FireFlex Maintenance Basics: What Should Owners Do After Installation?

In plain terms, maintenance means confirming the system remains in its intended operating condition over time.

Owner’s responsibility

Once the system is turned over, the owner or operator is responsible for maintaining it. That usually includes:

• Keeping valves in the correct position
• Preventing physical damage or obstruction
• Scheduling inspections and tests
• Maintaining records
• Correcting deficiencies promptly

Even a well-designed system can become unreliable if it is neglected after handover.

Regular inspections

The exact schedule depends on system type and local requirements, but regular checks often include:

• Control valve position
• Pressure indication
• Condition of gauges and trim
• Supervisory and alarm status
• Physical damage or corrosion
• Access clearance around the assembly
• Room environmental conditions

For systems in mechanical rooms or industrial spaces, it is also important to look for vibration, leaks, contamination, or unauthorized changes.

Importance of records

Inspection and testing records are part of the fire protection program. Good records help answer important questions:

• When was the last inspection completed?
• Were any deficiencies found?
• Was corrective work completed?
• Have operating conditions changed?

Without records, it is hard to prove system readiness or identify recurring issues.

Environmental changes

A system that was correct on day one may need review later if the space changes. Examples include:

• A heated area becomes seasonally unheated
• A clean equipment room gains new ventilation openings
• Storage changes create a higher hazard classification
• Corrosive conditions increase
• Access to the assembly becomes blocked

Owners should treat building changes as fire protection review triggers.

Special attention for certain systems

Some systems need more focused monitoring because of their operating method. For example:

• Dry and preaction systems may require attention to air or nitrogen integrity
• Corrosion mitigation arrangements need verification that they are functioning as intended
• Clean agent systems require enclosure integrity and cylinder status review
• Detection-based systems require both releasing and sprinkler-side inspection

More complexity means more need for disciplined maintenance.

When to call qualified service personnel

Owners should involve qualified fire protection service professionals whenever they observe:

• Low or abnormal pressure
• Damage to trim or controls
• Trouble or supervisory signals that do not clear
• Signs of corrosion or leakage
• Building use changes that may affect system suitability
• Questions about testing or restoration procedures

Do not improvise on a life safety system.

A practical example

A dry system protecting a loading area may appear normal for months, but if pressure losses are ignored, trip performance can be affected and maintenance needs may go unnoticed. Routine checks catch those issues before they become larger problems.

Benefits of maintenance

Regular care does more than support safety. It can also help reduce:

• Unplanned service calls
• Startup problems after outages
• Costly repairs
• Downtime during inspections
• Support requests caused by preventable issues

Next steps

Create a maintenance schedule, assign responsibility, keep records in one place, and review any change in occupancy or environment against the original system design.

Frequently Asked Questions

Can building staff perform all maintenance themselves?
Routine visual checks may be handled internally, but code-required testing and service should be completed by qualified personnel as required.

How often should the system be inspected?
That depends on the system type, code requirements, and local authority expectations.

What if the building use changes?
The fire protection design should be reviewed.

Do specialty systems require different maintenance?
Yes. Always follow the applicable instructions and standards for that system type.
