The Allegro DTIM security system from GE Interlogix provides added security by physically separating the telephone interface from the control panel. What distinguishes the Allegro from other security systems is the physical separation of the control panel and telephone module, the dialog telephone interface module (DTIM). The DTIM is a battery-operated communication link between the control panel and the central monitoring station. It receives radio signals from the panel, and then uses the phone line to report security events to the central monitoring station. If the panel is damaged during a break-in or fire, the DTIM can still report to the central monitoring station. Physically separating the DTIM from the panel also ensures that the panel can be placed in the most convenient position for the resident.
