Dry or wet contacts required


Some Access Control Panels are designed with “Supervised” or “Dry contact” requirements for the inputs and have no common ground between the ACP (Access Control Panel) and device at the door. “S...
Schlage offers the “RLBD” to support these supervised or dry contact interface applications. The "RLBD" plugs directly into the PIM400-TD2 or PIB300-TD2 for easy hook-up.  
Please reference this Tehnical Note RLBD SES-20120418 for RLBD setup, use information, hook-up diagrams and some testing suggestions when connecting to a Supervised dry contact Access Contro...
