Performing the response test
1. Exhale into the diffusion port in the oxygen detector’s junction box cover.
NOTE: Once you begin exhaling into the diffusion port, the Span screen “freezes” and
displays each “selected” channel’s lowest reading. This feature enables you to
verify the readings at the Pioneer in addition to the “local” test at the transmitter.
2. Stop exhaling into the diffusion port, then verify that the readings on the voltmeter
decreased from the normal reading (434.4 mV).
NOTE: If the reading(s) does not decrease, calibrate the affected transmitter(s) as
described in the Calibration section of this insert.
If the oxygen reading(s) is below the alarm 1 setpoint when you return to the
normal screen, the Pioneer will initiate the appropriate alarm condition. You can
view the reading(s) of the “selected” channels on the Fresh Air screen.
To display the Fresh Air screen, press the ESCAPE button, next press the UP/YES
button, then press the ENTER button.
3. Remove the voltmeter leads from the amplifier test points.
4. Press the ESCAPE button until the Save screen appears.
