ABSTRACT:
An emergency telecommunications device comprising a telecommunications control circuit having an automatic dialing circuit preprogrammed to dial 911; a digital-to-analog voice circuit to transmit one of three predetermined messages to an emergency operator when the control circuit is activated by one of three activation buttons: a medical emergency activation control button, a fire activation control button, and a police activation control button; and a touch tone decoding circuit that allows an emergency operator to play first and second user programmable messages and to control various functions of the telecommunications device. The fire, medical emergency and police control activation buttons are normally covered by a pivoting lid member. Closure of the lid member actuates a device activation control switch. When the lid member is in a fully closed position the telecommunications device is in the OFF state. When the lid member is in a partially or fully open position the telecommunications device is the ON state.
