Appendix M
The output may only be a list of CSM-4
or main board signal circuits. The signal
circuits referenced must be zone
coded audibles.
The following table describes how the
Two Stage Control Function works.
TWO STAGE CONTROL FUNCTIONS
Stage 1
Input
Stage 2
Input
Coded Audibles in
Ouput List
False False Silent
True False
Stage 1 Audible Signal
For example: 30 SPM,
steady or zone coding
False True
Stage 2 Audible Signal
For example: 120 SPM,
steady or temporal
True True
Stage 2 Audible Signal
For example: 120 SPM,
steady or temporal
Multiple Two Stage control functions
may be used in a configuration. A
single coded audible may appear on the
output list of more than one Two Stage
control function. Due to the potential
conflict between the functions control-
ling the same coded output, the follow-
ing rule applies to the Two Stage
control function:
 When a coded audible appears on
the output list of more than one
Two Stage control function and
there is a conflict (that is, some
functions indicate Stage 1 and
some functions indicate Stage 2),
then Stage 2 has priority over
Stage 1. As a result, the coded
audibles in question will output
Stage 2 (either 120 SPM, steady,
or temporal, as selected).
NOTE: When zone coding is selected
as the Stage 1 audible output, Stage 2
always has priority over the Stage 1
coding. Once the coded circuit is driven
into Stage 2 by logic, all zone codes will
stop for that circuit no matter what the
minimum rounds are.
NOTE: When an MXLV is used in place
of CSM-4 signaling circuits, the Two
Stage control function is not used. In
the MXLV situation, the same con-
cepts apply to a speaker function that
would apply to the Two Stage control
function.
Two Stage System Flags
There are two system flags associated
with Two Stage alarm: Reset Inhibit
and Two Stage Audible State. Both
of these flags are writable with user-
designed logic. Refer to the following
table for Setting the Two Stage System
Flags.
SETTING THE TWO STAGE SYSTEM FLAGS
When the Reset Inhibit
flag is held:*
Then the Normal Reset
(Red MMB key) is:
True
False
Inhibited
Not Inhibited
*The default value of Reset Inhibit is FALSE if the
system does not require a Reset Inhibit.
If the Two Stage Audible
State flag is held:**
Then the Normal Audible
Silence (Red MKB key) is:
False
True
Inhibited
Not Inhibited
**The default value of Two Stage Audible State is
TRUE if the system does not require a Two Stage
Audible State Inhibit.
