The local fire department, local building official, facility safety officer, or their designees shall be invited to witness the smoke tests, and the tests shall be witnessed by the reviewing authority. The areas to be tested shall be at least one each of a typical dormitory and one of each typical celled areas area, such as intake, medical, segregation and each configuration of general housing, as determined by the reviewing authority.

E. Smoke machines to perform the tests shall be furnished by the owner or the owner's contractor. Smoke machines provided shall be of sufficient size and capacity to perform the tests in a short period of time.

F. Understanding that there are many variables involved, the desired results of the tests are as follows: from start of smoke machine to system alarm shall be two minutes or less; from system alarm to system activation shall be 30 seconds or less; from system activation to distinguish an egress path from the center of the room to an exit shall be two minutes or less; and from system activation to the space being sufficiently clear to reset the system shall be 30 minutes or less.
