AES TUEV

• In the case of single-fan operation, it must be ensured that the other fan is
automatically switched on as well.
• The failure of a fan must be visually indicated on the control cabinet and visually or
acoustically indicated or signalled in the car park or at a constantly manned point.
• The possibility to activate the ventilation system via a CO system or a fire alarm
system (smoke extraction) must be provided.
• In the ‘smoke extraction’ operating mode the motor protection devices must be
disabled in accordance with the principles for the testing of technical systems and
installations according to the Type Testing Regulations by experts recognised by the
building authorities (Building Authority Expert Commission of the Conference of
Ministers of Construction, Edition of December 2001, Part B, point 3.2).
• If the ventilation system consists of a supply and exhaust air system, both systems
must be linked together in the same control system. It must be ensured that no
overpressure is built up in the underground car park in the event of a system
malfunction.
• The controller must be independent of the controllers and bus systems of the Building
Management System.
When linking, the mutual non-reactivity from and to higher-level systems of the
management system must be ensured.
6 Summary
The components AES-ST3 and L-TG3-JET-Z-CONTROL described in the submitted
documents are suitable for the construction of fan controllers for underground car parks
that conform to the requirements contained in Section 14 of the Bavarian Car Park
Ordinance of 30 November 1993 and in DIN VDE 0100-718.
The above-mentioned requirements for the technical equipment and functions applicable
to the respective project are to be implemented by means of appropriate system
planning and realised in the construction of the system.
