Normal Operation
Once the OnGuard has been installed, configured, and the sensors initialized, it is ready for normal operation. Most of
the time the unit will be in “sleep” mode with no visible sign of activity except a flash from one of the LEDs once a minute.
If the green LED flashes it means the unit is operating properly and no limits have been exceeded. When the unit is
taking a reading, the green LED will flash once per second for about a minute. If there is an alarm condition, the red LED
will flash at a one second “on”, one second “off” rate. At any time, the user can press the ENTER key to wake the unit
and view the current readings or any alarm conditions.
