27 Appendix B: Wiring The FMC2000 To
External Alarms
The five relays are wired for NO (normally open) and NC
(normally closed) operation.
Read this before wiring a RAEPoint to control external
customized loads.
1. Before wiring a RAEPoint to control external devices,
consult the datasheet that applies to the RAEPoint's relays:

index.jsp#ANCHOR3
2. Some none-resistive loads, such as motors, horns, or
strobes, may present high inrush current, causing relay
contact degradation/welding even they are within the
relays' rating. A simple solution is to place an NTC
thermistor (for example, model B57236S0509M0** from
EPCOS) in series between the relay and the load, to limit
inrush current.
