Abstract
The invention is for a vandal resistant latch/starter-interlock assembly for a bus door. In the assembly of the invention, the alarm and the starter-interlock are part of the same assembly. The assembly includes box through which a modified latch bolt extends laterally. The latch bolt is locked by a vandal lock. When unlocked, the latch bolt slides or moves to allow the door to be opened. The alarm and starter-interlock are activated after unlocking the vandal lock. Typically, the alarm is activated when the latch bolt is moved, usually by moving a door latch. While the starter-interlock can also be activated by moving the latch bolt, it is preferably activated by unlocking the vandal lock.
