Combination cordless telephone and premise-monitoring alarm system
DCFirst Claim
1. A combination cordless telephone and premise-monitoring alarm system, the combination comprising:
- a base unit, a cordless handset, and, at least one remote sensor for generating data in response to a given alarm event;
the base unit including a telecommunications interface for establishing a telecommunications link with a public switched telecommunications network (PSTN), a radio interface for establishing a radio link with the handset, a data interface for establishing a data link with the remote sensor, and, processor circuitry for processing intercommunication of control and message data among the interfaces;
the handset including a radio interface, a keypad, a speaker, a microphone, and processing circuitry for processing intercommunication of control and message data among the radio interface thereof, the keypad, the speaker and the microphone;
the remote sensor including means for completing the data link between the remote sensor and the base unit;
wherein the processing circuitry of the base unit further processes alarm system functions such as monitoring the data link for data of the given alarm event and, in response thereto, transmitting control and message data via the telecommunications interface to a central alarm-monitoring station.

Abstract
A combination cordless telephone and premise-monitoring alarm system has a base unit, a cordless handset, and one or more remote alarm detectors. The alarm detectors can be generally either smoke detectors, motion detectors, or open-entry detectors. The base unit includes at least one interface for the public telephone network, and another interface for radio communication with the cordless handset. The base unit preferably also communicates with the remote alarm sensors across the same radio interface. The base unit includes telephone call circuitry to relay telephone calls between the public telephone network and the handset. The base unit also includes alarm processing circuitry to send an alarm warning to a central alarm-monitoring station in response to an alarm signal from a remote detector. The base unit has control circuitry that is configured such that if, during a telephone call, the base unit is given an alarm signal, the base unit will either (i) hang up the telephone call and call up the central alarm-monitoring station to give warning, or (ii) call up the central alarm-monitoring station on a second telephone line (if available).

9. A combination cordless telephone and premise-monitoring alarm system, the combination comprising:
-
a base unit; a cordless handset; and
,at least one remote alarm sensor; the base unit including a telecommunications interface for establishing a telecommunications link with a public switched telecommunications network (PSTN), a radio interface for establishing a radio link with the handset and the remote sensor, and, processing circuitry for processing intercommunication of control and message data between the telecommunication and radio interfaces; the handset including a radio interface, a keypad, a speaker, a microphone and processing circuitry for processing intercommunication of control and message data among the radio interface thereof, the keypad, the speaker and the microphone; the remote alarm sensor including a radio interface and means for (i) generating data in response to a given alarm event and (ii) transmitting the data of the given alarm event across the radio link to the base unit; wherein the processing circuitry of the base unit co-processes sensor data and handset data to allow concurrent use of the radio link among the base unit, handset and remote sensor so that traffic on the radio link between the handset and the base unit does not block traffic between remote sensor and the handset. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A base unit for a combination cordless telephone and alarm system, the base unit comprising:
-
an interface for a public switched telecommunications network (PSTN); a radio interface for forming a radio link among a cordless handset and a remote alarm sensor; aural-signal processing circuitry connected between the radio and PSTN interfaces to process telephone call message and control data; alarm data processing circuitry connected between the radio and PSTN interfaces to process alarm message and control data; wherein, during a telephone call, when the alarm data processing circuitry receives a message of the occurrence of given alarm event from the remote alarm sensor, the alarm data processing circuitry is configured to issue a given set of instructions to the PSTN interface chosen from (i) a set of instructions which cause interruption of the telephone call and then transmission of a message to a central alarm-monitoring station, and, (ii) a set of instructions which cause transmission of a message to the central alarm-monitoring station over a PSTN path other than a PSTN path used by the telephone call. - View Dependent Claims (18, 19)
