In order to make sure we provide everyone with the most up-to-date CSFM listing documents, we would like to direct you to the ca.gov website.

CA.GOV CSFM Listing Documents

Search Suggestions: On their site, there are three drop-downs: Category, Company, and Listing. We would suggest that you ignore the first drop-down, "Category". In the second drop-down, "Company," select 1653 -- System Sensor. Ignore the third drop-down and just click the "search" button. 

After the results are displayed, do a "control F" to initiate a "find" and then type in the System Sensor model number you're interested in finding. This should make it a little easier to find the documents of interest.

The FM Approval Guide contains information about tens of thousands of products and services tested and FM Approved, as well as engineering data and technical information on the application and use of listed products. Registration is free and is required.

Explanation of Published Voltage, Current, and SPL Specifications

In May 2004 Underwriters Laboratories changed standards UL 1971 & 464 to require that operating current measurements are made using RMS (root mean square) instead of peak or average values. RMS measurements more accurately predict the power consumption of a device since they take into account the entire current draw profile including surge, repetitive surge, and peak values. The published RMS current is the maximum operating current of that device within its operating voltage range. This current maximum may or may not occur at the endpoints of the voltage range.

Similarly, UL tests the audibility of devices by measuring them across the operating voltage range to determine the minimum sound pressure level produced at any particular setting.

During May 2004, UL also changed the way they list the voltage range of a device. All 12V products will be listed between 8 - 17.5V and all 24V products will be listed between 16 - 33V. Those devices are considered “regulated.” Any product that does not operate within these ranges will be listed as a “special application” with its operating voltage specified on the device.
