"Don't marry your alarm company," Advanced Systems declares, and while there's very little chance of that actually happening, their approach to alarm-system monitoring does inspire a more easy-going partnership. These pros monitor all the top systems—be they Honeywell, DSC, or GE—with the same industry-wide procedures: When they're alerted by an alarm system, they first call the premises, followed by a designated call-list, and then the appropriate agencies. The company's no-contract monitoring policy works with new or existing security systems, allowing clients to decide when they're in and when they're out.
