11 SPIROGUIDE ELECTRONICS CONFIGURATION AND PASS DATA
LOGGING
The S9 SpiroGuide electronic system has standard default settings for the BAC
and DDU.Optional settings, depending on the preference of the Fire Department,
are available and can be set by an Interspiro certied service technician using the
InMode program while the BAC is placed in the “Service mode”. A separate InMode
User manual describes how the Interspiro certied service technician can change the
default conguration settings.
11.1 DEFAULT AND CONFIGURATION OPTIONAL SETTINGS FOR THE BAC
AND DDU
Digital Display Unit (DDU) values
The default settings show four different values in the following order:
Priority 1: Cylinder pressure symbol
Priority 2: Cylinder pressure in psi
Priority 3: Remaining time
Priority 4: Absorbed temperature
The priorities may be set in any different order and any or all of the different values
may be turned OFF. (see section 3.2)
Remaining Time Calculation
The default setting calculates the remaining time from FULL (starting cylinder
pressure at 90%-100% FULL) to the low air alarm warning level. The Remaining time
calculation optional setting is from FULL (starting cylinder pressure at 90%-100% FULL)
to zero (EMPTY) cylinder pressure. (see section 3.2)
Electronic Low Air Warning
The default setting is OFF. A mechanical whistle is the primary audible low air
warning and can not be silenced in the InMode program. The optional electronic low
air warning (audible electronic whistle sound) can be turned ON in the
InMode program. The electronic low air warning also has an optional mutable
function in the InMode program depending on the preference of the Fire Department.
If mutable, the electronic low air warning will be silenced for 10 seconds by pressing
the backlight button on the DDU (see section 3.2 and 6.4)
DDU Turn Back Signal
The default setting is at 50% cylinder pressure (same as the HUD ashing yellow
and red LEDs at 50% cylinder pressure, see section 3.1). The backlight of the DDU is
automatically illuminated in red for 10 seconds at 50% cylinder
pressure which is the “Turn Back signal” to the reghter. (see section 6.4). An
optional Dynamic Turn Back signal can be used depending on the preference of the
Fire Department. The dynamic signal activates at a level automatically calculated by
the SCBA. The level is set halfway between the initial starting pressure and the low air
warning level.
