How to Disable Texecom Premier Elite 24 Alarm prior to building work

[silverfox2019]

This system has three password / codes. I have the User/ Alarm set-unset code and I have the Master Code. The system was installed professionally and I do not have the Engineer's Code.

Can I / how can I turn off the system for a couple of weeks while we have some building work done.

Any tips gratefully received.
