You wanna know the worst part?
The installer can connect to your alarm system anytime he likes and alter the programming without you ever knowing using the Pyronix software Insite. There is no visible or audible indication on the alarm system.
I strongly advise you to go to the keypad and press the 'D' key and enter your master/manager code and make sure that the options 'Block UDL Set' and 'Block UDL' are set as yes. As default they are both set as No which allows the installer to do anything he likes with the alarm system with no indication whatsoever. He can also download the log which shows if the system is set or unset. I'm sure you will agree a huge security risk to yourself no matter how highly the installation company is regarded!
Even worse than that if a engineer leaves the company he will still be able to access your alarm system as long as the login details remain the same and he has access to the Insite software!
The crazy thing is if you an engineer attends site to program the system locally just by entering the programming mode will generate a audible alert. If he connects remotely through insite there is no alert!
Engineer on site cannot access your user codes, remotely using insite software he can view all the codes!
