Abstract: A portable room safety security system for use in hotel rooms, apartments, vehicles having sleeping areas (such as motor homes, RV's, trailers, etc.) and the like. The system integrates into a single housing a smoke detector and a movement sensor, both serially connected to an audio alarm and a visual alert. The system further includes a magnetically isolated slot for holding hotel key cards, as well as a series of hooks for holding several key rings. Also available is a bracket mounted to the housing for holding a flashlight. The system is optionally operated using a remote control device, and may include circuitry enabling automatic telephone dialing to alert outside assistance in the event of an alarm. Two types of structure may be used to suspend the device from an associated door. The first is a pliable extension bar and hook which suspends the device from a door knob. The second is a bracket extension piece enabling the device to be hung from the top of a door.
