Question

Answer Published 06/03/2016 at 2:37 PM

No. It is not the intent of the Code to override licensing
or local governance. The determination of specific task
assignment is based at the local level based on licensing,
qualifications, competence and decisions of the governing
officials. Please see the attached commentary for additional
information

Commentary

As a couple examples, some of the jurisdiction in Florida perform the testing as follows: One jurisdiction - The code does address the testing of the CO sensors. Since it activates a mechanical system in this jurisdiction, the mechanical inspectors witness the test, just like for a duct smoke detector. Another - Mechanical inspectors check co sensors in the City. They check the location and test with gas marked 25ppm, provided by the contractor. Yet another method - This municipality depends on the Fire Department to test the functionality of all commercial fire systems. An electrical inspection is done to verify the integrity of the installation, but performance testing is up to the Fire Department. As can be seen, a variety of methods are used. It is best to check with the AHJ to ensure the method which method is used and the correct inspectors are present, as required by them.
