Antenna Cut / Trouble Relay
If the Subscriber does not hear another transmission from any other unit on the
network for more than 1-minute, (as might be the case if the antenna was cut), the
Subscriber begins sending a test message to another unit ID
from its internal routing table. If a Packet Acknowledge is not
received for that test message within the programmed
acknowledgment delay period (default is 1 minute or 60
seconds), a fault condition exists. This fault condition is
annunciated by deactivating relay K1. The relay can be used to
operate a digital dialer, sounder or local annunciation
of the condition. The contacts of the relay are
available at J4.
Max load is 1 Amp at 24 Volts DC, Unsupervised
