4.3.2 Wiring the MSR 320
Maximum contact load (resistive load) of the change-over relay:
– 62.5 VA: 0.5 A at 125 V AC
– 30 W: 1 A at 30 V DC
NOTICE! The last detector in a conventional line can be terminated either with a terminal
resistor in the detector base or with an FLM-320-EOL2W EOL module. For terminating the line
according to the EN-54-13 standard, the FLM-320-EOL2W EOL module is required.
