2. General regulations for hold-open system
2.1 DEMANDS
In Germany, the installation of a hold-open system is regulated by the general building inspec-
tion approval or type approval of the DIBt. For European countries without national regulations,
EN 14637 is used as a guideline.
These regulations also govern:
the mounting positions and number of fire detectors
the position and design of the hand switch
the acceptance test (first placing in service) and marking
the recurring functional tests and maintenance
the requirements for the qualification of the persons testing and maintaining
The documents are available under www.dictator.de. The general type approval DIBt also
includes all permissible device combinations.
For further instructions on installation, use, maintenance, functional testing and servicing as well
as documentation, please refer to our operating manual for hold-open systems, which is avail-
able to our authorized specialists for DICTATOR hold-open systems.
IMPORTANT
The device combinations "RZ-24" and "RZ-24-05" have to be
mounted in the detection range of one of the fire detectors of the
respective door. If not, an additional detector is required.
2.2 OPERATIONAL LIFE
To ensure the correct functioning of the hold-open system, the DICTATOR smoke and heat detec-
tors have to be replaced after a maximum of 8 years of operational life. In Germany the DIN
14677 regulates the replacement obligation of fire detectors in hold-open systems.
