TRU-ALERT Height Sensor

In stock

Catch mistakes before they happen (even when climbers aren’t clipped in). Our harness-based height sensor detects when an unprotected climber reaches an unsafe height.  

When a user climbs higher than ~2.5m without clipping into the auto belay connector, TRU-ALERT emits audio and visual warnings, alerting staff and other users to the potential danger.  

An additional order of at least 5 Reset Remotes is suggested for optimal performance, though more may be needed depending on the size of facilities.

Product Details

Our harness-based height sensor detects when an unprotected climber reaches an unsafe height. 

The TRU-ALERT Height Sensor will also detect slack in the webbing line from the harness during climbing.  

When either scenario is detected – an unprotected climber or excessive slack – and the user is ~2.5m above ground level, the TRU-ALERT Height Sensor activates height warning for 5 seconds. This allows the climber to downclimb to a safe level or correct the slack issue. If the issue is not corrected within 5 seconds, the TRU-ALERT Height Sensor activates a safety alarm until it’s reset. 

The height sensor works best with sequenced connectors, including our TRU-CLIP Connector. It’s also compatible with Belay Mate and Self Belay connectors. 

Every TRU-ALERT order includes: 

  • 1 alarm (30% charged) 
  • 1 of each sequenced connector attachment bracket 
  • 1 hook and loop harness attachment strap 
  • 2 wire wraps 
  • 1 USB-C charging cable 

An additional order of at least 5 Reset Remotes is suggested for optimal performance, though more may be needed depending on the size of facilities.

Common Questions

Looking for a little extra help?
What makes TRUBLUE Auto Belays better than the rest?

TRUBLUE Auto Belays use patented magnetic braking technology, also found in high-speed trains and roller coasters. This provides friction-free, reliable braking that eliminates brake pads and reduces wear and maintenance.

Each device undergoes extensive third-party testing by an ISO 17025 accredited lab, ensuring top-tier safety and performance. This results in an extended device lifespan and higher cycle capacity, making TRUBLUE the safest, most durable auto belay on the market.

Why does my TRUBLUE Auto Belay need to be serviced?

TRUBLUE Auto Belays are life-safety devices, and annual service inspections are crucial to maintaining safety standards and ensuring your device warranty remains valid. Lives are quite literally on the line!

Each service includes a comprehensive 62-point inspection, repairs or replacements of worn parts (including webbing), cleaning, and testing across a full range of weights to ensure optimal performance.

How often do I need to service my TRUBLUE Auto Belay?

TRUBLUE Auto Belays require service inspections 15 months after the manufacturing date and every 12 months thereafter to ensure a high standard of performance and safety.

We offer two service options: a standard annual service appointment, where you send in your device for inspection and get the same one back, or contact us for our No Delay Belay program, which provides a quick swap for a recertified fleet device with zero downtime, as well as other benefits.
