Alarm Condition

If the sensor goes into alarm the sensor data reading starts flashing in red. Also the bold alarm
messages starts flashing on the status bar at the bottom of the screen.

Once the alarm clears the red flashing messages are cleared. However, the sensor location tag
will still be flashing. This feature is useful if any detector went into alarm and then cleared after
sometime. With the tag flashing the user can determine which detector went into alarm state.
This flashing tag can be reset or cleared by pressing the RESET button on the status bar.
