WARNING To maintain sensor accuracy
when using the pyrolyzer, perform a gas calibration
every six months. Do not allow the ambient tem-
perature at the point of installation to exceed 40°C
(104°F). Operation above this temperature may require
more frequent bump testing or calibration to confirm
working specification. Because of the higher operat-
ing temperatures when using the pyrolyzer module,
Honeywell Analytics strongly recommends that the
ventilated Midas Top Cover (shown in Diagram 9-1) be
used in all pyrolyzer applications.
Note:
Consult the label on the side of the Pyrolyzer
module, as shown in Diagram 9-7, for the
rmware version level required in the Midas
detector for proper operation.
