Fire Alarm System Test and Inspection Services

All of the services ASSI performs are in accordance with the latest NFPA standards.


Fire Alarms: NFPA 72


  • We will inspect and service most brands of fire alarms with highly skilled, licensed, and trained technicians.
  • We will work with your existing system or assist in designing and installing a new one for you.
  • Properly inspected and maintained fire alarms and security systems simply work better. Our reasonably priced inspection and service rates set us apart from our competition.

 Annual Inspection:

  • Inspect the system per NFPA standards to determine whether it is in service and in satisfactory condition.
  • Identify potentially detrimental site conditions that could compromise the performance of mechanical and/or electronic components of the system.
  • Inspect the condition and test the operation of the main fire alarm panel.
  • Inspect and test smoke and heat detectors.
  • Inspect and test all enunciators and zones.
  • Inspect and meter all batteries.  With prior authorization we can replace outdated batteries while on site rather than returning for a follow up.
  • Inspect all output relays and test their activation.
  • Inspect and exercise all flow switches, tamper switches, and low-pressure alarms.
  • Verify that all signals are received by the central station or monitoring company, if applicable.
  • Clean the detectors as needed in accordance with the manufacturers guidelines.
  • Perform functional test on all accessible heat-actuating devices.
  • Inspect and exercise all supervised control valves and switches.
  • Tag devices as required and perform all required record keeping.
  • Compile a complete report of the inspection.
