Note: The discontinuation and end-of-support of the Secure NAE Engine (NAE-S) is effective from July 2021.

The NAE-S model:

  • supports up to two RS485 field buses into a Metasys system network. The NAE551S model integrates two N2 Buses, two BACnet MS/TP trunks, or one N2 Bus and one BACnet MS/TP trunk. Each bus or trunk may contain up to 100 field controllers. A LonWorks network NAE-S model is not offered. The NAE-S can also monitor and supervise a number of BACnet IP devices; the total number of BACnet IP devices depends on the number of objects each device supports.

  • supervise BACnet/IP field controllers from Johnson Controls, such as the FAC4911 Advanced Application Field Equipment Controller and the VMA1930 Variable Air Volume Modular Assembly.

  • communicates on an encrypted network with other encrypted NAE-S engines or unencrypted network engines. The NAE-S is a hardened version of the NAE55-series network engine. This network engine has embedded encryption technology under a securely fastened enclosure to protect and secure the building automation system at the endpoint.

  • serves as a Site Director supervising a maximum of four other NAE-S engines over the encrypted network.
