Elevator recall and shunt issues
Elevator recall and shunt issues
(OP)
Is elevator recall required on a building with just tow floors? Is elevator recall required on a buildling with a wheel chair lift? When a shunt trip for the power in the elevator shaft is tied to the smokes or heats under the temp rating for the sprinkler system does it have to be tied to the FACP and supervised or can you install heats and relays that will accomplish the shunt without the use of the FACP panel that has battery backup and supervision?

Re "Supervisory monitoring is required" -- note that even if your building does not have a fire alarm system (it may not be required to have an FACP), then you need to install an elevator monitoring panel. What is this panel? It is an FACP that is not providing any real fire alarm functionality, it's only purpose is to monitor your recall equipment.
Check out the elevator code (A17.1) for more info.
