Can’t seem to figure out how to tighten up the slack in the rope. It wants to lock up every time I try to pull on it

This device is not designed to be used as an ascent device. It’s just as hard to pull in slack as it is for the line to run out when descending.

Is there a weight limit to this?

Yes, the max weight limit is 900 pounds.

Can it be used in gear for fire fighters, will iy withstand some heat?

Generally speaking, keeping away from fire is more important! We tested it on 80ft drop at speed of 1ft / s for 3 times, Observed maximum temperature increase was 58deg Fahrenheit, 69F outside temp, 127F the descender temp. From the results, the faster the decline, the higher the temperature. I found nylon and polyester ropes have a melting point about 450F on the technical website, Some information Tom Jones sent stated the maximum usable temperature should be 194F Conclusion: From the data, it seems unlikely Descender can generate enough heat to damage the rope when stopped if the melting point is used but we shouldn't follow this. Using the limit Tom provided on a hot day (100+ F) it probably possible to reach the limit, but you'd have been going very fast. At the same time we do not approve of dropping more than 330ft uninterruptedly Repeat once more: keep the rope away from the fire!

Can you Ascend Freely? Also will it stop you from falling?

It will not ascend with a 12mm rope. It has an anti panic cam that, unfortunately, locks in when you try to ascend. It descends wonderfully, will not ascend on larger rope....if any. Also, it DOES stop completely, with no creep. And I am 225+ gear.
