E-FSA64 and E-FSA250 Technical Reference Manual 9
Edwards Signaling eFSA250 panel:
6.0 A total, 2.5 A max. per circuit at 120/230 VAC 60 Hz input voltage
5.0 A total, 2.5 A max. per circuit at 230 VAC 50 Hz input voltage
• Max. resistance: 26 Ω total
• Max. capacitance: 0.35 µF
• EOLR: 15 kΩ, 1/2 W (P/N EOL-15)
• Synchronization: For NACs wired Class A or Class B, signal synchronization
is supported system-wide (all NAC circuits).
• Ground fault impedance: 0 to 5 kΩ
• Power-limited and supervised
Notes
• On the Edwards Signaling eFSA64 panel, Class A wiring is available only
when the optional SA-CLA expansion card is installed. Refer to the SA-CLA
Class A Interface Card Installation Sheet (P/N 3101094) and to the topic “SA-
CLA wiring” on page 23.
• Listed EOLRs must be installed as shown for proper supervision.
• Marking indicates the output signal polarity when the circuit is active. Polarity
reverses when the circuit is not active. Wire notification appliances
accordingly. Notification appliance polarity is shown in the active state.
• Installation limits are subject to acceptance by the AHJ.
