This automatic feature shall be achieved by means of a pressure sensor located inside the exhaust ducting; this pressure sensor shall sense the engines output pressure upon the CITY OF ARCADIA Vehicle Exhaust System FIRE STATION 105 15650 -3 first stroke of the engine piston and energize the fan starter. The automatic controller shall use an adjustable timer to keep the contactors energized for a designated period of time.

The rail shall be securely attached to the building structure and supports a flexible hose assembly that moves with vehicle inside the station. As the vehicle nears the exit door, the pneumatic nozzle connection located at the tailpipe shall release its air pressure automatically therefore releasing the nozzle from the tailpipe.

After the system releases from the vehicle tailpipe at the door, it shall retract passively and remain near the door in a convenient storage position for ease of attachment when returning to the station. When the vehicle returns to the station, a system operator manually pulls the flexible hose assembly to the threshold of the entrance door. The system operator holds the pneumatic connection device approximately 18" from the floor and at the door threshold. Without bending over, the system operator, in order to avoid facial exposure to the exhaust gas stream, attaches the pneumatic connection device to the tailpipe at the door threshold. As the vehicle approaches the station, the driver momentarily stops. The exhaust fan motor energizes at the same time the connection is made. Standing straight up with the pneumatic fill valve in his left hand the system operator shall slide the connection device up against a flanged adapter attached to the vehicle tailpipe; the operator shall then inflate the pneumatic nozzle around tailpipe. The cycle is completed as the exhaust fan starts and vents the toxic gases with the pneumatic connection nozzle firmly attached to the vehicle exhaust pipe.
