- ." (b) In buildings where more than one standpipe is provided, they need not be interconnected. (c) Piping may be hydraulically sized. C. The purpose of smoke control is to restrict movement of smoke to the general area of fire origin and to maintain means of egress in a usable condition. 1. The smoke-control system shall be activated by operation of either the sprinkler system, smoke detectors, or may be manually operated, subject to approval of the building official. Smoke detectors shall be provided within the return-air portion of the air condition system as required by the Uniform Mechanical Code. Smoke detectors which will sound a local alarm also shall be provided on the tenant side at openings where open-type security grilles are used. Actuation of either the duct detector or the sprinkler system shall cause the air supply to the air conditioning zone in which the fire occurs to shut down. During those hours when the air conditioning system is not operating, smoke detector or sprinkler actuation will transmit an alarm only as required in 15.44.040 (A)(l) herein. 2. The mall shall have smoke-removal capability installed in or near the roof. Such facility may be either natural or mechanical. 3. Before the smoke-control system is accepted by the building official, it shall be tested in his presence to confirm that the system is operating in compliance with the requirements of this subsection.

Rooms or areas containing controls for air conditioning systems, automatic fire extinguishing systems or other detection, suppression or control elements shall be identified for the use by the fire department. E. Each tenant space shall be separate from other tenant spaces by a wall having a fire-resistive ratio of not less than one hour. The separation wall shall extend from the floor to the under- side of the floor or roof above. Except as required by other provisions of this code, the ceiling need not be a fire-resistive assembly. A Separation is not required between any tenant space and a mall, except for occupancy separations required by Section 15.44.060. F. When a public address system is provided, the system shall be made accessible to the fire department. G.

They shall not exceed 20 percent of the wall area facing the mall; 2.
