1) General Safety Instructions

Since the RZ-24 central is used in both non-EX hold-open systems

and EX hold-open systems, this manual contains important

information on both areas of application. Information relevant

only for the EX area is marked with

The RZ-24 central is a power supply with integrated tripping device for

hold-open systems on fire doors, smoke evacuation flaps etc.

The RZ-24 is also the central of the DICTATOR hold-open system in

hazardous areas. The central itself is not protected against explosion and

therefore has to be mounted outside the hazardous area.

When installing the ex-proof hold-open system, it is imperative to observe

the instructions for implementing the 2014/34/EU directive and the safety

instructions. Furthermore the regulations, especially regarding the marking,

execution, approval, operation and maintenance, corresponding to the

type approval Z-6.500-2443 of 17 October 19 have to be met.

Only trained professionals may effect the installation; e.g. only a qualified

electrical technician may connect the power supply to the mains. To the

electrical installation following the power supply ( safety extra-low voltage

24 VDC) apply the acknowledged technical regulations for electrical

installations. In the hazardous area all the demands applying to this area

have to be adhered to (type of cables, marking of cables for intrinsical

electric circuits, equipotential bonding etc.).

Only a professional trained by DICTATOR with an approval authorisation

may approve the system.

The relevant regulations must be observed for all work.

The operation of all components is only permitted in undamaged

The accident prevention regulations have to be respected.

The operating company has to determine and document the hazardous

zones according to the explosion protection document where the ex-proof

hold-open system shall be installed.

During installation the respective ignition protection type of every individual

component has to be respected.

The RZ-24 central and the Zener barrier may solely be

installed outside the hazardous area. Only exception is

when they are supplied in a pressure capsulated, ex-proof

housing.
