How to Read a Listing

BTL listings are written in a standard format for all manufacturers and profiles. The graphic below explains how to interpret each field.

 

 

BTL Listed Product vs. Product in the Member Product Catalog

The BTL maintains a list of BACnet products that have been independently tested and it is located here. In addition to the BTL Listing, BACnet International maintains a catalog of BACnet products. Most of the products in the catalog are also in the BTL Listing. However, some products in the catalog are not in the BTL Listing. There are a variety of reasons why a product might not be in the BTL Listing, including:

  • it may have been BTL Listed at one time but has since been archived due to obsolescence or for other commercial reasons;
  • it may be currently undergoing testing and will be BTL Listed in the future;
  • there may be no BACnet specific test (for example, RS-485 twisted pair wire);
  • it may not have been independently tested at a Recognized BACnet Test Organization.

Member Product Catalog search results include links to PICS documentation and indicate the BTL Listing status of each product. 

 

BTL Listings by Manufacturer Help

All products in the BTL Listings have been tested according to the BTL requirements.  Searching by Manufacturer will result in a page that includes all of their listed products.


BTL Listings by Device Profile Help

All products in the BTL Listings have been tested according to the BTL requirements.  Searching by Device Profile will result in a page that includes all listed products that conform to the selected profile.


Frequently Used Terminology

BACnet International - is a not-for-profit organization that encourages the successful use of BACnet in building automation and control systems through product testing and certification, educational programs, and promotional activities. BACnet International members include companies and individuals involved in the design, manufacturing, installation, commissioning, maintenance and operation of control equipment that use BACnet for communication, as well as other interested persons.  BACnet International complements the work of other BACnet-related groups, including the BACnet standards development committee (ASHRAE SSPC 135).

 

BTL - The BACnet Testing Laboratories (BTL), administered by BACnet International, defines conformance test requirements based on ASHRAE Standard 135.1 for BACnet products.  The BTL also coordinates the global process of conformance testing, certification and listing of BACnet products.  Products that are independently tested according to the BTL requirements are eligible to display the BTL Mark.

 

BTL Mark – A graphic displayed on products that have completed the BTL approved conformance testing process and are listed on the BTL website.  

 

BTL Working Group – The BTL Working Group (BTL-WG) is a global group of BACnet experts that formulates evolutionary changes to testing standard 135.1, and which defines the Test Plan governing the tests needed for BTL Certification and the corresponding BTL Listing and the right to display the BTL Mark.

 

Device Profile – Device profiles are BACnet device categories defined in the BACnet standard.  Devices that implement all the required BACnet capabilities can claim conformance to that profile.  Devices may claim conformance to multiple profiles according to specific rules specified in the BACnet standard.

 

PICS – The Protocol Implementation Conformance Statement contains information defining all of the BACnet capabilities of a device.  PICS are available for all products in the BTL Listing and can be downloaded directly from the product listing page. 

 

About BTL Listed Products

All products in the BTL Listing were independently tested according to the BTL requirements.  Note that this is not true for all products in the BACnet International Member Product Catalog.

 

All products in the BTL Listing are eligible to display the BTL Mark according to the guidelines established by the BTL. Marketing use of the BTL Mark in conjunction with such products is restricted according the guidelines established by the BTL.

 

In order to be included in the listings a product must be tested by a Recognized BACnet Testing Organization.  These organizations have passed a rigorous examination to ensure they have the capability to conduct testing in accordance with the BTL requirements.

 

Products that implement all of the required capabilities for a particular profile are listed under that profile or a profile of lower capability depending on its intended application. Many products include additional capabilities beyond those required for their profile. The actual capabilities of each product are outlined in its PICS.

 

When looking for particular system functionality (such as a VAV controller), it is useful to search under several device profiles since vendors may provide that functionality in devices with different BACnet capabilities. For example, a VAV controller could reasonably be listed with a B-ASC or B-AAC profile.  In the same way, a communicating thermostat device could reasonably be listed with a B-ASC or a B-SS profile.

Notes on the use of this Site:

 

1) This site is intended to provide users and suppliers with useful information to enhance their assessment and utilization of BACnet products and systems. It is the global reference site for BTL Certified and Listed products.

2) Substantial efforts are made to ensure product information is accurate and current.  However, suppliers are the best source for the most current information on their specific products.

3) BTL testing requirements as referenced on this site are extensive but cannot be exhaustive. For more details on specific product testing review the BTL Listing document for that product (available by clicking on the BTL Listing date in the product listing).  For BTL testing policies and procedures review the current BTL Test Package.
