Please excuse my ignorance in this aspect but I hope the pros on here can help. I have a scantronic 9100 which I saved from another property, I am trying to set it up from the install manual, well it does ‘seem’ to work somewhat. I am trying it on the bench with zone/tampers linked out and a PIR connected for testing to entry/exit. I can enable it having set up everything goes from day mode to enabled but does not sound bleeping tone to get to exit, but, if I activate the PIR the alarm sounds and can be stopped by entering the access code. Also when testing the display it only shows 18 should it show 88, when I try and enable the zones it never shows 21 just 1. Sorry if this is obscure or the wrong information but I will attempt to answer and any clarification that is is needed, please excuse my fumblings
