TDLR QEI BULLETIN 10-01-07 Determining the Designated and Alternate Landings
October 1, 2007
Good Afternoon All. I had a great question from a local fire marshal this morning. I thought I'd share the answer with you. Please see the following e-mail I sent the fire marshal regarding who and how to determine which floors are to serve as the designated landing and alternate landing. TDLR supports the authority of the locality to determine the best location that serves their needs.
In most cases, the location of these landings is self evident. If there are any questions regarding which floors are to serve as these landings, the inspector shall require the installing contractor to obtain a determination from the local fire authority and provide documentation to that effect.
If I can help in any way regarding this matter, please do not hesitate to contact me.
Y'all be Safe Out There,
Good Morning Sir. This will confirm our conversation of this morning related to the designated and alternate landings for firefighters' Phase I recall. ASME A17.1-184.108.40.206.1(a) requires a 3-position Phase I switch at the designated level. 220.127.116.11.6 requires the car to return to the designated level. 18.104.22.168.3 requires the car to return to the designated level. Several other places in 2.27 require the car to return to the designated level and/or alternate level.
The definition of designated level and alternate level from ASME A17.1b-2003 is as follows:
designated level: the main floor or other floor level that best serves the needs of emergency personnel for firefighting or rescue purposes identified by the building code or fire authority.
alternate level: a floor level identified by the building code or fire authority, other than the designated level.
It is incumbent on each elevator installer to verify, with the local fire authority, the location of the designated and alternate levels. The authority to determine where is the best location to serve the needs of emergency and firefighting personnel lies with the local fire authority.
If I can be of any further assistance, please contact me any time.
