Security Lock (Outward Opening Door)

Outward opening doors have an optional key locking mechanism, accessible from
outside the bus. A key operated bolt slides into a hole in the header when the door
is in the closed position and locked. This option also requires use of the hinged stop
on the door control.

Emergency Door Vandal Lock

The emergency door and the rear emergency window may have an optional vandal
lock feature, which prevents entry through the emergency exit. There are two types
of locking mechanisms; a Cylindrical Key Lock and a Sliding Bolt Latch lock. These
locks will prevent the emergency exit from being opened from the outside.
The bus will not start if an emergency exit is locked. An audible buzzer will notify
the driver of the locked condition. The Cylindrical Key Lock type mechanism can be
unlocked by using the key to remove the cylinder and placing it in the receptacle at
the side of the door. For the Slide Bolt Latch lock, simply move the latch to the unlock
position. Unlocking the exit in this manner will activate a microswitch which will al-
low the bus to start. If a lock is activated while the engine is running, an alarm will be
activated in the exit and driver's area.
[WARNING] The bus must not be operated with the emergency exit locked.
