The Nose Monitor was designed for simple installation. For the LonMark Noses, use two twisted pair cable (four conductor), unshielded, two connections for power and two for data transfer.

Digital Noses use LonTalk® protocol for all communication and data transmission, and the Neuron microprocessor developed by Echelon® Corporation. This allows Noses to be directly interfaced with any LonWorks® open system network in a customer's facility, including any building control system using the LonTalk protocol. Each Nose has a unique identity and position within the data collecting system, allowing multiple Noses to be connected on a single communication line, in any topology.

The Analog Nose uses a simple six-wire connection. Two terminals supply the 24 VAC power. One terminal is a common ground and the remaining 3 connect temperature, humidity and carbon dioxide.
