Abstract
An apparatus for emergency dialing and oneway communication by telephone includes an autodialing circuit for dialing a preselected emergency telephone number. The circuit is activated by a switch and provides communication of audio information from the vicinity of the device to an emergency services operator during an emergency situation such as a criminal assault of a convenience store. The apparatus is characterized by the presence of a microphone, and the absence of a speaker connection for transmitting the voice of the emergency services operator. In this manner, the criminal assailant is not made aware that police have been contacted.
Claims3
An apparatus for emergency dialing and one-way communication by telephone comprising:
- a telephone dialer circuit for dialing a preselected emergency number and establishing a telephone line connection;
- a microphone connected to said telephone dialer circuit for sensing and transmitting sound from the vicinity of the microphone upon the telephone line connection being established;
- manually operable switch means electrically connected to said telephone dialer circuit for activating said circuit and causing the dialing of the preselected emergency telephone number on a telephone line to contact an emergency services operator;
- and
- said apparatus being characterized by the absence of a connection to a speaker during all periods when a telephone line connection is established so as to preclude audio communication from the emergency services operator.
An apparatus for emergency dialing and one-way communication by telephone comprising:
- a housing adapted to be mounted in a concealed location accessible to a user;
- an emergency switch mounted to said housing;
- a telephone line connection jack mounted to said housing;
- a telephone dialer circuit mounted n said housing and connected to said emergency switch and said telephone line connection jack for dialing a preselected emergency telephone number and establishing a telephone line connection to an emergency services operator responsive to activation of said emergency switch;
- and
- a microphone connected to said telephone dialer circuit for sensing and transmitting sound upon establishment of a telephone line connection, said apparatus being characterized by the absence of a speaker connection during all periods when a telephone line connection is established so as to preclude audio communication from the emergency services operator.
An apparatus for emergency dialing and one-way communication by telephone comprising:
- a housing adapted to be mounted in a concealed location accessible to a user;
- a power source;
- an emergency switch mounted to said housing for, upon actuation, connecting said telephone dialer circuit to said power source and to said telephone line connection jack;
- said telephone dialer circuit having an internal telephone for establishing a telephone line connection to an emergency services operator, a preprogrammed sequencer for communicating an emergency telephone number to the internal telephone, and a timing pulse generator for providing timing to the sequencer;
- and
- a microphone connected to said telephone dialer circuit for sensing and transmitting sound upon establishment of a telephone line connection, said apparatus being characterized by the absence of a speaker connection during all periods when a telephone line connection is established so as to preclude audio communication from the emergency services operator.
