Vista20P hi 300x259The Control Panel is the “brain” and “head-end” of your intrusion/security/alarm system. United Systems installs the highest quality Control Panels with user-friendly features and ample, expandable zone capability to accommodate your needs. This is very important when you purchase your alarm system! We program your system’s devices to insure that accurate and precise information is sent to our Monitoring Center when an alarm occurs. This allows our Monitoring Center to tell you from which device or devices a signal or signals originated. With the proper zoning, we can track signals from multiple devices to help verify an event and give you more information. Your United Systems’ consultant will design your system giving consideration to: how many authorized users, zones, partitions and events your system Control Panel must accommodate. They will select the right Control Panel for your specific needs.
