Someone just asserted to me that elevator coordination needs to be to 0.01 seconds (i.e. need to rely on manufacturer's tested combinations) regardless of whether or not the elevator is considered to be or required to be on Emergency power. So, e.g. a low rise building, say 3 stories high, where the elevator is not necessary for the evacuation of people. Here the elevator does not need to be on Emergency but this guys telling me that as per NFPA 620 it needs to coordinate to the higher standard required otherwise per Article 700 of the NEC, namely 0.01s
Is it true?
