Maintenance
Careful installation will also ensure long-term reli-
ability and performance. Remove dust as necessary
from holes. Clean with a soft, damp cloth and mild
soap.
Calibration
Output Calibration
If necessary, the current and voltage outputs can be
calibrated as described previously in the Menu Con-
figuration section by using the buttons and a meter
connected to the output. See the Set-Up section.
CO Calibration
The detector features a precalibrated, replaceable
sensor module. The sensor module can be un-
plugged and a new calibrated module installed in its
place. To swap sensor modules:
1. Disconnect the
device power.
2. Remove the screws
and cover.
3. Unplug the old
sensor module.
4. Install the new
module, ensuring
the module’s
connector is
properly aligned.
5. Reinstall the cover and screws.
6. Reconnect power.
Making adjustments or applying gas to the transmit-
ter is unnecessary using the sensor swap method.
Calibration of sensor modules should be left to expe-
rienced professionals. Calibration with gas requires
an LCD display, a bottle of gas (250 ppm CO in air), a
tank pressure regulator with flow restrictor, and the
necessary tubing with a cap to cover the sensor. KMC
Controls recommends returning sensor modules to
the factory for calibration. Having a spare, compat-
ible SAE-1100 series detector makes the swap easy,
and the spare module can be conveniently returned
to the factory for recalibration.
NOTE: Newer style boards (without LEDs) are
incompatible with older style sensor
modules and vice versa. See Models
section.
