I’m curious to hear what makes the Simplex 4100+ your least favorite?

From my experience on these forums, a lot of “hobby” users point the finger at Simplex addressable equipment for being proprietary and generally inaccessible to hobbyists. Unfortunately, this disregards the incredible (in my opinion) capabilities of these systems. ConorTheFAguy6 may have a totally different reason, but that’s my 2 cents for their general reputation around the forums.
With that in mind, for everyone lets be careful of our “brand bashing” rule within the topic, and make sure that all claims against a certain product or manufacturer are based in fact or experience, rather than libel 
.

I haven’t seen any issue so far in this topic, so great job keeping this professional, guys!

Gotta agree with you there - I purchased one of these to mess around with a few months ago, and programming is a very delicate procedure! They seem to be very prone to CPU crashes if a programming option is accidentally skipped or improperly configured - it will freeze the panel until you restart the unit and reprogram that option. Certainly wouldn’t call it the worst tho - now that it’s up and running, I think it’s really cool from a collector’s standpoint!

The reason they are my least favourite panel is because several people have told me (without brand bashing) that they are prone to having CPU malfunctions, even when programmed correctly, they are known for randomly not being able to read addressable devices, again even when programmed correctly, and after about 10 years, the NACS begin to fry and put out more voltage than they are supposed to. The 4020 has the same problem. Please understand that other than those 2 simplex panels, I think the rest of their addressable stuff is amazing and reliable.
