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. The central station receives data from the home system and can determine the subscriber ID, the device which initiated the call, and the battery level of the device. The central station can also distinguish between emergency and non-emergency calls. A printer at the central station prints a record of all data transmitted between the central station and the home system.

Programmable emergency communication system including automatic dialer

An apparatus for interfacing a speaker phone with a telephone network includes switch means for selectively connecting said interfacing apparatus with a telephone network to permit either conventional or automatic answering. A coupler, responsive to ringing signals on the telephone lines discharges a charging capacitor to a level sufficient to cause the automatic, hands-free interconnection of the speaker phone with the telephone line. In one embodiment, a timer is provided for limiting the length of time during which the speaker phone is coupled to the telephone line. A reset switch is provided in cooperation with the timer to permit the timing cycle to be reset upon command, thereby to shorten the time of connection if desired. The system operates in either a timed or extended mode. To bypass the timer and indefinitely extend the time during which the answered call is coupled between the telephone lines and the speaker phone, an extend switch is also provided to override the timer. In an alternative embodiment, the ringing voltage on the telephone line is optically coupled to an electromechanical circuit controlled by a photocell.
