Why is my Schlage Control Unit PIM400-485 not communicating with the Access Control Panel?

  Several factors could be preventing communication. The RS485 cable might be damaged and need replacement. The RS485 signals could be incorrectly wired, so check the wiring instructions. The RS485 address of the PIM400-485 might not match the address in the Access Control Panel, requiring you to adjust the PIM400-485 address. Also, verify that the 2|4 wire jumpers (P5) are correctly installed or removed depending on whether you're using RS485 2-Wire or 4-Wire communication.

What to do if my Schlage Control Unit PIM400-485 reports false tamper detections to the Access Control Panel?

  False tamper detections can occur due to a few reasons. If you have a version 2 model, an intense light source might be interfering with the optical receiver; move the PIM400-485 away from the light and ensure the enclosure cover is installed. Also, improper wiring can cause interference, leading to false tamper detection. Make sure the wiring is properly routed.

How to fix Schlage Control Unit PIM400-485 when it does not communicate with Wireless Access Point Modules (WAPMs)?
- A
  Amy HarringtonAug 23, 2025
  If the PIM400-485 isn't communicating with WAPMs, first ensure that the Antenna Module is properly installed and seated. Wiring might be causing interference with the internal antenna, so check the wire routing in the PIM400-485 enclosure and clear the area around the internal antenna of any wire. Finally, the PIM400-485 may not be linked to the Wireless Access Point Module (WAPM) - link the PIM400-485 to the Wireless Access Point Module.
