    An elevator inspector is questioning whether the sump alarm is permitted in the hoistway.

    In reference to the below information and other that you may have what is your determination?

    The plumbing code is silent on where the alarm should be located. But an elevator code interpretation (10-1493) could be interpreted unrelated devices in the hoistway.

    2.8.1 Equipment Allowed

    Only machinery and equipment used directly in connection with the elevator shall be permitted in elevator hoistways, machinery spaces, machine rooms, control spaces, and control rooms.

    2.8.2.2 Only such electrical wiring, raceways, and cables used directly in connection with the elevator, including wiring for signals, for communication with the car, for lighting, heating, air conditioning, and ventilating the car, for fire detecting systems, for pit sump pumps, and for heating and lighting the hoistway and/or the machinery space, machine room, control space, or control room shall be permitted to be installed inside the hoistway, machinery space, machine room, control space, or control room.

    Inquiry 10-1496

    Subject: ASME A17.1-2007, Requirement 2.2.2.5 and 2.8.1

    Concerning sump pumps in elevators equipment allowed in machine spaces

    Question (1): Would it be an acceptable interpretation to classify the electrical disconnect and control panel for the sump pump as being used directly for operation with the elevator, thus permitting the disconnect and control panel to be located in machinery spaces, machinery rooms, etc.?

    Answer (1): No.

    Also contrary to what the plumbing commentary alleges it has always been the intent that the alarm device should not disable the required pump; this language added to the 2015 IPC.

    Note in reference to the above, the plumbing code did not have this exception until the 2006 edition;

    Edition: A17.1-2000 through A17.1-2007 including A17.1a-2008

    Exception: An oil separator is not required in hydraulic elevator pits where an approved alarm system is installed. Such alarm systems shall not terminate the operation of pumps utilized to maintain emergency operation of the elevator by firefighters.

    Have the Elevator Inspector provide you with acceptable,
    cited codes & sections, for your review.

    The elevator sections and its official interpretation apparently allows only a cord plugged sump pump in lue of a drain.

    As we are aware though often quoted for guidance the commentary code and as demonstrated here was incorrect. Granted official interpretations have been wrong too.

    Would prefer to substantiate the decision on where this alarm is approved that aligns with a specific elevator code with the plumbing (or an electrical) alarm code not because I say so.
