ABSTRACT:
A simple, inexpensive device for automatically dialing an emergency number in response to a signal generated by a smoke alarm or other security system. The device includes a cam and cam follower, arranged in combination with an electrical switch connected to a telephone line, so that the motion of the cam follower causes the switch to create a dialing function without human intervention, and without electrical power, other than the dial-tone voltage from the telephone line.
