respirator Capacity
The Bullard Clean Air Box is supplied with up to 8 quick-disconnect fittings. The actual
number of respirators that may be connected to the CAB is dependent on the inlet
pressure to the Bullard air filtration system and the air flow and pressure requirements
of the respirator being worn. Air supply pressure ranges and approved hose lengths for
a respirator can be found in the manufacturer's User Instructions for the respirator.
Air Monitoring
The air flows through the CO monitor and a small amount (~0.5 lpm) is diverted through
a preset internal regulator and flow restrictor, delivering a continuous flow of sample air
to the sensor chamber. The monitor will analyze the air and display the CO concentration
in parts-per-million (ppm). The Green LED located on the outside of the CAB will
illuminate during normal operation when the CO level is below the CO alarm point (10
ppm US and 5 ppm International). If the CO level rises above the alarm set point, the
Red LED on the outside of the CAB will illuminate and an audible alarm will sound.
The red CO alarm and green LED lights indicating normal operation are located on the
face of the monitor inside the CAB15 Clean Air Box.
Function Modes
The knob on the front of the COM10 monitor sets the functions for the CO monitor and
can be switched to RUN, TEST and CAL.

rUn mode is the operation/detection mode. The monitor must be in the RUN mode
to monitor the supplied breathing air. Supplied air must be turned on and flowing to
the instrument while in this mode. When the supplied air is off or interrupted while the
monitor is in the RUN mode, the low flow alarm will sound and LF will be displayed on
the monitor until the supplied air is turned on.
TEST mode allows for bump testing of the sensor or for silencing of the low flow alarm
when supplied air is shut off. To perform a bump test, or zero gas, place the monitor in
the TEST mode and flow the calibration gas into the center of the knob. The reading on
the monitor should be 10 +/- 1 if applying CO gas. The reading on the monitor should
be zero or 1 if applying the Zero gas. In the test mode, the supplied air will not be
monitored and there is no need to turn the supplied air off when entering this mode. Unit
must be zeroed if bump test is performed with 10 ppm CO gas.
CAL mode is the calibration and zero calibration mode. When the monitor is switched
to the CAL mode, the supplied air will not be flowing to the sensor and there is no need
to shut off the supplied air. When in the CAL mode, (AC) AutoCal
Pressing the On/Off button while in this mode will change the display to (AO) AutoZero.
For calibration and zeroing instruction, see the Calibration section.
F1 (fault) is indicated on the display when the cam valve is not positioned securely
in one of these three modes.
Error Codes
rC indicates that the system requires a recalibration.
lb indicates a low battery.
