hoistway. The circuit for elevator controller actuation of Firefighters'
Service shall include only these smoke detectors. In lieu of dual-contact
smoke detectors, an addressable fire alarm system with listed smoke
detectors can be used in the above stated locations. Ensure that all smoke
detectors are mounted on finished ceiling. Smoke detector system must
comply with ASME A17.1.
2.2.3
Fire Sprinklers
**************************************************************************
NOTE: Virtually all new elevator installations
require fire sprinklers in each elevator machinery
room. Electric traction elevators are required to
have a 2 hour rated hoistway, which does not require
sprinklers. If a 2 hour rated hoistway cannot be
achieved, sprinklers are required and include the
bracketed options for hoistway sprinklers in the
following paragraphs.
**************************************************************************
Provide fire sprinklers in accordance with Section 13930N WET-PIPE FIRE
SUPPRESSION SPRINKLERS; providing dual contact flow switch, check valve,
and shutoff valve in each sprinkler line immediately outside of each
machine room[ and hoistway] in accordance with ASME A17.1.
Provide electrical connection to fire sprinkler system in accordance with
Section 16402 INTERIOR DISTRIBUTION SYSTEM. For each elevator, provide
control wiring connecting the flow switch to the shunt trip equipped
circuit breaker within the electrical panel serving the main line
disconnect. Upon flow of water, flow switch shall instantaneously send a
signal to cause opening of shunt-trip equipped mainline circuit breaker, in
compliance with ASME A17.1, Rule 102.2(c)(4), and send a signal to fire
alarm control panel to indicate water flow condition. Machine room
sprinkler flow switch actuation shall shunt trip all elevators served by
the machine room.[ Hoistway sprinkler flow switch actuation shall shunt
trip all elevators in the hoistway.]
2.2.4
Top-of-Car Operating Device
ASME A17.1, Section 306, Rule 306.2. Provide elevator with an operating
device, mounted on or from the car crosshead, that will permit car
operation at a speed not exceeding 0.75 mps 150 fpm for purposes of
adjustment, maintenance, testing, and repair. Include an integral or
remote safety device, "UP" and "DOWN" switches or buttons, an emergency
stop switch, and inspection switch.
2.2.5
Hoistway Access Switches
ASME A17.1, Section 110, rule 111.9. Provide key-operated hoistway access
switches that permit limited movement of the car at terminal floors for car
door opening and car positioning, operative only when the "INSPECTION"
switch in car operating panel is in inspection position. Locate switch
1800 mm 6 feet above floor level, with in 300 mm 12 inches of hoistway
entrance frame of an elevator or with the ferrule exposed when located in
entrance frame.
