ABSTRACT:
An elevator cab fire extinguishing system is carried by an elevator cab and is arranged to discharge a non-toxic fire extinguishing agent into the interior of the elevator cab in response to a fire in the elevator cab to extinguish the fire quickly and without harm to passengers and property present in the elevator cab, and includes controls responsive to the discharge of the fire extinguishing agent for automatically shutting down the ventilation fan of the elevator cab, sounding an audible alarm, and delivering the elevator cab to a designated egress level in the building within which the elevator cab travels.
