Fire Detection & Suppression


For over 33years, DNL has utilized the latest technologies to install or upgrade trouble-free, code-compliant fire alarm systems. Systems that include all the components of a fire detection or suppression system such as:

  1. Control Panels
  2. Pull Stations
  3. Horn Strobes and Speakers
  4. Smoke and Heat Detectors
  5. Central Station Monitoring
  6. Automatic Sprinklers

Our in-house design experts will handle everything from code-compliant design to engineering and permits, and then certified DNL technicians will handle the installation.


Combine ever-changing building and fire codes with the limited life span of fire alarm systems, and inevitably you’ll need an upgrade. To make sure you’ve got the safest code-compliant system, you may want to consider an upgrade if you experience any of the following conditions:

  1. Complete Failure
  2. Excessive Maintenance
  3. Parts Difficult to Source
  4. New or Upgraded Elevator Installation
  5. System No Longer Meets Code
  6. Space Renovations

Along with our responsiveness, diligence and professionalism, another thing that sets us apart from everyone else is the fact that we’ve upgraded or replaced thousands of systems that were either obsolete or malfunctioning. So, if you’re looking for a team of technicians that can handle every aspect of an upgrade from design to installation, look no further than DNL .
