About Long Range Radio
If output to Long Range Radio (LRR) is selected, all messages that are programmed to go to
the primary telephone line receiver are also sent to any LRR that can operate in ECP mode.
These messages (by telephone or radio) are sent in Contact ID format (not affected by entry
in field
✱
46).

For UL installations, Long Range Radio must be disabled (✱29 = 0).
The data line is supervised, as well as certain functions in the radio. If communication is lost
or a trouble develops, an attempt is made to send a message via both radio and telephone to
the Central Station.
For complete information, see the manual that accompanies the radio.
