G.1  Capabilities
When installed with an SFP-1024 Fire Alarm Control Panel (FACP), the LDM annunciator is used to provide an interface to a custom 
graphic annunciator. All releases of SFP-1024 software can support LDM modules, no special software is required. The LDM can be 
assigned to any of the panel annunciation points. 
An LED-10IM Interface Module is required on the SFP-1024 to allow connection of annunciators to the panel. A maximum of 32 
devices can be connected to the EIA-485 output of the LED-10IM Module. 
For more information on annunciator operation and FACP programming under various specific applications, refer to the SFP-1024 doc-
uments referenced in Section 1.3, “Related Documentation”, on page 7.
