This Honeywell adaptor is required for use with the duct mount kit for MPD models of the Honeywell XNX universal transmitter. When combined with the MPD Interface Adapter (1226A0382), the duct mounting kit can accommodate the MPD to detect flammable gases in a duct application. The duct mount kit includes the adapter, gasket and required fasteners. The MPD Interface Adapter includes only the adapter and requires the S3KDMK duct mount kit.
