| General Requirements Requirements for installation vary by type of equipment selected.
These general requirements will serve as a guide to assist you in preparing your
building for the installation of Schindler elevators.
All designs, clearances, construction, workmanship and

the ASME A17.1 or CAN/CSA-B44 Code plus applicable Building Code. For specific rules,
refer to ASME A17.1 Part III or CAN/CSA-B44 Section 4 for hydraulic elevators. Local
requirements must be used if more stringent.
Items To Be Provided
To complete the installation, the following items
must be considered, which are not included in the elevator contract:

not to exceed ½" (13mm) at any point. Two-hour fire resistance rating of hoistway
walls or rating to meet applicable local codes.

recesses or setbacks over 2? (51mm) ASME A17.1 or 100mm CAN/CSA-B44 except on side used
for loading or unloading.
3. Number of cars in hoistway, minimum
size of cars, venting and fire rating of doors and entrances must be specified per
applicable Building Code.
4. Supports for rail brackets at pit,
each floor and roof. Maximum allowable vertical spacing of rail supports, without backing
Divider beams between hoistway at each floor and roof, for guide rail bracket supports.
5. Supports for jack guide rail brackets
and jack synchronization chains to the hoistway walls and pit.
6. Light outlet for each elevator, in
center of hoistway, pit and machine room, as indicated by our elevator contractor.
7. Recesses, supports, and patching, as
required, to accommodate hall button boxes, signal fixtures, etc.
8. All barricades either outside elevator
hoistway or between elevators inside hoistways as required.
9. Dry pit reinforced to sustain normal
vertical forces from rails, jack units and buffers. Pit to be level and free of debris at
jack unit locations. Consult Schindler sales representative for rail forces, chain
attachment forces, jack loads and buffer impacts. Where space below pit floor can be
occupied, consult Schindler sales representative for special requirements.
10. Convenience outlet and light fixture
in pit with switch located adjacent to access door per ASME A17.1 Rule 106.1e and
CAN/CSA-B44 2.7.5.
11. Where access to pit is by means of
lowest hoistway entrance, vertical ladder of non-minimum above sill of access door or
handgrips shall be provided to the same height.
12. Coordinate sump hole location in pit
with Schindler representative to avoid interference with jack unit locations.
Machine Room
13. Enclosed and protected machine room.
14. Access to machine room and machinery
space as required by governing code or authority.
15. Lighting, convenience outlets,
heating, cooling and ventilation of machine room and machinery space. Machine room
temperature to be maintained between 55° F and 90° F (13° C and 32° C) . Relative
humidity to be maintained at 95% or less non-condensing.
16. A fused disconnect switch for each
elevator and light switch located per National Electrical Code, (NFPA No. 70), and where
practicable, located inside machine room adjacent to door.
17. Suitable copper feeder, ground and
branch wiring circuits for signal system and power operated door, including main line
switch. Feeder and branch wiring circuits for car light and fan, including main line
switch, Ground fault protection as required by NEC 620-85.
18. Clear access above ceiling, or
metal/concrete raceways in floor, for oil line and wiring duct from machine room, if
machine room is remote from elevator hoistway.
19. Cutout through machine room wall,
8" x16" (203mm x 406mm), for oil line and wiring duct. Coordinate with Schindler
construction superintendent at building site.
20. Hoisting beams, trap doors, ladders
or stairs and other means of access to machine room for maintenance and equipment removal
purposes.
21. Convenience outlet and telephone
outlet on control panel,.
22. All conduit and wire runs remote from
either the machine room or the hoistways.
23. Heat, smoke or products of combustion
sensing devices connected to elevator machine room terminals when such devices are
required. Make contacts on the sensors should be sized of 120 volt D.C.
Emergency Provisions
24. Elevator Firefighter's and other
emergency services are required in certain buildings, depending on height of the building
or number of landings.
25. Elevator Firefighter's Service is
required per ASME A17.1 Rule 211.d and may be required per CAN/CSA-B44 3.12.15.1.1.
Elevator Firefighter's Service wiring and interconnections to automatic sprinkler systems
or heat and smoke sensing devices furnished by other. Emergency services may be required
by Building Code.
26. When emergency/standby power
operation of elevators is required, the Electrical Contractor should coordinate with out
elevator contractor for operation requirements.
27. Provisions for earthquake protection,
dictated by the Building Codes, may be required. Consult your elevator contractor for
special requirements.
Entrances
28. Hoistway walls are to have a fire
resistance rating in accordance with ASME A17.1 Rule 100.1a.
29. Furnishing, installing and
maintaining the required fire rating of elevator hoistway walls, including the penetration
of fire wall by elevator fixture boxed, is not the responsibility of the elevator
contractor.
30. The interface of the elevator wall
with the hoistway entrance assembly shall be in strict compliance with the elevator
contractor's requirements.
31. Entrance wall and finished floor are
not to be constructed until after door frames and sills are in place.
a. Where front walls
are of reinforced concrete, the concrete openings must be minimum 12" (305mm) wide
[6" (152mm) on each side] and 6" (152mm) higher than the clear opening
(including transom height).
b. Where drywall or
sheet rock construction is used for front walls, it shall be of sufficient strength to
maintain the doors in true lateral alignment. Drywall contractor to coordinate with the
elevator contractor. Note : A support member (spreader beam) must be provided for floor
heights greater than 12'-0" (3658mm) to support entrance header struts.
c. Door frames are to be
anchored to walls and properly grouted in place to maintain legal fire rating (masonry
construction).
32. For applications requiring grouted
sills, provides sill supports with 2½" x 4" (64mm x 102mm) minimum floor recess
the full width of the hoistway. Grout full length and width after sills are set.
33. Filling and grouting around entrance.
34. The use of 18 gauge. (.048")
materials for doors have UL approval.
35. When fixtures are mounted in drywall
side jambs, wall thickness may increase. Requirements must be coordinated with your
elevator contractor.
36. Where openings occur, all walls and
sill supports must be plumb.
37. When sill supports are provided by
the elevator manufacturer, hoistway should be capable of accepting anchor stud type
fasteners.
38. When fluted steel decking is used
under concrete flooring, the concrete must be no less then 4' (102mm) thin; 2½"
(64mm) thick for sill angle anchors. |
