Let's start with the elevator code ASME A17.1 reference to it does not appear in 13D, nor does 13D reference 13 when 13D does not apply. So this is an area where the 13D committee needs to make some sort of a guide.
Many of the home elevators are not from Otis or Shindler or any other major MFG, and don't meet the same standards as commercial residential elevators. Many are (MRL) machine room less, with the motors on top or under the cab. There are climbers, fiction climbers and belt climbers as well as hydraulic. The smoke detector at the top of shaft is building code required, but it's not interfaced with elevator controls. Some shafts are vented, and some are not as the elevator moves slow enough to allow air to move around the cab without compressing it. Vented shafts present the freeze issue for any sprinklers. Dry sprinklers could allow for this, but they are not residential listed. Again more guidance is needed from 13D committee. Currently we protect "fueled Heat producing appliances within concealed spaces" these are not fueled, or heat producing as part of their function. If we start protecting non fueled appliances, will we then protect bathroom exhaust fans? Even if they have a heater element or infrared lamps? Small pumps, or fan coils? I think I remember something in a proposal for 13D 2010 about elevators, but I'll have to look it up. Thom McMahon, SET Firetech, Inc. 2560 Copper Ridge Dr P.O.

I'm assuming that I will need a sprinkler at the top and bottom of the elevator shaft since it is constructed of wood. The trouble that I foresee here is that there is only 18" between the finished floor and the bottom of the elevator pit. Will this give me enough room to install a sprinkler? If there is a smoke at the top of the shaft can I eliminate that sprinkler? Or, should I eliminate the pit sprinkler and keep the upper sprinkler? Or, is there another solution that someone else has used?
