NTCIP specifies the same detector diagnostics for ped detectors as for vehicle detectors.  Unless you are in a high pedestrian area, the NoAct (no activity diagnostic) will generate a lot of unwanted errors.  

However, the MaxPres (maximum presence diagnostic) can be very useful to detect "stuck ped buttons".  Just set this value to 3 minutes to mask out a call from a pedestrian holding the button down.  As long as the ped call resets within 3 minutes, you will not get a MaxPres error.

The ErrCnt (erratic count diagnostic) is not as useful for detecting ped button failures as detecting erratic counts from an inductive loop detector. Also keep in mind that many pedestrians will repeatedly activate the pedestrian detector while waiting for a signal change.

 

 

 

 

 

 

 

 

 

 

 

 

 

NTCIP Object Reference - Ped Parameters (MM->5->4)

The maximum number of pedestrian detectors in the Naztec Ver 50 software is 8 (NTCIP 1202  - 2.3.6 MAXIMUM PEDESTRIAN DETECTORS).
 Det#, the pedestrian detector number (shown in red in the above table) is a "read-only" object and cannot be changed by the user (see, 2.3.7.1 PEDESTRIAN DETECTOR NUMBER).  

Call

2.3.7.2 PEDESTRIAN DETECTOR CALL PHASE PARAMETER - The Call Phase parameter determines the phase to which the pedestrian detector input is mapped. To disable the Pedestrian input, enter a value of 0.

NoAct

2.3.7.3 PEDESTRIAN DETECTOR NO ACTIVITY PARAMETER - The No Activity parameter is a diagnostic feature. The detector is considered to have failed if it does not exhibit an actuation for the specified amount of time (0-255 min). The Pedestrian Detector Alarm Status shows the detector's failure mode. To disable this feature, enter a value of 0. 

MaxPres

2.3.7.4 PEDESTRIAN DETECTOR MAXIMUM PRESENCE PARAMETER - The Maximum Presence parameter is a diagnostic feature. If the detector exhibits a constant actuation for the specified amount of time (0-255 min), then the detector is considered to have failed. The Pedestrian Detector Alarm Status shows the detector's failure mode. To disable this feature, enter a value of 0.

ErrCnt

2.3.7.5 PEDESTRIAN DETECTOR ERRATIC COUNTS PARAMETER - The Erratic Counts parameter is a diagnostic feature. The detector is considered to have failed if it exhibits too many actuations per minute. The Pedestrian Detector Alarm Status shows the detector's failure mode. Enter the data as the number of counts per minute (0-255 cpm). To disable this feature, enter a value of 0.
