ALTAIR 5X/ALTAIR 5X IR
GB
13
The ALTAIR 5X and ALTAIR 5X IR detectors are available with either a mono-
chrome or colour display.
While the device can detect up to 30 % oxygen in ambient air, it is approved for use
only up to 21 % oxygen.
The alarm levels for the individual gases are factory-set and can be changed
through the device Setup Menu. These changes can also be made through
MSA Link Software. Ensure that the latest version of the MSA Link software has
been downloaded from MSA’s website www.msanet.com.
It is recommended that after making changes using MSA Link software, the device
should be turned off and on.
2.2 Device Hardware Interfaces
Device operation is dialog driven from the display with the aid of the three function
buttons [→ Fig. 1].
The devices have three buttons for user operation. Each button can function as a
"soft key", as defined directly above the button.
Button Definitions
When the button and the button are pressed simultaneously while in normal
measure mode, the Setup mode can be entered after the password is confirmed.
