LED-10IM
The LED-10IM Interface Module provides an EIA-485 port to support the LED-10N, AFM
Series and LDM Series annunciators as well as the ACM-8R Remote Relay Module and
is therefore required when connecting these devices to the SFP-1024. The SFP-1024
supervises EIA-485 wiring for open circuits via the LED-10IM Interface Module. The
LED-10IM plugs into connector J6 located in the upper right corner of the SFP-1024
main circuit board.
Install the two supplied standoffs into the FACP main circuit board. Ensure that the
metal standoff is installed in the position indicated in the illustration below. Carefully
align the two connectors and press the LED-10IM module securely into place. Make
certain the pins are properly aligned to prevent bending or breaking of any pins. It is
important that the supplied screw and washer be used to secure the module to the
metal standoff. This is necessary in order to help protect against electrical transients.
Note: Refer to the SFP-1024 Manual Programming Section for information on program-
ming the LED-10N into the system.
