ABSTRACT:
The present invention is a battery powered, portable microprocessor based early warning alarming smoke detector. It provides the user two different time limited unattended alarms, as well an alarm for a tipped smoke detector; an alarm for a bumped smoke detector; an alarm based on nearby or lower elevation smoke by either of the two smoke detection devices; and a low power alarm. It offers “full protection” for most of the likely scenarios encountered by residential users that could result in a fire. Since the device is microprocessor controlled, the timing intervals and magnitude of the different alarm notifications can be preprogrammed as well as the sensitivity of the smoke detector devices.
