MSA Ultima Series User Manual

(indicated by a flashing alarm display):
• An infrared (IR) remote device (such as the Ultima Calibrator or
Ultima Controller) may be used to reset this alarm.
• If an Ultima/Ultima X Series Gas Monitor has an active latched
alarm, the next IR command it receives from a calibration device
will reset the latched alarm (if it is not beyond the alarm threshold).
The intended IR command will be ignored and interpreted as an
’alarm reset’. When the latching alarm function is inactive, other
valid IR commands may be use.
