How can I disable my Scantronic 9448+?

I have a small Scantronic 9448+ sytem to protect an outbuilding on my property and need to temporarily disable the system so that I can shift the control panel. The distance of the shift is very short (no more than 4 or 5 inches) and all cables will reach so no re-wiring is required. I have the access code (obviously) and the engineers code (as default) but cannot find a suitable command sequence in the installation guide to enable me to completely power down. Any help or advice that doesn't see me setting the thing off would be really appreciated !
