SYSTEM COMPONENTS
Device Key
The TPMS Module receives 433 MHz tire-sensor data and sends information to the TireMinder app using Bluetooth. The mount supplies constant 12/24 V DC power.
INSTALLATION
Installing the TPMS Module and Mount
Note: Two sets of self-tapping screws are supplied: one for wood, plastic, or composite surfaces and one for metal surfaces. Ensure the proper type of screws are used to secure the TPMS Module Mount.
Step 1 — Determine Where to Mount the Module
Mount on the trailer frame of a utility or boat trailer; on the exterior trailer wall for gooseneck and horse trailers; or inside the front storage compartment of a travel trailer or fifth wheel. For an aluminum-body trailer, mount on the frame or exterior wall. In a motorized RV, mount between the front steering axle and rear axle.
Recommended range: No farther than 35 ft from the farthest rear axle and no farther than 60 ft from the towing vehicle cab. An additional signal booster may be used when more range is needed.
Step 2 — Mount and Wire the Module
⚠ WARNING
Turn off trailer power and completely disconnect the battery before continuing.
- Install the mount vertically so the module antennas face upward.
- Attach the mount using the correct screws. Pre-drill with a 3/32 in drill bit. Do not overtighten.
- Connect the red wire to constant 12 V DC power and the black wire to ground. If the trailer has a battery disconnect, connect ahead of the disconnect.
- Restore power and slide the module into the mount. The green power light should illuminate immediately.
Electrical note: Compatible with 12 V and 24 V DC and equipped with under- and over-voltage protection. A fuse is not required; if one is used, use 3 A.
