Disable IDNET CO Algorithms
Overview The Disable IDNET CO Algorithms is one of the options available under the Diagnostics menu, at the
front panel of the 4010ES. When choosing this option, the technician ensures that the CO sensors will
get a testing threshold downloaded and the CO over time is disabled. With the Disable IDNET CO
Algorithms option on, the technician can then proceed to test the devices with the WalkTest option
Enabled or Disabled. When the Disable IDNET CO Algorithms is entered, a trouble will be
generated. The trouble screen that will appear will look as follows:
Since all three possible sensors (photo, heat and CO) could be tested simultaneously, the LED on the
base will be used to give the technician an indication of the test result. The LED states and their
meanings are as follows:
• LED OFF - No sensors have passed the test.
• LED ON - At least one sensor has passed the test (If testing only one sensor this is the LED state
you'd expect if the test passed).
• LED FLASHING - All sensors for this device have passed the test (Note: This could be 2 or 3
sensors depending on what type of CO combination device is configured. This state will not be
seen if only a single sensor is being tested).
Because the sensors can either be tested one at a time or by combining multiple technologies into a
single test, one can follow two similar approaches to complete the tests. and show the two flowcharts
denoting those approaches.
