Motionalert™ Alarm; Stealth Mode; Sensor Life Alarm - MSA Altair 5X Mode D'emploi

2.2.3.4 MotionAlert™ Alarm
If MotionAlert is turned ON (+ = ON) (see Section 3.4.2), the instrument
activates a "Man Down" alarm if motion is not detected within 30
seconds. The Alarm LEDs flash, and the horn activates with an
increasing audible frequency. MotionAlert is always turned OFF when
the instrument is turned OFF. It must always be turned ON prior to use.
Access to this feature may be restricted. See Section 3.4.2 for means to
allow/disallow user access.

2.2.3.5 Stealth Mode

Stealth Mode disables the visual, audible and vibrating alarms. MSA
recommends that this feature be left in its default "OFF" state. Stealth
mode can be turned ON through the SETUP - INSTRUMENT OPTIONS
menu (Section 3.4.3).
The message "Alarms OFF" flashes on the monochrome display when
Stealth mode is ON. On the color display, all three alarm icons are
shown as OFF (
)

2.2.3.6 Sensor Life Alarm

The ALTAIR 5X Detector evaluates the condition of the sensors during
Calibration.
As the end of a sensor's life approaches, a warning is provided. While
the sensor is still fully functional, the warning gives the user time to plan
for a replacement sensor to minimize downtime. The Sensor Life
indicator ♥ displays during ongoing operations as a reminder of a
sensor's pending end of life.
When a sensor's end-of-life is reached, sensor calibration will not be
successful, and the user is then alerted by a Sensor Life Alarm.
A flashing Sensor Life indicator ♥ displays during ongoing operations
until the sensor is replaced and/or successfully calibrated.
On the monochrome display, the Sensor Life indicator appears on the
display at the same position as the MotionAlert indicator. If MotionAlert
is enabled (the + indicator displays) and a Sensor Life warning or alarm
occurs, the Sensor Life indicator ♥ takes priority and is shown instead.
On the color display, each displayed gas has its own Sensor Life
indicator. If a sensor is in end-of-life warning, its indicator is an
orange ♥. If a sensor reaches end-of-life, it is in alarm and its Sensor
Life indicator is a continuous blinking red ♥.
See "Calibration" (Section 3.8) for additional details on Sensor Life
determination and indication.
