We realize that there are systems that are ten, twenty, thirty, or more years old that are still in service, protecting lives and property. We also know that it is difficult to get help when trying to service or test one of these systems. We can help. Call or email us with any questions you may have. In addition we can source parts for many legacy systems, or lead you in the right direction to use newer parts, if necessary. These are life safety systems and their failure puts a tremendous burden on the facilities and those responsible for them. Contact us if you need help or have questions. We can and will provide assistance to the best level of our capabilities.
