What’s the difference between the Wireless Fitting Kit and a Laser Jammer Interface?

Not a lot really. The only difference is that the Wireless Fitting Kit is a complete stand-alone solution for fitting jammers, so it has it’s own little in-car display unit, to give you the jammer alerts. The Laser Jammer Interface links up your jammer with either the C100 or GPSmirror so you don’t need the separate display for inside the car. The alerts are delivered through the Cheetah GPS detector instead. Apart from that, all the other components are exactly the same; wireless transmitter, kill switch, keyfob controller, POWERnode engine running sensor, connector cables, etc.

What laser jammers can be wirelessly linked with the C100?

Cheetah Interfaces are available for the Blinder M27 / M47 series, Blinder M25 / M45 series, Blinder M20 / M40 series, Laser Pro Park, Laser Interceptor *, AntiLaser AL G8, AntiLaser AL G9, Laser Star and Cincinnati Microwave ZR4 (Beltronics and Escort’s laser jammer).

We also still have some kits available on request for older jammer systems like the Lidatek LE30, Target LT400 or the Laser Defender.

* Laser Interceptor Voice Alerts are not supported with our wireless system because the Laser Interceptor voice alerts are not programmed into the firmware of Cheetah GPS detectors. Cheetah’s will give their own voice and tone alerts for jammer and parking sensor alerts.

Is the laser jammer interface legal?

Yes, the Cheetah Interface is legal everywhere. However the actual laser jammer system that you are connecting to may not be legal to use in your state. Laser jammers are legal to use in 40 US states. They are illegal in California, Colorado, Illinois, Minnesota, Nebraska, Oklahoma, South Carolina, Tennessee, Utah, Virginia and Washington DC.

Most European countries ban the use of laser jamming devices. If you drive into a state where the use of laser jammers is illegal, we recommend you make use of the OFF switch.

How do I instal a Laser Jammer with a Cheetah Interface?

The two most difficult things in any jammer instal are; 1. getting the cables through the engine bay firewall to the inside of the car, and 2. finding a safe power supply (especially if you are a novice with car electronics). The Cheetah Laser Jammer Interface overcomes these two problems.

Fitting a jammer is normally quite tricky, even for auto electricians. Basic laser jammers are normally supplied as a bag of components which can be quite daunting to the inexperienced. You have to figure out how all the components go together and it usually means drilling a hole in the dashboard for the basic LED warning light and mounting the buzzer and manual switch. Modern engine bays can be very cramped and it can often be very difficult to get a cable through the bulkhead to the inside of the car, particularly on cars like BMW and Mercedes or larger vehicles like pick-up trucks. Most people don’t know where to even start when it comes to hardwiring and on modern cars it is becoming harder and harder to find an electrical circuit that you can safely hardwire the power from.

If you don’t mind taking several hours doing it yourself or are happy to pay an auto-electrician for a couple of hours of their time then by all means proceed without a Laser Jammer Interface.

However, if you’d rather fit your laser jammer in 10 minutes of your own time, with nobody else knowing your business, or you don’t want unnecessary holes in your dash, or you want to be able to swap the jammer between cars, you should definitely choose the wireless Laser Jammer Interface, because it gets rid of hardwiring problems by connecting directly to the battery terminals to provide a safe instant power supply for your jammer. It eliminates cable run hassles so it makes DIY installation incredibly quick and easy for anyone to do. Finally it eliminates any tell-tale jammer signs from the inside of the vehicle so it’s perfect for installing jammers on leased or company vehicles because you can remove the equipment without a trace.

I already have a laser jammer system installed in my car. Can I still use a Cheetah Interface to get its alerts through a Cheetah c100 or GPSmirror?

Yes, you can retro-fit a Cheetah Interface to your existing installation inside your car. You will not need to use all of the components in the Laser Jammer Interface. Remove the POWERnode engine running sensor. This only works when you connect it directly to a car battery. If you want to continue to use your existing jammer kill switch from the original installation, you should also remove the STEATHnode relay switch and key fob controller. Then simply connect the fuse pack directly to LASERnode transmitter and connect these in-line between your existing kill switch and the jammer system’s control box. This will then transmit your jammer alerts to the C100 or GPSmirror.

