Hills, NetworX and DAS are marketed under different brands but are essentially the same alarm. These are good alarms, easy to use and usually give reliable service. To keep your alarm in top working condition the alarm should be serviced and the back up battery replaced at least every 4 years. Unfortunately many of these alarms were poorly installed years ago by companies working under the “free alarm with expensive monitoring contract” deals.
However the alarm itself is rugged and reliable.It can be monitored through a phone line,to either a monitoring station, or programmed to call your cell phone. Remote controls (key fobs) can easily be added as can wireless sensors. The alarm self monitors many faults and if a fault is present the Keypad will beep quickly when armed or disarmed or a service light will be on, indicating the alarm Needs attention.
