4.5.3 Change Alarm Mode
There are two different alarm modes in IAQRAE: Auto-Reset
and Latched. In Auto-Reset mode, the alarm automatically
turns off when the alarm condition no longer exists (e.g. the
gas concentration falls below the lower alarm limit). In Latched
mode, the alarm remains on even after the alarm condition no
longer exists. The alarm must be turned off by pressing [Y/+].
1. When the “Change Alarm Mode?” screen appears, press
[Y/+], and the display will show the current alarm mode
selection “Alarm Mode = Latch?”
2. Press [N/-] to toggle between the Latch and Auto-Reset
modes.
3. Press [Y/+] or [MODE] to accept the current displayed
alarm mode and move to the next submenu.
