Chapter 4: Reports
166 P/N 3102352-EN • REV 005 • ISS 28DEC18
The report can be used to identify devices with intermittent communication faults. A device
appearing in this report is an indication that the wiring to the device is suspect. To investigate
problem devices, inspect the wiring between the problem device and another device not in the
report. Inspect this section of wiring for problems such as loose connections and intermittent
wiring breaks.
Note: The current hour retries can be cleared and updated by running the Loop Comm Check
diagnostic. (See “Loop comm check” on page 172 for more information.)
Response Quality report
This report lists the devices that are communicating at or below a quality percentage that you
specify. By entering different percentages, you can troubleshoot device communications on a
loop.
The panel periodically stores the measurement of the response for individual devices during
communication polling. The report displays the result of the latest poll as a percentage, where
100% is the best response (maximum possible pulse strength) and anything less than 44%
means that the device failed a communication poll and could potentially generate a
communication fault.
Devices appearing in this report are an indication that the wiring to the devices is questionable
or that the devices themselves are questionable. To investigate problem devices, inspect the
wiring between the problem device and another device not in the report. Inspect the wiring for
problems such as exceeding wiring specifications (see “Addressable device loop wiring” on
page 12 for more information), loose connections, and intermittent wiring breaks and shorts.
To view a Comm Retries diagnostic report:
1. Press the menu button and choose Reports.
2. Choose Diagnostics.
3. Choose Comm Retries.
To view a Response Quality diagnostic report:
1. Press the Menu button and choose Reports.
2. Choose Diagnostics.
3. Choose Response Quality.
4. Enter the quality percentage (0 to 100).
This is a communication percentage value that is used to display the device’s minimum
recorded pulse strength percentage. Enter “80” to list devices that are communicating up to
80 percent of their maximum pulse strength. Enter “50” to list devices that are
communicating up to 50 percent of their maximum pulse strength (devices communicating
better than 50% are not included in the report).
