Common Fire Protection & Backflow Questions

Fast answers for owners, property managers and contractors planning fire inspections, backflow certification, repairs and documentation.

What should I send before scheduling service?

Send the property address, service notice or due date, system type if known, access notes, and any photos or reports you already have.

Does AO handle both fire protection and backflow work?

Yes. Fire protection is the primary focus, and AO also supports annual backflow certification, backflow repair, installation support and water compliance documentation when the property needs it.

What areas does AO serve?

AO serves commercial properties across the Colorado Front Range, including the Denver metro area, Colorado Springs, Northern Colorado and nearby communities.

What is included in a fire sprinkler inspection?

A sprinkler inspection can include visual review, testing of system components, gauges, valves, waterflow or supervisory checks, deficiency notes and written inspection documentation.

How often should fire sprinkler systems be inspected?

Many commercial sprinkler systems need annual inspection and may also require quarterly or other periodic checks depending on the system, building, local authority and inspection standard.

What is a five-year internal fire sprinkler inspection?

Commonly called a five-year internal inspection, this service examines selected points inside sprinkler piping, valves and related components for corrosion, scale, foreign material or other conditions that could restrict water flow. AO confirms the required scope from the system type, prior records and locally adopted inspection requirements.

What happens during a three-year sprinkler inspection?

For applicable dry-pipe and preaction systems, three-year service can include a trip test that verifies valve operation and confirms water reaches the system test point. The exact test method depends on the system design, prior results and locally adopted requirements, so AO confirms what is due before testing.

Does AO send inspection-due notices?

Yes. AO sends advance reminders for recurring sprinkler inspections to the property contact on file, helping owners and managers plan access and schedule service before the due date. Keep AO updated when contacts or management companies change so the notice reaches the right person.

What happens if the inspection finds a deficiency?

The deficiency should be documented clearly, reviewed with the property contact and corrected or coordinated with the right qualified provider before follow-up records are completed.

Can AO service fire extinguishers?

AO supports extinguisher service planning, annual tag needs, visual inspection, maintenance coordination and replacement guidance for commercial properties.

Do emergency lights and exit signs need inspection?

Yes. Emergency lighting and exit signs should be checked so occupants can find a safe exit path during outages or emergencies, and so the property has current life-safety records.

Can AO help when sprinkler work touches alarms or hood systems?

Yes. AO can document the sprinkler-related work and coordinate the appropriate next step when alarm, monitoring, suppression or kitchen hood systems are involved.

How do I know if backflow certification is due?

Check the water district notice, last test report, utility portal, property compliance calendar or renewal reminder. AO can review the notice and help identify the required next step.

What backflow assemblies can AO test?

AO can help with annual testing and certification for common commercial domestic, irrigation and fire line backflow assemblies when they are accessible and ready for testing.

What if a backflow assembly fails?

A failed assembly usually needs repair or replacement followed by retesting and updated certification paperwork. AO can explain the test results and recommend the appropriate repair or replacement path.

Can AO submit reports to the city or water provider?

AO can provide required inspection and backflow testing documentation and submit reports directly where the local program supports or requires that process.

Can property managers schedule multiple buildings at once?

Yes. Send the property list, due dates, site contacts and known system needs so AO can group work logically and keep records organized by address.

Who should I contact for urgent fire or water service?

Call AO directly for urgent fire protection, water or compliance issues. If there is an active fire, life-safety emergency or immediate danger, call emergency services first.
