trouble condition shall be printed. The printout shall include
the type of signal, the circuit or device reporting, the date, and
the time of the occurrence. The printer shall differentiate alarm

buffer to retain the data and it shall be printed when the printer
is restored to service. The printer shall have an indicator to
alert the operator that the paper has run out.

cradle it shall be possible to communicate between five remote
hand sets and the master control station. Hand sets shall be able
to monitor any conversation in progress and join the conversation
