Door Override (SWAT) Switch
The door override switch, located at the access door on the upper-right-hand corner of the rear engine
door, will wake up the I/O system (if it is in sleep mode) and activate both door motor solenoids to
open both the front and the back doors. Unlike the door control handle on the driver’s console, this is a
maintain switch, not a momentary switch. When switched to the open, the doors will stay open until you
switch back to close them.
Sensitive Edge Strip
The mating edges of most rear doors have sensitivity strips that will activate a microswitch if an object,
or part of a passenger’s body, is pinched between the doors as the doors close. If this happens, the door
operation will be reversed to the open direction, thus freeing the obstruction. The two rubber door edges
are sealed and connected to two air switches that activate the sensitive edge system to electrically open
the door in the event of an obstruction. The pressure on the edges forces air inside the edges into a tube
running from the edges to the switch, which activates the motor to open the door again.
The sensitive edge system is maintenance free and requires no adjustment. It does, however, require
frequent inspection and testing.
Routine (Daily) Inspection
Verification of sensitive edge system functionality should be performed on a daily basis. This is a simple
test that requires very little time and should be performed before a bus leaves the depot for transit ser
-
vice. Before leaving the depot, drivers should first authorize the exit door system via the door controller
and then physically squeeze each sensitive edge by applying minimal force (5 to 10 pounds) to verify
that the doors will cycle open and/or trigger audible alarm.
quarterly Inspection
The edges should be tested for proper functionality once every three to four months in the following
manner:
california highway patrol obstruction sensing test
Authorize and open the doors. Place a 1" diameter solid rod (cylinder) at roughly the center of the clear
door opening. Command the doors to close. When the sensitive edges encounter the rod during the clos-
ing cycle, the doors should recycle open and/or an audible alarm should sound. The doors should not
close on the rod without detecting it as an obstruction. This test should be performed at various positions
along the sensitive edge, preferably, near the top, middle and bottom. Please note that the edges may not
sense an obstruction inserted approximately 1 1/2" from the very top or very bottom of the edge.
cylinder extraction test
With bus power off, open the exit doors and insert a 1.5" diameter smooth rod (cylinder) near the center
of the clear opening and allow the door edges to close over the cylinder. Using a force gage attached to
the rod, pull the rod out from in between the edges. The maximum force measured should not exceed 35
pounds.
