Smoke detectors are specified in Section 13852, "Interior Fire Detection and Alarm
System," or Section 13855, "Analog/Addressable Interior Fire Alarm System," including
conduit and wiring from each smoke detector to elevator controller. In elevator section,
provide connections to elevator controls, which will, when smoke is detected by any
smoke detector, activate visual and audible signals and send each elevator to the
designated floor as required by ASME A17.1 (Rule 211.3b, Smoke Detectors). Indicate
detectors and connections on fire protection drawings or on electrical drawings if fire
protection drawings are not provided. Coordinate with Electrical Engineer.
7-2.2 For electric traction elevator with 2-hour fire rated hoistway, sprinkler(s) are not required
by code for the hoistway. Sprinklers are required in the electric traction elevator machine
room (except in Italy). Actuation of the flow switch shall remove power to the elevator
by shunt trip breaker operation. The flow switch shall have no time delay.
7-2.3 In buildings protected with an automatic sprinkler system, provide protection of hydraulic
elevator installations as follows (except in Italy):
a. Machine Room: Provide a sprinkler(s) with sprinkler guards in the machine room.
Provide a supervised shut-off valve, check valve, flow switch, and test valve in the
sprinkler line supplying the machine room. These items shall be located outside of and
adjacent to the machine room. Actuation of the flow switch shall remove power to the
elevator by shunt trip breaker operation. The flow switch shall have no time delay.
Coordinate with Electrical Engineer.
b. Elevator Pit: Provide a sidewall sprinkler(s) with sprinkler guards in the pit for
hydraulic elevators. Locate the sprinkler no more than 2'-0" (609 mm) above the pit
floor. Provide a supervised shut-off valve in the sprinkler line supplying the pit.
Locate the valve outside of and adjacent to the pit. Actuation of the pit sprinkler shall
not disconnect power to the elevator.
c. Elevator Hoistway: Provide a sprinkler(s) at the top of the hoistway for hydraulic
elevators with cylinder or supply piping extending above the second finished floor
elevation. Provide a supervised shut-off valve, check valve, flow switch, and test
valve in the sprinkler line supplying the hoistway. These items shall be located outside
of and adjacent to the hoistway. Actuation of the flow switch shall disconnect power
to the elevator by shunt trip breaker operation. Flow switch shall have no time delay.
Coordinate with Electrical Engineer.
d. Test Valve: Provide inspector's test connection for each flow switch associated with
the elevator machine room and/or elevator hoistway sprinklers. Locate the test
connection outside the rated enclosure. Route test connection piping to a floor drain
location that can accept full flow or where water may be discharged without property
damage. Discharge to a floor drain shall be permitted only if the drain is sized to
accommodate full flow. Discharge to janitor sinks or similar plumbing fixtures is not
permitted.
