Where do they keep the controls for the elevator? There has to be a control box somewhere. We have run into elevators that do not have the capacity to take on fire alarm relays but then the whole elevator is typically being upgraded to bring about the addition of the relays.
Even without an elevator machine room, there is still an elevator machine. You would install the modules adjacent to the elevator controller.
Yeah, or beneath the elevator
We had a project recently with a ThyssenKrupp Endura MRL (machine room less) elevator and an Edwards EST3 FACP. The controller was built into the shaft at the lobby level, basically where the stainless steel trim would be on a normal elevator just in front of the doors. We were able to locate the control relays adjacent to the elevator shaft in a janitor's closet that was roughly 3 ft. from the controller.
If you want to email me, I would be happy to send you a sketch I made just to give you a general idea. 7UL@ORNL.GOV
The fire alarm modules should always be installed outside of the shaft. Often the controller is in a separate room, but if in the shaft they should be located immediately outside the location of the controller. In almost all cases the elevator takes a normally closed contact from the FA device, meaning it is a fail-safe interface and makes the 3' rule not applicable.
The quick answer is don't put any FA devices in the shaft that are not explicitly required by code to be in the shaft.
