The proprietor of a locally owned alarm installation and monitoring company says he has the answer to the plague of false alarms that law enforcement agencies respond to. In fact, he says the technology to defeat false alarms has been around for 10 years.

Roger Score, owner of Tucson Alarm Company, one of the few remaining locally owned alarm monitoring services in the region, has been in business since 1984 and is licensed by the state to perform both commercial and residential alarm installation and monitoring. Score maintains the technology that would do away with the vast majority of false alarms from both residential and commercial alarm systems is already built into existing and newly installed security panels.

"We're the only company in town that sells a cross-zone system, but all current security panels can be programmed to do cross-zone," Score said. "A cross-zone alarm requires two different zones to trigger within a 10-minute window of each other in order to cause an alarm, instead of a single zone. This is not new technology - it's 10 years old and has been sold in Tucson since 1984 when the City of Tucson made cross-zoning a part of its alarm ordinance."

When Score installs motion detectors as part of an alarm system, he puts in a minimum of four motion detectors and requires at least two of them to trigger in the 10-minute period in order to send an alarm signal.
