Change High Alarm
At the menu for changing the High Alarm setting, “ Set” and “ go” flash in alternation, and both
“HIGH“ and “ALARM” are shown.
Press [Y/+] to enter and change the setting. Press [MODE] to go back to Detection Mode or [N] to
advance to the next menu.
The LCD displays the current value. Change the value if necessary. (LEL value is shown here.)
To change the value:
1.
Press [Y/+] to increase the number and [N/-] to decrease it.
2.
Press [MODE] to advance to the next digit.
3.
After moving to the last digit and making changes, press [MODE]. A question mark (?) is
shown in the display, asking if you want to save the change.
•
Press [Y/+] for yes. The message “dn” means the change is done.
•
Press [N/-] for no. A “no” message means that the change was abandoned.
•
Press [MODE] to return to the first digit.
Note:
Due to certification requirements for the MeshGuard LEL IR, the maximum value you can
set for High Alarm is 60. If you set a value above 60 and try to save it, the display shows “no” and
it does not accept your change, plus it retains the current stored value.
