The MS-9600 supports up to 636 points and uses LiteSpeed polling, while the MS-9200UDLS is a smaller panel with different electrical requirements. Key differences include the MS-9600's use of filtered NAC power and a wider initiating loop voltage range compared to the MS-9200UDLS (Page 1) [1], [3].
\n\n| Feature | MS-9600 | MS-9200UDLS |\n| :--- | :--- | :--- |\n| NAC Power | Filtered [3] | Full Wave Rectified [3] |\n| Loop Voltage | 16 - 27.5 VDC [3] | 19.05 - 25.18 VDC [3] |\n| Expansion | Supports 2nd SLC loop (Page 1) [1] | Not mentioned in excerpts |\n| Polling | LiteSpeed technology (Page 1) [1] | Not mentioned in excerpts |\n\nThe MS-9600 offers greater expandability and faster polling than the MS-9200UDLS. It also uses filtered NAC power compared to the full wave rectified power of the MS-9200UDLS.
