Abstract: A programmable emergency communication system for dialing an emergency number, such as a number for a central station, a 911 exchange, or third parties, permits voice-to-voice communication between a home system and the called number. The home system automatically dials one of the stored telephone numbers in response to a signal from a hand held medallion, a signal from a sip/puff switch, a signal from a paddle switch, a signal from a smoke detector, or a signal from a front panel of the home system. The home system reports emergency signals and also reports non-emergency signals, such as a low battery condition, to the central station. The home system has many options which may be programmed to suit the particular desires of the user. The home system may be programmed by any telephone which has access to the telephone line to which the home system is connected.

Abstract: A vandal resistant, remotely programmable voice communications unit is capable of being programmed for automatically calling predetermined telephone numbers. The unit is programmed remotely from any touch-tone telephone. A vandal-resistant push-button actuator employs first and second axially spaced apart, slidable seals on a push-button mounted within a housing. The seals absorb transverse blows to a raised portion of the push-button and a lubricant is disposed between the seals to prevent an adhesive inserted by a vandal from disabling the actuator. A speaker and microphone baffle utilizes offset passageways to inhibit the introduction of a pointed object therethrough to prevent damage to the speaker or microphone. A raised push-button actuator is disposed inwardly of an escutcheon and shaped to form a concave, ring-shaped surface therewith, thus to inhibit damage to the inner surface of the escutcheon from a hammer blow.

Abstract: The present invention is directed to a telephone line seizure circuit which may find particular application in home security systems which feature an automatic dialer which automatically sends an alarm detection signal out on a telephone line when an alarm condition is detected. The telephone line seizure unit of the present invention operates so that when the automatic alarm dialer is on-hook, the telephone line seizure units are transparent to the telephone system and the telephones can then be used normally. When the automatic alarm dialer goes off-hook, then the telephone line seizure unit operates to disconnect any telephone in use connected thereto, which will thereby allow the automatic alarm dialer to go back on-hook briefly, and after about 30 or so to go off-hook, to thereby utilize the telephone line to send out the alarm detection signal.

The base unit deciphers the coded signal and automatically contacts a central monitoring station via a telephone link. The base unit sends the serial number of the base unit, and the specific condition requiring attention, i.e.

Abstract: An electronically-operated gun safe which has an telephone system that establishes an interactive telephone contact with law enforcement authorities when the gun safe is opened with an emergency key word. A non-emergency key word allows the gun safe to be opened without establishing a telephone contact with law enforcement authorities. The telephone system provides an alarm when the gun safe is disconnected from an external telephone wire without first opening the gun safe with the non-emergency key word. A 9-1-1 key word allows a telephone contact to be established without opening the gun safe. A master key word allows the gun safe to be opened if the emergency key word is lost or forgotten. The gun safe is locked out for a time period when successive incorrect key words are attempted and a tamper display alerts an owner that an unauthorized entry has been attempted.

Abstract: Hardware or software is added to a local system that has incorporated therewith a modem that is normally connected to the switched telephone system to initiate surreptitious calls to report various data to a remote monitoring station. These reporting calls are made from the remote equipment to one or more monitoring sites. The call initiation is preferentially triggered at a carefully controlled semi-random rate, perhaps once a week. The exact time chosen is concealed from the operator of the system that is reporting to the monitoring site. The same modem, or modems, normally used by the local system being monitored is (are) also used for an outgoing data call to ensure that the telephone connection is always accessible to the monitoring apparatus. For voice mail systems which lack modems, DTMF (Touchtone) can be used to transfer data.

Abstract: Described is an automatic paging system that will alert a paging service subscriber to the occurrence of specific events at a remote location using a standard home type answering machine and/or a standard alarm system. The paging system works in conjunction with existing paging subscription services and answering machines presently available. The system detects if a valid message has been left on the answering machine or if an alarm has been tripped, then dials a number that the user programs into the system that corresponds to the paging service telephone number, then waits for an acknowledgment tone from the paging service and dials a distinct code that corresponds to what has occurred at the remote location. The system will forward a telephone number to the paging service subscriber, if such a number has been entered into the answering machine by a caller.

Abstract: A door phone controller has a door ajar feature for alerting a user that a door was left open. The door phone controller accommodates the door ajar feature in several different ways depending upon how it is configured to interface with the central office line. If the door phone controller is configured to interface with the central office line as an individual station, then when a door is left open, the controller alerts the user via auxiliary alert contacts specifically provided for activating a customer chime. When the door phone controller is configured as a ring-down station, the door phone controller alerts the user that the door was left ajar by dialing a pre-programmed telephone number and sending a door ajar tone. If the door phone controller is configured as an interface with a trunk port, then when the door is left open, the controller alerts the user by ringing the trunk line and also energizing the auxiliary alert contacts.

The telephone number may be a single specified digit, or a multi-digit number stored in a last number dialed memory of the dialer circuit. After dialing of the telephone number, the audio signal is supplied to the telephone line regardless of whether an answer occurs at the remote end. After a predetermined time interval, a timer circuit releases the telephone line, waits a predetermined time interval, causes the telephone number to be dialed again, and then causes the audio signal to again be applied to the telephone line.

Abstract: An emergency alerting system for alerting or warning large numbers of people of the occurrence or threat of an emergency using available communications media. Multiple facilities are monitored for the occurrence of multiple alarm conditions. On the occurrence of such a condition radio or telephone contact is made with a Local Emergency Planning Committee (LEPC) and the LEPC is notified of the site and nature of the alarm condition. Using a predetermined listing or data bank the LEPC selects a number corresponding to the site and condition and transmits such number to an automated controller for a radio transmitter. The transmitter may be part of an existing radio paging system. The automated controller, on the basis of the number dialed in by the LEPC, transmits an appropriate Code Assignment Plan (Cap Code) signal. The Cap Code signal is the electronic signature of a preprogrammed Cap Code chip within individual radio receivers positioned at the sites of intended alarm recipients.
