Title: Cordless telephone system

Abstract: A cordless telephone system including at least a first cordless base and a first handset, wherein either or both of the cordless base or the handset further contain a wireless receiver for receiving signals from at least one wireless sensor. The wireless sensor sends its wireless communications in a different frequency band than is used by the cordless telephone system. This cordless telephone system is typically based upon the same architecture and same components as a security system or security network described in cross referenced applications, but the product packaging appears in an embodiment that is more familiar to users as a cordless telephone system. The wireless sensors can be in several example forms such as intrusion sensors, which are used for example in perimeter monitoring or motion sensing, fire or smoke sensors, glass breakage sensors, or temperature sensors.
