Appendix A1: Devices Needed for Initial Site Installation.
Fit and wire the following external devices to the controller terminals to allow the system to
operate under “Inspection Control” for initial site installation. Additionally set “Hoist Mode” in the
MMI checklist so door limits and car network events are ignored.
If in doubt please contact the factory.
[#] These devices are optional features and may not be fitted on all control panels.
Refer to the site-specific drawings for further details.
