INSTALLATION─DONE RIGHT


At Marran, we know that every home, and every person, is different, so we don't install a cookie cutter alarm system. The placement of alarm sensors and the system programming can mean the difference between a secure home or business and one which is vulnerable to burglaries, so we ensure that our technicians are the best in the business.  Our basic package provides a level of protection that exceeds that provided by other companies, but we provide upgrades and add-ons to suit your individualized needs.
