For annual inspection/maintenance, the system is taken out of the switch cabinet in
order to perform bigger maintenance tasks. It is necessary to consult the owner in
this instance.
In order to avoid failures at a superordinate position during servicing tasks, revision
can be actuated.
INFORMATION
Many sensitive, networked components/servers are mounted in switch cabinets.
Significant loss can be incurred by the owner in the event of damage or careless
actions. Act with care so that no existing plug connections are removed or dam-
aged.
It is preferable for maintenance to take place on a fixed workspace which was
designed for this purpose and has a 100 V to 240 V connection.
Annual Inspection/Maintenance (Authorized Distributor)
Visual inspection, full maintenance (e.g. check and clean the suction pipe and dis-
charge nozzle where applicable, check the cover seal, replace the filter for the air
flow sensor where applicable, check and set air flow calibration where applicable)
and function test.
The event memory must be checked for failures
In the course of maintenance, the system is checked fully and, where applicable, put
back into target state. Non-compliance with these intervals can cause failures and
false alarms and consequently to faulty extinguishing.
During maintenance, the total weight of the system must be reported.
Maintenance every two years (Authorized Distributor)
The Authorized Distributor must perform maintenance work to the system at least
every two years. This maintenance prompt is shown in the display.
After not later than two years, as part of the two-yearly maintenance, the batteries
for the emergency power supply must be changed.
A total service life of 10 years is set for the integrated detectors employed in the
system if used in dry areas free from combustible dust and corrosive atmosphere.
Regular inspections, maintenance, cleaning and calibration where applicable are
prerequisites for this.
In isolated cases, shorter periods for changes may be required depending on
ambient conditions or fire detector type.
The maintenance tasks are documented in the checklists that are intended to serve
this purpose.
