HELMET INSTALLATION - GENERAL INFORMATION

The ANR module is available to fit "military style" helmets which have an earcup/earseal attached to the inside. The earcups in these helmets are shaped similarly to the David Clark earcup, but are usually about 1/2 inch shallower. These earcups use an earseal which is similar to the standard headset earseal, except that it is slightly larger in diameter. If your helmet does not have earcups with earseals, you will need to purchase these before installing the anr modules in your helmet.

Please call, we now how in stock our new silicone gel helmet earseal @ $29.00/pr.

Installation of the anr modules into helmets will follow the same schematic as shown in the standard instructions (see red, green and black diagram).

We are including two extra grommets & a wiring harness (4-conductor, although you will only need to use 3, use red, black & green) to assist you in the installation. This harness is basically 1 cable which divide into 2 cables. The "2 cable" ends go to the R & L earcups. The "1 cable" end of the harness is where audio+ and 9v+ and common- are attached to the original audio+ and 9v+ and common-.

See the color diagram & instruction booklet.

Any competent tv/radio repair shop or electronic technician can review the schematic and wire the anr modules into the earcups in your helmet. Time to install should not exceed 3 hours.

The quality of the fit of the earseals on your head (how airtight they are) will determine how well the active noise reduction system will perform. For the noise canceling system to work properly, the earcups in your helmet should fit as well as the earcups of the headset. In our standard instructions we state the "gel seal" ear seals are required for use of the anr modules in headsets. We have recently engineered gel earseals for helmet earcups. These earseals are much softer & more comfortable than the original earseals we have found on any helmet. We guarantee you will be satisfied with this earseal & we highly recommend their use.



If you have any doubt about your ability to perform a professional installation, we strongly suggest you take your helmet to a technician or send it to us for a factory installation.