Will I be able to switch the jammer off when I want to?

Yes. The default setting of the kit is “power on” so it automatically starts up when you start your engine. The Laser Jammer Interface is supplied with a remote control keyfob kill switch that allows you to switch the jammer off when you reach PSL. You turn the jammer back on with the Keyfob whenever you want to.

The keyfob controls the STEALTHnode relay switch which is connected up between the POWERnode engine running sensor and the LASERnode transmitter.

What alerts will I hear from the C100 or GPSmirror? Does it distinguish jammer alerts and parking sensor alerts?

The Cheetah GPS detectors will alert you with a voice alert, audible tone alerts as well as a discreet flashing LED display. The default voice alert is "Diffuser" followed by a tone alert. You can change the voice alert to say "Laser" using the menu structure of the C100 or GPSmirror.

The detectors distinguish between real jammer alerts, parking sensor alerts, jammer start up tones and jammer reset tones.

Identifying alerts:

  • Real laser jammer alerts – Your display unit will notify you immediately with a continuous voice alert and alarm tone.
  • Parking sensor alerts - The same voice alert and alarm tones are played intermittently, i.e. the same sound is played but there is a pause between the alert tone cycles.
  • Jammer start-up tones - these are always filtered out.*
  • Jammer reset tones – these are always filtered out.

You wouldn’t want a full scale alert every time your jammer powers up or resets, so the Laser Jammer Interface deliberately ignores the tones that your jammer’s buzzer would normally produce at start up*, and also the tones produced by the jammer when it resets after 30 or 60 seconds.

* On Blinder M27 / M47 series jammers, you must disable the start up tones using Blinder’s user software tool.

IMPORTANT NOTE: The parking sensor function on the Blinder M27/M47 is disabled when using the standard Laser Jammer Interface or Wireless Fitting Kit. We can supply a modified Blinder cable that retains the 3-way switch to allow you to retain parking sensor functionality if required.

If I install a 4 head jammer system with the Laser Jammer Interface, does it make the rear jammer heads wireless.

No. The Laser Jammer Interface does not work that way. It does not make the jammer heads themselves wireless. Laser jammer heads don't work on their own as self contained units. They must be connected to their own system’s control box because the control box is the "brains" of the system. It tells the heads what pulse rate to fire to jam any particular laser gun. So with 4 head systems, all the heads must be connected to the jammer control box in order to work. The wireless transmitter then fits to the jammer’s control box, making it wireless so it can be installed more easily in the engine bay and powered safely from the battery.

When I switch the jammer off, the Wireless link LED does not go off instantly. Is my jammer still firing?

No. Pressing the OFF button on the keyfob is the same as turning off the engine. Both instantly cut power to the jammer parts in the engine bay so it’s impossible for the jammer to continue firing. Jamming stops immediately when the power is gone and your speed can instantly be acquired.

The reason there is a small delay in the LED light being switched off is down to the way that all wireless technology works.

When the Laser Jammer is first switched on, the wireless transmitter connected to the jammer system in the engine bay sends out a “Communication Check” signal (CC signal). When the display unit receives this CC signal, it illuminates its wireless link LED – that’s the little satellite dish symbol on the display unit – to show that the system is operating normally, and the wireless connection has been established.

This CC signal is a self test function which is repeated approximately every 20 seconds. Receiving the CC signal tells the display unit to keep the wireless link LED illuminated. If the display unit does not receive a CC Signal for 2 cycles then the display unit will switch OFF the wireless link LED to warn you that the wireless connection has been lost.

In most installations, your display unit will normally be switched on slightly before the wireless transmitter in the engine bay. This means that the display unit is ready to receive the first CC signal as soon as the wireless jammer assembly in the engine bay turns on. This is why the wireless link LED appears very quickly when you start the car. The reason why there is a short delay in the LED turning off when you switch off the jammer is because the display unit is waiting for two missed CC signals before turning off the wireless link LED. It can vary from 21-40 seconds for two CC signal cycles to happen – it depends on where in the cycles you killed the power.

