Building codes require a minimum of one smoke groups during closure for stairs serving floor levels more than____ feet below the level of exit discharge. 30'. Page 116
Typically, smoke proof steering closures are on the exterior perimeter of the building and are entered through ventilated vestibules or open exterior balconies. Page 116 A passive smoke proof stairwell enclosure is accessed by using a vestibule or an exterior balcony. Page 117
Three methods of passive smoke containment: Vestibule open to atmosphere. Open air balcony. Smoke shaft open to atmosphere. Page 118 Hydraulic elevators do not have brakes, cars are slowed and stopped by controlling the flow of hydraulic fluid back into the reservoir. Page 120
Building codes typical allow the use of open stairs and buildings only when they connect no more than two adjacent floors above the basement level. These stairs are sometimes referred to as______. Convenience stairs. page 118
This type of elevator is a passenger elevator that has been designed to carry freight. Service elevator. Page 119
Electric elevators are subdivided into either ___ or ___ devices. Drum or traction devices. Page 120
This type of elevator is obsolete and is found only in very old structures. However they still may be found in use as freight elevators. Drum elevators. Page 120
During normal operation, the brakes on traction elevators with AC motors a directly and stopping the car at the correct floor. Page 121 On elevator cars with DC motors the brakes do not play any part in actually stopping the elevator car. The motor stops the car and then the brakes are applied to hold the car in place. Page 121
_____ is an electric switch design to stop the elevator car by removing power before it reaches the upper or lower limits of the hoistway. A terminal device. Page 121
This elevator safety feature are large springs or hydraulic cylinders and pistons located at the bottom of the pit that act as shock absorbers should the terminal switch fail. Buffers. Page 121
This elevator safety feature is also known as the speed governor. Slows the drive motor when an elevator starts to exceed a safe speed. Speed reducing switch. Page 121
This elevator safety feature is activated if the speed reducing switch fails to slow the car sufficiently. Overspeed switch. Page 121
This elevator safety feature are tapered sets of steel jaws that wedge against the guide rails and bring the elevator to a stop. Car safeties. Page 121
Elevator hoistway enclosures usually are required to be a fire rated assembly with a__ or __ hr rating. One or two hour rating. Page 122
If an elevator hoistway is not vented at the top, the acumulated hot gases and smoke me tend to what? Mushroom. Page 122
If a building contains 3 or fewer elevators, the codes permit them to be placed in one hoistway. Page 123 When four or more elevators are provided, there must be a minimum of two separate hoist ways. Page 123

Sometimes interstitial spaces the space between a suspended ceiling and the roof deck are used as a return air plenum. Page 134 Smoke control means the use of mechanical equipment to produce pressure differences across smoke barriers to inhibit smoke movement. Page 135
The automatic transfer HVAC to fire operations can be done by ____, ____, or ____. Smoke detectors, sprinkler water flow switches, or heat detectors. Page 135
Continuing the supply of air to the non fire floors creates a ______ of higher air pressure on floors above and below the fire floors. This reduces the migration of smoke into those areas. Pressure sandwich. Page 135
When an HVAC system has both automatic and manual capability come of the manual shall take priority over the automatic control. Page 137 A smoke control system should not be activated with the manual pull station. This is to avoid the possibility of occupants seeing a fire but not operating pull station until they have fled to another area of the building. Page 137
