Abstract: An alarm system that couples into a telephone system serviced by Touch Tone.RTM. equipment or Touch Tone.RTM. equipment intermixed with digital dialing and which when actuated automatically dials a telephone number and delivers a message into the receiver of the telephone whose number has been dialed. The alarm system is made up of two parts, an emergency transmitter unit and a receiver-dialer unit. The emergency transmitter unit includes a small battery powered radio frequency transmitter. The receiver-dialer unit includes a radio frequency receiver, a magnetic tape transport and a coupling device for coupling the unit into a telephone voice pair. The magnetic tape transport contains a magnetic tape on which is recorded a series of audio frequency tones corresponding to the Touch Tone.RTM. combinations of the number to be dialed and a message which is to be delivered. When the emergency transmitter unit is activated it sends out an RF signal which is received by the receiver-dialer unit.
