SECTION 14000

ELEVATORS

PART 1 - GENERAL

Description
Elevators shall be holeless hydraulic with submersible power units.  Passenger elevators shall have stainless steel doors, frames and interior returns with tamper proof fasteners.  Elevator doors shall have chip guard edges.  Provide emergency lights, ADA approved phone, and alarm.  Provide cab protection pads.  Cargo elevators shall have wall pads installed, bumper rail, and lock off system.  Passenger elevators shall have capacity of 2500 # minimum single jack type.  Cargo or freight elevators shall have capacity of 4000 # minimum dual jack type.  Special capacity requirements may exist for specific departments or buildings.  Elevators shall travel at 125 fpm for less than 3 floors, 150 fpm for 3 or more floors. All elevators shall be designed and inspected to meet ANSI 17.1, ASME A17.1, ADA requirements, NFPA, and CSM Standards and Commissioning.

Phone installation shall meet ADA and CSM requirements for emergency responses when there is a problem with the elevator operation.  Contact CSM Facilities Management for programming.

Consultants are advised that the State of Colorado has adopted the requirements of ASME A17.1. This code impacts the following areas: sprinklers and smoke detectors located in the hoistway and machine room, shunt trip of elevator power and sump pumps. The campus, in consultation with the State elevator inspector have developed a standard for elevator configuration that complies with this code as follows: The hydraulic oil and elevator cab shall be constructed of noncombustible materials and certified as such by the manufacturer. The hoistway enclosure shall be constructed of fire resistive construction. Fire sprinkler heads and smoke/heat detectors are not to be installed at the top of the hoistway. A heat detector with shunt trip control of the elevator shall be installed in the elevator machine room within 2 feet of the fire sprinkler head. A smoke detector shall be installed in the machine room to recall the elevator. A sump pump with an oil sensor shall pump pit water to the sewer via an air gap. The sump pump controller panel shall not be installed in the hoistway or machine room.

PLEASE COORDINATE WORK OF MECHANICAL AND ELECTRICAL CONSULTANTS WITH THESE REQUIREMENTS.

Provide a one year parts and labor warranty from date of final building acceptance.  Provide one year of full preventative maintenance service and 24 hour emergency service.

Elevator Controls
Elevators shall be furnished with Motion Control Engineering (no substitution will be accepted).
Door operators shall be high speed heavy duty with a minimum speed of 2 ― fps.
Door protection shall be infrared, full screen device with differential timing, nudging, and interrupted beam time.
Firefighters service phase I and II including alternate floor return.
All signal fixtures shall be tamper/vandal resistant with led illumination.
Emergency battery back-up elevator-lowering device that automatically activate if there is a loss of power. (Coordinate with Electrical Engineer)
Fire Protection
Provide elevator equipment room and hoistway with sprinkler system when required:
 

Rate-of-rise heat detectors in elevator machine rooms shall be arranged to automatically disconnect the main power feeding the elevator equipment.
 

Rate-of-Rise heat detectors installed in the elevator pit shall be arranged to initiate Phase One re-call. 
 

In each case, the detector must be placed within two feet of the sprinkler head. The sprinkler rating shall exceed the heat detector rating. 
 

The heat detector in the machine room shall cause a shunt to trip a circuit breaker, disconnecting the main power to the elevator equipment prior to initiating pre-action sprinkler system. 
 

Power shall be manually restored. 
 

The smoke detector circuit shall be separated from the thermal detector circuit.
 

Elevator having 25 feet and over vertical travel
 

Smoke detectors shall be placed in each elevator’s lobbies, elevator’s equipment room and hoistway.
The activation of any smoke detector within elevator lobbies, elevator equipment room and hoistway shall put the elevator into fire recalls.
Elevator shall have two alternative floor recalls (primary and secondary).
The elevator shall return to the secondary recall only if the smoke detector on the primary recall is activated.   
Elevator hoistway venting
Hoistway venting per IBC latest state adopted edition.
Elevator shall be constructed with non-combustible materials with minimum of 1-hour rating.
Venting in the hoistway shall be provided to relieve pressure and smoke within the hoistway or shaft.  The area of the vent shall not be less than 3.5% of the elevator shaft or a minimum of three ft2 per elevator.
