Deadlines & standards
When automatic fire detectors to DIN 14675 and in fire warning systems to DIN VDE V 0826-2 must be replaced.
Legal situation & liability: detector replacement is mandatory
If your fire alarm or fire warning system is required under building law – for example in the building permit or in the fire protection concept – it must be operated in accordance with DIN 14675 and DIN VDE 0833 or DIN VDE V 0826-2 as applicable. Overdue detectors can go as far as leading to a prohibition on the use of the building. Owners, operators and responsible personnel are liable in the event of damage.
For operators

You are responsible for the proper operation of your fire alarm system. We supply the new detectors and, if required, replace them at the same time – on schedule and with documented proof.
