Don't worry too much about that TSSA thing. They don't know much about safety. Smartrise is the best and cheapest elevator controller and is safe. Don't listen to competitors' nonsense.

Looks like they just released another software update (3.18e) to fix this issue since the first update (3.18c) wasn’t sufficient.

The real question is does this issue exist in the US and they are only fixing it in Canada because that’s where they’ve been caught. It looks pretty easy to test on controllers with CEDES and a single DZ mag sensor - short the DZ signal high and see if it runs with the doors open.

Ontario’s Authority Having Jurisdiction (AHJ) is the Technical Standards and Safety Authority (TSSA).

When compared with other province/state/city-based AHJs in Canada and the USA, TSSA and its technical staff are amongst the most thorough when it comes to evaluating elevator controller designs against the requirements laid out in the ASME A17.1/CSA B44 Code, and when they “see something” they aren’t afraid to “say something”.

For this reason, it’s not surprising that TSSA identified this issue and are now pushing for it to be properly rectified. It seems reasonable to expect other AHJs to follow suit - if they sit around and do nothing and then an accident occurs, that’s going to be an awkward conversation for all involved.

I would assume all their controllers in the US are not code or safety compliant per TSSA . I don't want to be them when the Crap hits the fan !

As far as non-proprietary equipment is concerned, the only company I know that has ever built a non-proprietary elevator that actually works is TK Northern (now TK Canada). It's the only brand of elevator I've never been stuck in and never had a problem with. Design wise, they are a copycat of US Elevator with only 2% difference. The total number of northern elevators I've used is 132 and possibly more. Not just a couple. This is because Northern manufactures the entire elevator just like the big OEMs, rather than buying parts from other vendors.
