See System Status LED on page 40 for a complete
function description.
1. To prevent jamming of signals, wire the
RJ31X jack or RJ38X jack to support line
seizure as shown in Figure 5.
2. Install the jack on the street side of the
phone switch, wired ahead of any PBX
equipment. Line seizure temporarily
interrupts normal phone usage while the
communicator transmits data.
3. Confirm that the panel seizes the line,
acquires dial tone, reports correctly to the
receiver, and releases the phone line to the
in-house phone system.
