Notes
•
Common relay wiring is unsupervised and power-limited
only
when connected to a power-limited source.
•
For common relay wiring, the end-of-
line resistor (EOLR) is determined by the initiating device circuit requirements.
•
Common trouble relay operation does not include AC trouble delay functionality. As such, it cannot be used for reporting AC troubles off
premises. To report AC troubles off premises, use a 3-MODCOM Modem Communicator Module.
