Abstract
An emergency telecommunications device that works with existing telephone lines to provide continuous hands-free two-way communication using a remote speaker with built-in microphone sensitivity that allows rescuers to use the device from a far distance. The device is activated with a pull or push of a single button activation mechanism, which instantly contacts emergency personnel who provide potentially life saving instruction to rescuers.
