Annunciators without system control capability

Have you seen them? The local Walmart used to have a Radionics annunciator by the grocery entrance that lack system control ability. However the annunciator has been replaced and the new one has system control capability.

I’ve seen the occasional Bosch or Radionics keypad that for some reason had hardly any buttons on it (not sure why Bosch/Radionics made such keypads honestly).

Apparently it was done so that people in the public couldn’t tamper with the system functions unauthorized, but the majority of the public are totally clueless about how to even do such.
