A telephone system includes a user-carried emergency communication system in combination with a cellular telephone. The user-carried handset has a large button on a first face. Pressing the button summons help by automatic connection to the 911 emergency telephone network. It also activates a signaling device mounted on the inside glass surface of a window that illuminates a message that 911 has been called. It may also sound an alarm. A pre-recorded massage may also be sent to the emergency call center. The other face has the functions of a cellular telephone. All elements are within the building, with installation by simply plugging cords into power outlets the same as any cellular phone and mounting the signaling device with suction cups. There are no monthly fees except for the usual cellular phone fee. |
