First Claim
1. An alarm system to remind a driver to inspect a bus for remaining passengers, the bus having an ignition switch with an on and an off position, the alarm system comprising:
- an electrical circuit arranged to effect a resting state in which the alarm system is unpowered and inoperable, a stand-by state when the ignition is in the on position, an armed state in which the alarm system is activated, and a disarmed state in which the alarm system is deactivated but energized such that the system can be returned to the armed state, whereby the disarmed state can be achieved with the ignition in the on position;
an alarm to indicate an alarm state; and
a deactivation switch positioned at a rear of the bus to remove the alarm system from the armed state or the alarm state.
