Mode of Operation Input Output Code
Normal operation 1234 1234 Digit 1, Digit 2, Digit 3, Digit 4
Extended first digit 1234 0334 0, (Digit 1 + Digit 2), Digit 3, Digit 4
Extended second digit 1234 0154 0, Digit 1, (Digit 2 + Digit 3), Digit 4
Extended third digit 1234 0127 0, Digit 1, Digit 2, (Digit 3 + Digit 4)
Code Format
For unique alarm codes, each digit can be any value
between 0 and 9.
For extended digits, the two added digits may be any
values that, when added, equal the desired value.
If the sum of two digits is greater than 15, use a value of 15.
For a zero, insert a pause in the tone sequence.

INTERNAL WIRING
The CDR-3 provides two relay
jumpers: JP1 and JP2. JP1 sets
Bell Code relay contacts to
either normally open (NO) or
normally closed (NC). JP2 sets
the Temporal relay contacts to
either NO or NC. See Figure 1
for the locations of JP1 and JP2.

*Use power-limited wiring if the source is power-limited. If the source is
nonpower-limited, maintain a space of 1/4 inch from power-limited
wiring. Otherwise, use FPL, FPLP, FPLR, or an equivalent in
accordance with the National Electric Code.

[1] indicates that
the DIP switch
does not apply to
the function.
[2] The On position
configures the
CDR-3 to generate
march tones upon
the receipt of an
alarm signal. The
Off position
configures the
CDR-3 to generate
march tones upon
power-up.
[3] Program the
CDR-3 and the
RS-232 to the
same baud rate.
