5.9.6. Change Low Alarm
At the Change Low Alarm menu, “Set” and “go” flash in alternation, and “LOW“ and “ALARM” are
visible in the display.
Press [Y/+] to enter and change the setting. Press [MODE] to exit and return to Detection Mode or
[N] to advance to the next menu.
The LCD displays 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 Low Alarm is 60. If you set a value above 60 and try to save it, the MeshGuard LEL IR’s display
shows “no” and it does not accept your change, plus it retains the current stored value.
