The door gets opened from a phone, and safety beams never came up
Why it happens
App control is usually added because it is convenient, not because anything is wrong, so nothing prompts a second question. B&D's sectional opener installation manual attaches a condition to it: the opener 'must be fitted with Safety Beams if' the closing force at the bottom edge exceeds 400N (40kg) 'and/or' 'the opener has a smart device fitted to operate the door, when not in line-of-sight'.
Why it matters
Operating a door you cannot see is the exact case that manual singles out. The same manual tells the installer to put the optional wall transmitter 'in a location where the garage door is visible', which is the same principle read from the other direction. It is one manufacturer's instruction for one opener family, not an Australian Standard and not a statement about any other brand.
Response
Deadlock's motor and opener replacement page publishes that a new opener 'usually comes with remotes, and most can be paired to a wall keypad or a phone app so you can open the door without a remote'. If your door is worked that way, say so when you ring 0402 882 653 - it is the kind of detail worth giving before a visit is arranged rather than after.
