All of Mule Security’s accounts are monitored by Centra-larm Monitoring. Centra-larm is a U.L. listed monitoring station located in Manchester, New Hampshire. Centra-larm serves only the New England states. By limiting the geographic area it serves, Centra-larm is able to form close relationships with dealers. We chose Centra-larm after meeting with the owner, Stu Helmig, and the rest of the staff and seeing first hand their commitment to personal customer service.
