Overall a good, broadly-based compilation of info supporting the different areas integrators have to navigate. This is especially true for less experienced people looking to learn more, and others involved with physical security and access control/video. However, there are several places that include information related to Div 8 hardware which are misleading, confusing, and at worst incorrect. While I haven't made a detailed review of each of those topics, the sections mentioning fail safe vs fail secure, stairwell doors, REX/PIR applications, paddle devices as exit hardware and hinges definitely fall into one of those three categories where there are some issues. I mention these points genuinely hoping to improve knowledge in the field, so I hope this is received in that spirit.
