served and from the normal DOOR CLOSE button. This operation shall over ride other controls and all landing call buttons but shall be operational only when the Firemen service switch at the main landing is in the ON position.

- Once the Fireman registers the call for the desired floor, continuous pressure on the DOOR CLOSE button shall close the doors and start the elevator. Once desired floor is reached elevator is stopped until another similar operation is made by the fireman.

All elevators when on INDEPENDENT or inspection operation shall be signaled to return to the main landing when landing key switch is in the ON position or elevator is called by automatic detection means. - The emergency signal shall sound a distinctive tone, bell or gong located on

top of the car enclosure. All elevators if connected with automatic fire monitoring panel shall operate as follows when getting a signal from the main fire alarm and detection system through the relay contacts provided at the control panel located at each elevator machine rooms. - All elevators shall return nonstop to their main landing without responding to

registered car or landing calls. An elevator traveling away from the main landing shall stop and reverse its direction at its next possible landing without opening its doors.

- All car and landing buttons shall be rendered inoperative and all call acknowledging lights and waiting passenger lanterns shall be extinguished until the Firemen service mode is changed by the fire monitoring panel through the relay contacts.

- Once the elevator is reached at the main landing, it shall wait as standby elevator with its door in the open position until the Firemen service mode is changed by the fire monitoring panel through the relay contacts. The elevator shall return to the normal operation as soon as the Fireman's mode is cleared by the fire monitoring panel through the relay contacts.

2.21.2 Independent Service Operation: Independent operation, if required by the

schedule of specifications, shall be provided as follows: An Independent Normal switch shall be provided on the main car operating panel for all elevators specified for independent operation. When this switch is in the ON position, the elevator shall be operated from the car buttons only independent of all other operation modes. The doors shall remain open when an elevator is at a landing until the car button for another landing and the DOOR CLOSE button are pressed. If several car calls are registered, it shall be necessary, after each stop, to press the door close button to effect the closing of the doors.

PART 3 EXECUTION

3.1 SITE CONDITION INSPECTION Elevator Contractor shall verify elevator well plumb before preparing shop drawings, and report to the Engineer any proposed modification to equipment design to suit actual site conditions. During construction of building structure (prior to installing elevator equipment), examine elevator well and machinery spaces to verify that no

irregularity exists that could affect the quality of execution of the work as specified. Note: - Elevator well dimensions and plumb. Divider beam locations. - Support areas for beams, brackets, etc. - Pit dimensions and drainage. - Access means to pit, hoist way and machinery spaces. - Suitability of power sources, illumination and ventilation. Examine the work of other divisions, upon which the work of this section depends, and report defects in writing to the Engineer.

3.2 PAINTING Apply a coat of rust inhibiting paint, either in the field or at factory, to exposed ferrous metal surfaces of controller cabinet, machine, struts, header, dust cover, rail brackets, working platform, car frame, buffers, buffer extensions, ladder, working platform, and any other ferrous metal product supplied. After installation and final cleaning, re-paint the non-machined surfaces as required. Ferrous metal surfaces that will be concealed in the completed work shall receive a factory applied primer and finish coat of rust inhibiting paint. After installation, but before work is done to conceal the item, clean and repaint damaged areas.

3.3 CLEANING Prior to start of Acceptance Testing, ensure that all installation work is complete, including: Clean machine room, pit, top of car, and elevator well blow out controllers. Make all wiring runs neat, and connect all spare wire to terminals. Remove all non-permanent equipment from machinery spaces.

3.4 TESTING AND TRAINING Third party testing certificate of the installation shall be provided. Training of the Employer staff on the maintenance and operation of the elevators and controls shall be provided.
