Life Safety - Any type of security system or security system monitoring that is meant to protect one’s life instead of property. Fire alarms, panic buttons, or medical alert systems are all examples of life safety systems.
Line Seizure - Your alarm system has priority access to your phone line and can interrupt telephones, modems, or answering machines to send a signal. “Line seizure” means that your alarm panel will disconnect these secondary devices if the alarm has been triggered or for whatever reason has to send a signal to the central monitoring station.
Low Tempurature Sensor - A security system device that sends an alarm when a preset low temperature is reached.
