One thing to note about security systems... There are generally two distinctly different versions of the same devices... One version is the generic OEM one sold by the company, this is for the DIY consumers or small security installers and includes a manufacture supported firmware that is generally easy to make changes to... Than there is the 'proprietary' firmwares that big security companies flash into these devices making them work only on their own network as to prevent you from using it independently, changes are complicated or impossible without that companies own proprietary software...
If the device was used on a proprietary security network, you would need that companies software... If the device is the OEM software than the company that made it should have software to edit those settings and/or a way to do it from the keypad...
If you search around there 'might' be a firmware flash that will make it more user friendly or steps to unlock certain versions...
