Smoke detection methods, devices, and systems
First Claim
1. A condition detector composing:
- a sensor to provide an alarm signal upon detecting a condition;
a communication device having a unique address, to wirelessly transmit the alarm signal by formatting the alarm signal into a packet, the packet comprising a packet length indicator indicating the number of bytes in the packet;
a total packet indicator indicating the number of packets in a message; and
a current packet indicator to distinguish one packet from another packet; and
a gateway geographically remote from the communication device to receive the wireless alarm signal packet and transmit the alarm signal via a WAN to a monitoring device, the monitoring device being adapted to receive the alarm signal.

Abstract
The present invention is directed to a system and method for accessing home monitoring devices remotely via a distributed wide-area network (WAN). More specifically, the present invention is directed towards a smoke detector system, which monitors for the presence of smoke and communicates the smoke condition to a remote location. The smoke detection system comprises a smoke detection device connected to a communication device. The smoke detection device outputs a signal or a change in a signal upon detection of smoke. This signal or change in signal is monitored by the communication device. The smoke condition is then communicated to the remote central location. Other embodiments are also claimed and described.
