for 5+ more years of service. The 507 batteries are intended to be changed approximately every 10-12 months. The 507 sensors operate utilizing a CR1632 battery which is readily available and easy to change. 
How long does the battery in the receiver last? 

The rechargeable Li-ion battery in the receiver lasts several days if left on, or you can leave the receiver plugged in to your cigarette lighter outlet and leave it on continuously. The rechargeable battery allows you to remove the cigarette lighter cord to free up your cigarette lighter outlet while driving.   
Is the display backlit? 

Yes, the display has automatic two-stage backlighting. First, it has a light sensor that only allows the light to come on when it is needed. Second, the receiver has a vibration detector that knows when you are driving, or, more importantly, when you are parked. When parked, even in the dark, it allows the backlight to turn off, but it turns back on when you start driving. 

How do I know if I need a repeater? 

You really won’t for sure until you install the system. One customer needed one for his 45-foot tag-axle motor home because it was dropping sensors on the rear duals and on his toad. This is due to interference within the coach space. 

One customer has a pickup that pulls a 30-foot gooseneck race trailer that did not need a repeater. Interference, not distance, is the major factor in determining whether or not you will need a repeater. 

We do suggest a repeater if you are a commercial freight hauler, if you have a motor home over 38 feet in length, or if you pull a toad or trailer with a motorhome. 

You can always purchase the system first to see if you need a repeater. If you do need one, they are readily in stock and economically priced. 

Do I need special valve stems? 

No, you do not need special valve stems, but you do need commonly available metal valve stems. 

The added weight of the sensor on a rubber valve stem could cause problems that will be avoided by using metal valve stems. 

Most motorhomes and commercial transport vehicles come equipped with metal valve stems. If you do need metal valve stems, they are not expensive; a recent customer had 6 valve stems replaced on a 30’ gooseneck racing trailer for $36. They are available and can be quickly installed by any tire dealer. 

What is the device with the black handle I see in the pictures of your systems? 

Our sensors are theft resistant because the outer sensor shell spins freely on the sensor so that it can not be removed by hand. The sensors must be installed and removed with the black handled wrench you see in the pictures. We include 2 of these wrenches with each system. 

What is a repeater? 

A repeater is basically a device that receives data from your sensors, strengthens the signal, and pushes it forward so that the monitor can receive tire data. There is no programming involved. Simply connect the repeater and it works from that moment on. 

What is involved in installing the repeater? 

It simply direct wires to a 12 volt battery or you can splice it into a 12 volt power supply within your vehicle, commercial truck, or trailer. There is no programming or any other user interaction required. 

Our repeater is fully weatherproof, so it can be mounted anywhere. It is suggested that it be installed as far away from the receiver as possible to get the best range improvement. Some examples of where the repeater can be mounted are: in the engine/battery compartment of a diesel pusher coach, under the hood of your toad vehicle, under the rear of your truck, to the rear of the truck cab, or under a trailer. You can get creative. All you need is a 12 volt power lead and a ground. 

Due to the unlimited mounting options, no fuse is included with our repeater. You should fuse the power lead as close to the power supply as possible. 

Weather resistant fuse kits are available at any auto supply store. A 1 or 2 amp fuse is sufficient. Fuse kits do not come with the repeater because of differing installation locations and wire length needs of our customers. 

If you have questions regarding installation, just call us, and we are happy to walk you through this process. 

Are your 507, Standard or Flow Through Sensors compatible with the 510 system?

The 510 system operates using four digit alpha numeric sensor codes, where as, the 507 standard and flow through sensors operate using a six digit alpha numeric code.  For this reason, these systems are not compatible.  We do offer a discount for any of our existing customers seeking to upgrade their systems to 507RV.  Send us an email and we will contact you.
