Interlogix Simon XT User Manual 600-1054-95R-11 and 600-1054-95R-11-CN.
The Simon XT uses wireless technology to warn your family about intrusion, carbon monoxide and fire. The system communicates with a central monitoring station and sends voice messages to an offsite phone.
The security system uses sensors that communicate alarms to the control panel using radio waves. The system is supervised, meaning that the panel checks the status of each sensor to detect problems. If the panel detects trouble, it will notify you with displayed and spoken messages, beeps, and indicator lights on the panel itself.
