6.8.5 Tone / Pulse Dialing
The original RFC-1 hardware with the mechanical sounding voice only pulse dials. Later models that use the human-
male sounding speech-processor perform tone dialing using the speech-processor. The tones are designed to
compensate for component tolerances. More recent models have a dedicated hardware for generating DTMF tones.
Use of the dedicated tone generator is recommended if hardware supports this feature. This is the factory default
setting on new systems that have appropriate hardware.
The speech-processor generated tones are a workable substitute for a dedicated tone generator in most cases.
There are a few telephone line emulation devices do not accept them. Pulse dialing should work with all POTS lines
and can be used in situations where the imprecise DTMF tones do not work reliably.
Tones generated by speech processor
Tones generated by dedicated hardware
Program the value from the column V1 into memory address 0999 set the dialing method. Tones generated by
dedicated hardware are the preferred option if your hardware supports this option.
6.8.6 Alarm Call Message Duration
When making an alarm call in voice mode the RFC-1 will repeat the alarm message for a predetermined time-period.
This time-period is adjustable. Select the message duration from the table below and program the corresponding V1
at address 1003.
* This is the default setting.
6.8.7 Alarm Call Pause Duration
When making alarm calls in voice mode the RFC-1 will pause between calls to allow an operator to contact the
system. This time-period is adjustable. Select the pause duration from the table below and program the
corresponding V1 at address 1004.
