The ACS100 control panel allows for the attachment of one additional reader directly to the ACS100 control panel for the purposes of in/out scenarios (anti-passback). As such, the ACS100 is compatible with a large number of standard OSDP reader models including the following (UL tested for compatibility) reader models: OSDP reader 921PTPTEK00385. Brivo products are designed to accommodate the latest updates in OSDP using RS-485 reader formats. The ACS100 control board is compatible with OSDP readers using RS-485.
A current list of compatible readers and keypads is maintained on Brivo’s website at www.brivo.com. If you have a specific model of reader or keypad that is not listed on the Brivo website, please contact Technical Support at 1-866-BRIVO-4-U to determine compatibility.
