WARNING
The Alarm interfaces and AUX inputs must not be metallically
connected to interfaces which connect to the Outside Plant or its
wiring. These interfaces are designed for use as intra-building
interfaces only. The addition of Primary Protectors is not sufficient
protection in order to connect these interfaces metallically to OSP
wiring.
