Our roots in fire protection are extraordinarily strong and deep, reaching all the way back to the late 1800s. Today we serve over one million customers in the United States and Canada, providing a comprehensive array of fire alarm, fire sprinkler, fire suppression, integrated security, sound and communications, and nurse call systems and services. We deliver our industry-leading solutions in buildings and environments where life-safety protection is absolutely vital - from schools, universities and hospitals to commercial properties, industrial buildings and government facilities. Unlike manufacturers who rely on independent dealers, we serve customers directly, through a network of 150 company-owned offices. In everything we do, SimplexGrinnell strives to keep people and property safe.
