Fire protection Munich

A locking system is a technical device that keeps self-closing fire or smoke protection doors securely in the open state (locks). In the event of a fire, this locking is automatically lifted by fire detectors (e.g. smoke detectors), so that the door closer can close the door securely. This prevents the spread of fire and smoke into other parts of the building. An FSA typically consists of a power supply, a trigger device, fire detectors and a locking device (e.g. a holding magnet).

Regular maintenance is of the utmost importance for several reasons:

Life-saving function: Only a perfectly functioning system ensures that the protective doors close reliably in an emergency and thus keep escape and rescue routes smoke-free.

Legal obligation: The operator of a building is legally obliged to ensure the operational readiness of the parking system at all times. The requirements are clearly defined in the DIN 14677 standard and in the general building supervision approval (abZ) of the German Institute for Building Technology (DIBt).

Insurance cover: In the event of damage, an insurance company may reduce or refuse to provide service if there is no proof of proper maintenance of the system.

Avoidance of manipulation: A functioning FSA prevents fire doors from being wedged or blocked inadmissibly - an action that is life-threatening and even punishable.

The test periods are precisely defined in DIN 14677 and comprise two different intervals:

At least once a month: A functional check by an instructed person of the operator.

At least once a year: A complete inspection and maintenance by a specialist for parking systems (a qualified specialist company).

All inspections and maintenance work must be completely documented in a test book.

The responsibilities are clearly separated:

Monthly function check: This may be carried out by an instructed person. This is usually an employee of the operator (e.g. The caretaker), who has been demonstrably instructed by the installer of the system or another specialist in the operation and inspection of the specific system.

Annual maintenance: This must be carried out by a "specialist for parking systems". These are certified experts from specialist companies who have a certificate of competence according to DIN 14677 and are familiar with the electrotechnical and mechanical components as well as the applicable regulations

During the annual maintenance by the specialist, all components of the system are systematically checked. These include, among others:

Check triggering: Test triggering of the system via each connected fire detector (e.g. with test aerosol).

Manual release: Control of the manual release controller.

Door and closer: Check that the door closes cleanly and without obstacles after the release and that the door closer is adjusted correctly.

Power supply: Measurement and testing of the emergency power supply (batteries).

Components: Visual inspection of all components for damage, firm fit and contamination.

Documentation: Detailed logging of all test steps and results in the test book.

The neglect of the prescribed tests can have serious consequences:

Safety risk: In the event of a fire, the system fails, which can result in the spread of deadly smoke.

Legal consequences: The operator acts in violation of the regulations and is liable in the event of damage civilly and possibly also criminally.

Loss of insurance coverage: The building insurance may refuse to regulate fire damage.

Complaint by authorities: In the case of fire protection inspections by the building inspectorate or fire brigade, a poorly maintained system leads to complaints and orders to eliminate defects.
