2. General Regulations for Hold-Open System

In Germany, the installation of a hold-open system is regulated by the

general building inspection 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 available to our

authorised specialists for DICTATOR hold-open systems.

In the Ex-area a hand switch with appropriate explosion protection must

be used.

Only cables approved for this purpose may be used in the Ex-area (e.g.

Ölflex EB 2 x 0.75 mm²). The cross-section must be selected according

to the required cable length.

Depending on the application (must be clarified object-related), we re-

commend shielding the cables.

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.

To ensure the correct functioning of the hold-open system, the DICTA-

TOR smoke and heat detectors 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.
