Technical Specifications for Tyrecheckers Heavy Vehicle LED Alert Caps

  1. The Alert Cap is designed to withstand the toughest of conditions, with the casing made of stainless steel. The Alert Cap is vibration, shock, and “road chemical” resistant.
  2. The Alert Cap is so small (25mm X 14mm) and light (12g) it will have little or no impact on the wheel balancing and is totally water proof and airtight.
  3. The Alert Cap has an accuracy of +/- 2psi.

Battery Life

The battery life has approximately 3-4 years in stand by mode (with correct tyre pressure) or 3 weeks of continuous flashing (with under inflated tyres). The fully integrated batteries cannot be changed.

Precautions

  1. We recommend you periodically check the battery by taking the Alert Cap off to ensure the LED light flashes. A dimming of the flash will indicate a declining battery and the unit should be replaced.
  2. If you run different front and rear tyre pressures, be sure the Alert Caps always remain in their original front/rear positions, since they are calibrated accordingly. To assist you with this you can with a sharp object scratch off the letter “F”(front) or “R”(rear) under the Alert Cap to ensure that it will be reattached to the right axle.
  3. If using Alert Caps in conjunction with valve extensions we recommend you calibrate the Alert Caps on the tyre without the extension before putting them onto the extension.
  4. We do not recommend the Alert Caps for the spare tyre or tyres in storage since normally they would not be visible and the Alert Caps could therefore flash out the battery life without being detected.
