We have an exterior elevator on a two-story building, required by ADA.
The required smoke detector outside the elevator door, installed under the soffit overhang, will quickly fill with dust/dirt. Any thoughts about using a heat detector at this spot that ties into the elevator recall requirement? I am the AHJ. Thank you. Sent in anonymously for discussion.

We have a passenger elevator that is a traction, machine room-less (MRL).
Under NFPA 13, 2013 Edition, Section 8.15.5.2, a 'sprinkler shall not be required for enclosed, non-combustible elevator shafts that do not contain combustible hydraulic fluids.' NFPA 72, 2013 Edition, Section 21.3.6 states that 'smoke detectors shall not be installed in unsprinklered hoistways unless they are installed to activate the elevator hoistway smoke relief equipment.' I believe these would apply to this elevator. Does the elevator only require lobby smoke detectors, including first floor for recall and second floor for alternate recall? Is a smoke detector actually required within the shaft? This is my first MRL elevator and I want to make sure we cover everything that's required. I would appreciate you views on this, thank you!

Do any fire department or other code officials have experience in seeing these be helpful or lead to increased fire fighting capabilities? I have not heard of any fire incidents where they've been beneficial and they're going in more often now - just would love to hear if they've been in use. Sent in anonymously for discussion. Click Title to View | Submit Your Question | Subscribe I am building out a space that has been vacant for multiple years. The space has a hydraulic elevator that travels 1 floor. There is a sub that is ushering the elevator contractor through the certificate milestone with all the adjacent trades.
He has proposed to change out the Class III-B hydraulic fluid with a Hydro-Safe or equivalent non-combustible fluid in order to work around the NFPA 13 requirement for a pit sprinkler and pit detection to be installed. My question is, does swapping the petrol-based fluid to a bio-equivalent have any long-term effects on the pump, pistol, seals, gaskets, etc.? Also, how do I make sure this is the fluid that remains in use for the life of the certificate? Sent in anonymously for discussion. Discuss This | Submit Your Question | Subscribe In NFPA 13 (2007 Edition) Section 8.15.5.5 is the term "passenger elevator" specifically different from a Freight Elevator?
NFPA 13 Section states that sprinklers are not required for noncombustible hoistways where the car enclosure meets ASME A17.1, but it states specifically "passenger elevators". Does this mean that a hydraulic freight elevator will definitely need a sprinkler at the top and at the bottom of the shaft? Sent in anonymously for discussion.

Posted anonymously for discussion. Discuss This | Submit Your Question | Subscribe We have a machine room-less elevator where the motor is located on top of the elevator cab and the elevator equipment is located within the elevator shaft.
NFPA 13 (2016) 8.15.5.3(2) allows sprinklers to be omitted from the hoistway of "traction elevators" where the hoistway is "protected by smoke detectors, or other automatic fire detection installed in accordance with NFPA 72", and several other requirements. NFPA 72 (2016) 21.3.3 states that only the elevator hoistway and elevator lobby smoke detectors or other automatic fire detection (as permitted by 21.3.9) shall be used to initiate Phase I Emergency Recall Operation. NFPA 72 (2016) 21.3.9 states that if "ambient conditions prohibit installation of automatic smoke detection" that other automatic fire detection initiating devices shall be permitted. What type of ambient condition in an elevator shaft would qualify as prohibiting smoke detection? I understand smoke detectors in elevator hoistways can cause nuisance alarms (NFPA 72 2016 A.21.3.9) and are very difficult to test and replace within elevator shafts, so in my opinion a heat detector would be better for elevator recall in the shaft if it's allowed by code.
