Sequence
Received sequences are processed as follows:
1) The first tone in the sequence must be about the length programmed in
sequence, first tone time
.
2) The remainder of the tones in the sequence must be about the length programmed in the
sequence
,
remainder tone
time
.
3) Intertone times must be about the time programmed in
sequence, intertone time
. This does not apply to N tone
sequences.
4) The first digits must match the precode digits.
5) The number of digits after the precode digits must be at least the number programmed in
sequence
,
number of ID
digits
but not more than two plus this number
6) The sequence is considered emergency if the status digits match as programmed in
emergency, status
digit 1
and
2
.
The reception is considered a match if one status digit is programmed and it matches but two were sent.
7) The sequence is considered
autocall
if the status digits match as programmed in
autocall, status digit
1
and
2.
The
reception is considered a match if one status digit is programmed and it matches but two were sent.
8) If the sequence is not autocall or emergency, it is considered a normal call.
Sequences can be DTMF or N tone with programmable frequencies per digit. The tone timings, precode digit(s) and
number of ID digits can be programmed. Precode digits are recommended because they add to falsing protection and
provide the ability to activate the speaker mute relay.
Programming parameters, sequence:
Sequence, type:
Sets the tone set to receive, DTMF or N tone.
Sequence, first tone time:
Indicates the expected length of the first tone to be received.
Sequence, remainder tone time:
Indicates the expected length of all tones following the first tone.
Sequence, intertone time:
Defines the expected length of the space between received tones.
Sequence, precode digit 1:
Defines the first precode digit. A precode digit is a fixed digit that is always located in the
same place in the sequence.
Sequence, precode digit 2:
Defines the second precode digit. The first digit must be programmed to use the second.
Sequence, precode digit 3:
Defines the third precode digit. The first and second digits must be programmed to use the
third.
Sequence, number of ID digits:
Defines the number of ID digits expected. If more are received, these will be considered
status digits. If fewer are received, the sequence will be rejected.
Sequence, N tone frq 0 - F:
Sets the frequencies of the N tone set. Digit E is fixed as the repeat digit.
