TUG Elevator Emergency Mode

The Aethon system includes an elevator interface panel, mounted near the
elevator controller cabinet, which allows the TUG to monitor various signals from
the elevator controller. One of these signals is the Fire Service signal. By
monitoring the Fire Service signal, the TUG is able to react immediately to a fire
emergency situation by traveling to a predetermined safe parking location that is
out of the direct path needed by emergency personnel.

The following process illustrates what happens when there is a fire emergency:

(1) The fire service signal from the elevator controller to Aethon’s interface

panel becomes active.

(2) The Aethon interface panel immediately sends the TUG a message placing

it into emergency mode.

(3) If the TUG is already inside the car, the TUG will pull up to the door and

wait for it to open. When the door opens, the TUG will drive to the
emergency parking location.

NOTE: The TUG will exit when the door opens whether it opens on the
primary recall floor or an alternate recall floor.

(4) If the TUG is waiting to board the elevator, the TUG will simply drive to the

emergency parking location.

(5) When it reaches the parking location, the TUG will cancel its delivery and

notify the Aethon helpdesk of the emergency situation.

The following diagrams depict example TUG paths (blue line) to the emergency
parking location (EPark) when it is placed in emergency mode.
