NOTES:
1) EIA-485: Maximum of 6,000 feet total cable length from FACP to LED-10Ns. Circuit is power-
limited.
2) Up to 32 LED-10Ns may be used on the EIA-485 circuit. The SFP-1024 can power a maximum
of seven LED-10Ns. If additional LED-10Ns are connected, the Notifier FCPS-24 may be used
to supply additional power. (Power supplies used for this purpose must have their negative
terminals commoned together).
3) Between each LED-10N are four wires: A twisted-shielded pair for data communications and a
pair for 24 VDC power.
Figure 1-4: Typical Configuration
Table 1-1: LED-10N Addressing
Typical Configuration
The LED-10N indicates the status of the SFP-1024, while offering multiple annunciator
locations with the capability of remote Acknowledge, Signal Silence, Drill and Reset
functions. The LED-10N displays zone status and requires no programming.
