Wireless home fire and security alarm system

A low power sense and/or control system implemented with wireless two-way communication capability in a communication medium between a base station and one or more of multiple sensor devices distributed at different locations throughout a spatial region, comprising:

• multiple sensor devices each having a different identification address and a sensor device transceiver that transmits a communication message signal in response to a wake-up producing condition, the sensor device transceiver including low power-consuming sensor signal processing circuitry and sensor signal communication circuitry selectively switchable between a lower power-consuming standby mode and a higher power-consuming operating mode, and the sensor signal processing circuitry storing in memory sites different control signals corresponding to different communication message signal producing conditions;
• and
• a base station having a base station transceiver including base station signal processing circuitry and base station signal communication circuitry, the base station signal processing circuitry cooperating with the base station signal communication circuitry to receive the communication message signal and transmit in response to it an activation signal to which the sensor device transceiver of the sensor device that transmitted the communication message signal can respond to produce a control signal corresponding to the communication message signal producing condition, and the base station receiving from the sensor device transceiver that transmitted the communication message signal a supervision message that includes the identification address to verify a communication link between them.

A method of automatically programming a wireless sense and/or control system to enroll one or more sensor devices distributed at different locations throughout a spatial region, comprising:

• providing a two-way wireless communication capability between a base station having a base station transceiver, an intervening sensor device having an intervening sensor device transceiver, and at least one of the sensor devices having a sensor device transceiver that is out of direct communication range with the base station;
• initiating an enroll condition in the base station to place the system in a sensor device enroll mode;
• introducing a trigger event to the sensor device and delivering from the sensor device transceiver, through the intervening device transceiver, to the base station transceiver in response to the trigger event a new device message signal identifying the sensor device;
• delivering from the base station transceiver, through the intervening device transceiver, to the sensor device transceiver in response to the new device message signal a programming signal indicating a sensor device address;
• and
• storing the sensor device address in the sensor device.
