Signal One Fire and Communication

Acquired: 2016


Signal One Fire & Communications was founded in June 2003 by John and Paul Grako. They were purchased by APi Group, Inc. in 2012 and acquired by WSFP in January 2016. Signal One Fire & Communication expanded our fire alarm, security, CCTV, and special hazard services in the Arizona market. Signal One also brought a large monitoring and inspection base with them that has helped to strengthen these markets within WSFP.

We service all customers from residential to industrial facilities with installations, service calls, maintenance and monitoring.
