Certain manufacturers whose control panels and digital communicators will
transmit the
Radionics BFSK
format offer the option of transmitting expanded
information for
all
Event Codes (i.e.,
0 through 9
and
B through F
). This
enhancement to the original format offers additional information that may be
useful to the Central Station and may better serve the interests of the subscriber.
If the
Radionics BFSK
format is programmed for the subscriber's
equipment, and an option exists to have
expanded
information sent for all
Event Codes,
PARAMETER 61
is used to inform the CP-220A which of the
two versions of the format (
EXTENDED BFSK ALARMS
or
NO
EXTENDED BFSK ALARMS
) is being sent.
NOTE: The terms
Expanded
(in the text) and
Extended
(on the CP-220A)
have identical meanings. See
Appendix B
for additional information
on
Expanded
(Extended) formats.
The CP-220A allocates 5 characters for all incoming transmissions in the
Radionics BFSK
format, regardless of whether or not the messages carry
expanded information. The table below provides several examples of how
messages will be processed by the CP-220A, depending on which of its two
options (
MAY EXTEND BFSK ALARMS
or
NO EXTENDED BFSK
ALARMS
) is selected for
PARAMETER 61.
The letter "A" is used to "pad"
digit positions where no character would otherwise appear. See the
comments below the table for additional clarification.

Comments
:
When
Extended BFSK
alarms
are not
permitted:
Event Codes between 0 and 9
will not
carry, nor will the CP-220A process, extended information; because the
CP-220A allocates 5 positions for all
Radionics BFSK
transmissions, an "A" is used to "pad" the fourth digit
position, and, as such, the "A" can be disregarded. This is illustrated in the 1st, 3rd, and 5th sample events.
When Extended BFSK alarms
are
permitted:
Event Codes between 0 and 9
will
carry extended information, and all 5 positions allocated by the CP-220A for
Radionics BFSK
transmissions will be filled. This is similarly illustrated in the 1st, 3rd, and 5th sample events.
Event Codes Between “B” and “F”:
In
all
cases, Event Codes between
B and F
will carry extended information and will be processed in the same
way, regardless of the option selected in
PARAMETER 61.
This is illustrated in the 2nd and 4th examples.
