When inspecting the equipment, it’s advisable to use the post-installation checklist. There are a number of features to be inspected at each device and it’s easy to miss one without a checklist to remind the inspector of each feature to check. Some easily missed failures can include:
- Vibrating arrow/button: stopped working
- WALK indication: stopped or delayed
- Raised arrow: missing or misaligned
- Pushbutton: jammed or malfunctioning (although this is less common with the newer pushbuttons)
- Ambient noise response: slow or not responding
The problems listed here are some of the more common failures that may be observed at malfunctioning APS. The inspector should pay special attention to these features, since some of these problem may not be obvious on a cursory glance.
