FAQs
When performing service on a GEM-P1632, GEM-P1664, or GEM-P816, if I do not have the Master Security Code that had been set up when the control panel was initially programmed, it is possible reset the control panel to the default Code without entering Dealer Programming Mode?
If the Master Security Code of the GEM-P1632, GEM-P1664, or GEM-P816 is not known, it will NOT be possible to re-program the control panel. It is not possible to reset the Master Security Code. Therefore, it is extremely important that the Master Security Code is retained when the control panel is initially programmed.