If you switch the display unit on after the engine bay jammer assembly, the display unit will have missed the first CC signal so the wireless link LED will not illuminate until it receives the next CC signal. This can take a maximum of 20 seconds – it depends on when in the CC signal cycle the display unit is switched on.

PLEASE NOTE: THE LASER JAMMER BECOMES FULLY FUNCTIONAL 2 SECONDS AFTER INITIAL POWER ON AND JAMMER ALERTS WILL STILL BE RELAYED INSTANTLY BY THE DISPLAY UNIT EVEN IF THE WIRELESS LINK LIGHT ON THE DISPLAY UNIT IS NOT YET ILLUMINATED UNTIL THE NEXT CC SIGNAL.

I noticed a small flicker on the LEDs in the display unit every 20 seconds or so. What is that?

You may notice a slight flash of the Wireless Link LED on the Cheetah GPS detector whenever the display unit receives a CC signal (Communication Check Signal). This is normal. It is a visible sign of the self test function and it does NOT mean that there is a problem with the Wireless Link.

The CC signal does not interfere with alarm signals being transmitted by the Laser Jammer Interface in any way. So even if you were hit with a laser gun at exactly the same time as the CC signal, you will get the normal alert.

Does it change my jammer’s performance?

No, your jammer has the exact same performance. Essentially all the Laser Jammer Interface is doing is replacing the original piezo buzzer from the jammer’s kit with a new wireless alert system. It doesn’t enhance or impact the jamming performance in any way.

My battery is not in the engine bay. Can I still use your Laser Jammer Interface to make my jammer install wireless?

No problem. You can still use the Laser Jammer Interface to avoid the hassle of cable runs. Simply remove the POWERnode engine running sensor from the assembly. To do this, unclip the POWERnode from between its fuse pack and the STEALTHnode switch, and then just connect the fuse pack directly to the STEALTHnode. Instead of connecting to a battery, you should now hardwire the fuse pack to a switched live power supply in the engine bay. If you are unsure what a switched live supply is, please do not attempt this yourself - consult a qualified auto electrician.

What is the LED on the Cheetah connector cable for?

There is a test status LED to tell you what the laser jammer is doing; receiving power, firing, etc. It operates in exactly the same way as the LED on the original wiring loom supplied by the jammer manufacturer would operate. Please refer to the original jammer’s instruction manual on how their LED will operate and what it will tell you but in general, the LED should flash on red when powered on (and during an alert) then go green to indicate normal status.

I have a Laser Pro Park / AntiLaser AL G8 / G9. Can I still reprogram it when I use a Cheetah Wireless Fitting Kit?

Yes. You will need to remove the buzzer connection temporarily and replace it with the jammer’s original wiring/reprogramming loom that was supplied by the jammer manufacturer. Then follow the reprogramming instructions supplied by your jammer manufacturer. Click here for LPP reprogramming instructions.

When completed, re-insert the Cheetah Interface cable back into the buzzer output.

There is an extra cable coming from the side of the Cheetah transmitter. What is this for?

This is an override cable that connects to a corresponding cable on the side of the transmitter in our Radar Detector Interface. It’s only really ever used in motorcycle installations when both the Radar Detector Interface and a Laser Jammer Interface are mounted in close proximity underneath the motorcycle seat. When these cables are connected, they provide a fail-safe priority override for jammer alerts. If you are not using a Radar Detector Interface, please just ignore this cable.

I have installed my system but there is no wireless link LED showing on the display unit.

Start up your engine and check again for the wireless link to come on. The jammer assembly in your engine bay will only power up when you start your car.

If no wireless link appears after you start the engine, please check all cables are connected joined together to ensure that the LJI is powering up your jammer system.

PLEASE NOTE: the LJI must be connected to the Jammer in two places. It must pass power through to the jammer system and it must take the audio buzzer output from the jammer system, otherwise it will not work.

The jammer alert is going off all the time. What’s wrong?

The Cheetah part of the system will only transmit an alert when the original jammer is giving out an alert. The Cheetah equipment is trying to tell you that there is something wrong with your laser jammer system. Check all cable connections in the Cheetah equipment in your engine bay, then check the laser jammer heads for a bad connection. The likelihood is that some kind of fault has developed in your original jammer system, rather than on the Cheetah equipment.
