2.29.1 Identification of Equipment
JUMP TO FULL CODE CHAPTER
In buildings with more than one elevator, each elevator in the building shall be assigned a unique alphabetic, numeric, or alphanumeric identification. Where destination-oriented control for operation is provided, the same unique identifier for each elevator shall be used for both the destination-oriented designation and the designation required by 2.29.1.1.
The identification assigned in 2.29.1.1 shall be a minimum 50 mm (2 in.) in height unless otherwise specified, and a contrasting color to its background. The identification shall be painted on, engraved on, securely attached to, or adjacent to the following equipment associated with each elevator or the enclosures housing the following equipment associated with each elevator:
(a) the driving machine
(b) motor-generator set
(d) selector
(e) governor
(f) disconnecting means (see NFPA 70, Article 620, or CSA C22.1, Section 38)
(g) the crosshead, or where there is no crosshead, the car frame, such that it is visible from the hoistway landing
(h) the car operating panel, a minimum 13 mm (0.5 in.) in height
(i) on both doorjambs of every elevator entrance at the designated level, the alternate level, the level where means necessary for tests are provided (see 2.7.6.4), and the level where an inspection and test panel is provided (see 2.7.6.5); this identification shall be a minimum 50 mm (2 in.) in height and shall be located immediately below the floor designation, where provided (see Nonmandatory Appendix E, Clause E-17)
(j) separately enclosed control components (e.g., motor circuit transformers, dynamic braking resistors, line rectifiers, or chokes)
(l) means necessary for tests (see 2.7.6.4)
(m) inspection and test panel (see 2.7.6.5)
Where any of the following devices for more than one elevator are located in the same enclosure, such devices or a grouping of devices for one elevator with demarcation to establish that all devices within the demarcation belong to that identified elevator shall be identified with the unique alphabetical or numerical identification letter(s) or number(s) of its associated elevator as assigned in 2.29.1.1:
(a) means to trip the governor and/or means to reset the governor from outside the hoistway as permitted by 2.7.6.3.4
(b) display devices or their equivalent as required by 2.7.6.4.1
(c) means to move the car from outside the hoistway as required by 27.6.4.3
(d) stop switches as required by 27.6.5.2
(e) landing inspection operation transfer switches and operating devices as required by 27.6.5.2 (see also 2.26.1.4.4)
(g) means to manually reset the ascending car overspeed detection means as required by 2.19.1.2(a)(4)
(h) means to manually reset the unintended motion detection means as required by 2.19.2.2(a)(4)
(i) the earthquake reset button or switch as required by 8.4.10.1.1(d)
