Maintenance of fire safety systems (FSS)

A fire safety system (FSS) is useless if it is not fully functional at all times. If you don't maintain your equipment regularly, you're taking a major risk to the safety of people and property.

Compulsory and necessary maintenance
to ensure the long-term future of your facilities
and ensure their optimum efficiency

Legal obligations

The maintenance of a fire safety system (FSS) consists of testing and maintaining all the components of a fire safety installation from its commissioning to its upgrade: fire control panel, smoke detectors, automatic extinguishing, safety sound system, mechanical smoke extraction, emergency exit management, etc.

Mandatory, it is governed by the NFS 61-933 standard and more specifically by Article 7.

A range of maintenance services

Preventive

Preventive maintenance

This is the only maintenance regulated by standard NFS 61-933. It is compulsory up to twice a year. This involves not only maintaining the equipment, but above all testing all the components of the fire safety system. The technician must be APSAD-certified and follow a precise and comprehensive mission protocol.

Palliative

Palliative maintenance

Also known as on-call or telephone maintenance, this involves intervening within a predetermined period when a fault or failure is reported. For example, if a public building is open 24 hours a day, the technician must be able to intervene 24 hours a day.

Corrective and curative

Corrective and remedial maintenance

The technician intervenes on site to repair a fault (curative maintenance). If he it is unable to repair the damage immediately, he implements compensatory measures to protect the building while awaiting repairs (corrective maintenance).

Provisional and conditional

Predictive and conditional maintenance

Predictive maintenance involves identifying in advance the equipment to be replaced. For example, smoke detector batteries must be changed every four years. Conditional maintenance consists of identifying faulty equipment that needs to be replaced in the near future. For example, a clogged smoke detector would be less effective.

Upgrade

Upgrade maintenance

As the name implies, upgrade maintenance involves making the system perform better or better adapted to a given situation.

What's the difference between a service contract
and a maintenance contract? 

The maintenance contract consists of a visual check that the equipment is working properly. This check does not comply with the requirements of standard NFS 61-933, as it does not include testing of all the equipment.

The maintenance contract includes all the services described above. It is supported by detailed maintenance schedules to help you control your budget.
