2 Introduction Niagara Belco Ltd has been in the elevating industry for 30 years, we take pride in our work and aim to please all of our customers. We appreciate your business and always looking to improve. If there are items in this guide that you believe should be improved please give us your feedback. Thank-you. Limited-Use / Limited-Application or LU/LA Elevators are designed to service schools, libraries, low rise, low occupancy commercial buildings, churches and multi-family housing. It provides the functionality of a commercial elevator with the practicality and economies suitable for these applications. It can be designed to fit into any décor and be as elaborate or simplistic as desired. This design guide will assist architects, general contractors and elevator professionals in the planning for a LU/LA installation in accordance with ASME A17.1 and CAN/CSA B44. Please note all dimensions and specifications contained herein are nominal and should only be used in the early planning stages. Construction of the actual hoistway and related LU/LA requirements should be based off job-specific application drawings.

The elevator contractor is not responsible for the structural design of the building and its ability to support the elevator loads and/or reactions. 3. Where wood frame construction is used, refer to rail load drawing and consult building project architect/engineer to design rail support wall. 4. For masonry walls, inserts shall be provided by the elevator contractor and installed by the general contractor. 5. Total travel distance from finished bottom floor to finished top floor must be held within 1 of that shown on the layout drawings. 6. Overhead clearance: (Top floor to underside of hoistway ceiling or obstruction) to be maintained per the layout drawings. If any of the hoistway dimensions cannot be achieved, contact the factory for alternate arrangements. 7. A poured pit conforming to the dimensions indicated on the layout drawings must be provided. The pit must be designed for the impact load indicated and must be dry and level from wall to wall. 8. A sump pump is NOT necessary unless required by local code. Where water seepage is encountered a sump pump and sump pump hole with cover is recommended in the elevator pit. G.F.C.I. receptacle is required. If a sump pump is furnished, coordinate location with the elevator contractor. 9. A sprinkler is not required by elevator code. A sprinkler is not desired by Niagara Belco Ltd. If a sprinkler is installed in the hoistway a drain or sump must be supplied. Environmental issues may apply due to oil separation requirements which are the responsibility of the building General Contractor. Consult local building department. 10. A pit light with protective cage, light switch and duplex GFI receptacle are to be installed in the pit and wired by General Contractor s electrician as per layout drawings. 11.

5 1.3 Fire Recall Requirements TO BE PROVIDED BY SITE GENERAL CONTRACTOR/ELECTRICAL CONTRACTOR IMPORTANT Below are general guidelines as identified by TSSA. Every site is unique depending on elevator hoistway and elevator machine room configuration. The project s architect is responsible for determining the correct fire detector and alarm equipment necessary for the application. Niagara Belco is not responsible for determining what, if any, site specific equipment will be deemed necessary, or for providing the fire detector and alarm equipment. All new LULA installations require Phase 1 recall (ASME A /CSA ) ta be activated by fire alarm devices which are part of a fire alarm system. If possible all these devices and relays shall be part of the building fire alarm system if one exists. 0. Reg 350/ (2) If the existing fire alarm system does not contain the required detectors or is not able to provide the required relay outputs, Or There is no fire alarm system required or existing. Then a Protected Premises fire alarm system (CAD 250/11 A.1 (i) which only meets our requirements shall be provided. Code Adoption Document r (c) Input Devices Smoke detectors (or heat detectors if area not suitable for smoke detectors) shall be located; (Code Adoption Document r ) -At each elevator lobby (Code Adoption Document r (1)) -In the elevator machine room (Code Adoption Document r (2)) Smoke detectors(or heat detectors if area not suitable for smoke detectors) are not required to be installed in the elevator shaft by the elevator code (Code Adoption Document r (3)), but if they are installed as part of a building fire alarm system, then an alarm from these devices shall activate the appropriate relays below. (Code Adoption Document r (2)), 0 reg 350/ (2)(e) 4

6 Output Relays Main Recall Relay (ASME A /CSA ) - Minimum of one set of normally closed contacts rated for minimum of 1Amp at 120vac. - Shall activate upon any of the required input devices that do not activate Alternate floor relay. (ASME A /CSA ) Alternate Recall Relay (ASME A /CSA ) - NOTE: not required if the main recall floor is fully sprinklered. Code Adoption Document r (8), 0. Reg 350/ (b) - Minimum of one set of normally closed contacts rated for minimum of 1Amp at 120vac. - Shall activate upon any required fire alarm devices which are on the recall floor ( this includes the machine room device if it is on the recall floor) (ASME A /CSA ) - The pit device (if required) if it is at or below the main recall floor and the main recall floor is below the Alternate recall floor. (ASME A /CSA (d)), Code Adoption Document r (8) ie. The pit device will always cause a recall to the highest recall landing Flashing Fire Hat Relay (ASME A /CSA ) - Minimum of one set of normally open contacts rated for minimum of 1Amp at 120vac 5
