What's the elevator got to do with it?

by Adam Jacobs 9/21/2022

Again today we got to the end of a project and sure enough, the installing electricians had zero notice from the general contractor that there would need to be an elevator inspection for fire alarm function.  In the state of Iowa, there is a totally separate elevator inspection done by the state.  These inspectors focus only on the elevator function, elevator safety, and related safety issues.  This may not be the case in all states.  The fire alarm is supposed to control the following functions:


Primary Floor Recall

Secondary/Alternate Floor Recall

Shunt Trip

"Hat" light in car

Smoke Damper (many AHJs also want this to have manual override)


These may not all be required in all jurisdictions, but most want all 5.  These functions are only triggered by the elevator lobby smoke detectors, which are required to be within 21' of the elevator door (center) in the same smoke cavity/space.  So if there are fire doors that separate a corridor from the elevator lobby, you can't use the hallway smoke as your elevator lobby smoke because the header is likely more than 12".


Just remember, think about the elevator when you plan the project.  You'll need extra parts and extra time to make sure this important people transport is as safe as can be.
