Note (1): These defaults are based upon the results of approval tests in a standard
smoke room.
Note (2): A Rate of Rise setting of zero disables Rate of Rise monitoring.
The approved sensitivity settings for the C7xA and P7xA EWD detectors are as per the table
above.
The P7xA detector can be used in AS1668 systems so long as it has a sensitivity less than
or equal to 10%/m and is not used for Return Air or Spill Air ducts.
The sensitivity settings for the C131A and P131A 130 series smoke detectors are also as
per the table above, but in addition they have an approved range of settings as noted below
(based on AS1603.2 sensitivity classification).
APPROVED SENSITIVITY RANGE

C131A 0.15 to 0.31 MICX 0.39MICX
P131A 5.2 to 9.0%/m NOT PERMISSIBLE
Note that the performance of detectors may be affected by air velocity, temperature, altitude
and applied voltage.
The C7xA and C131A detectors cannot have their sensitivities set greater than 0.99 MICX.
The P7xA detector cannot have its sensitivities set greater than 12.9%/m.
The P131A detector cannot have its sensitivities set greater than 12.0%/m.
The T131A-A and T131A-B detectors cannot have their fixed temperature sensitivities set
greater than 99°C. In addition, the T131A-A cannot have its rate of rise sensitivity set to
greater than 99C/minute.
