ABSTRACT:
A smoke detector system having a base unit and multiple satellite units is provided. The base unit detects various hazards, i.e., smoke or carbon monoxide, and broadcasts a radio frequency signal to activate warning devices on the various satellite units. The satellite units include a radio frequency receiver to receive the signal broadcasted by the base unit. The warning devices include a laser cannon, a speaker, a strobe light, and a wireless camera separately or in combination with other warning devices. Alternatively, each base unit may include one or more of the warning devices and a radio frequency receiver, and each satellite unit may include the detection devices and a radio frequency transmitter. In this way, each device in the system may activate warning devices in each other device in the system when a hazard is detected.
