Hold-Open Systems Summary, Regulations Depending on their use and size, buildings are divided into fire areas to prevent a possible fire from spreading in the whole building. As a matter of principle openings in the walls between the fire areas are not allowed. For this reason doors which connect the fire areas have to be approved fire protection closures which always close on their own, i.e. after every opening they close automatically. However, the normal course of operations often requires that doors stay open in order not to interfere with or even endanger the movement of people and material...

Hold-Open Systems Summary, Regulations Hold-Open Systems - Structure and Functioning Fire doors are still often kept open by wooden wedges to make passing easier - although this is forbidden. In the case of a fire this wedging or blocking prevents the closing of the door. The safety of the object is no longer ensured, because nothing would hinder a fire from spreading. Installing a hold-open system which meets the demands is the only legal action to keep fire protection closures as long open as the normal use requires it and at the same time to ensure their reliable closing in the event of a...

Hold-Open Systems Summary, Regulations Hold-Open Systems - Structure and Functioning, cont. As a matter of principle you can install a hold-open system on all fire protection closures according to the specification of the door manufacturer. They should always be installed when open fire protection doors essentially simplify the movements in the building. Due to the great importance of the faultless functioning of a hold-open system, only qualified persons may approve/accept, test and maintain it. A qualified person has to confirm the correct first placing into operation on a defined plate in...

Installation Regulations In Germany the installation directives for fire detectors are to be found in the respective approval of the building authorities or the general type approval. In other countries apply the corresponding directives for hold-open systems. In case there exist no directives, in Europe the EN 14637 serves for orientation. In the following you will find the prescriptions about the number and the mounting position of fire detectors in Germany. The following diagrams will help you to choose the correct number of detectors. When in the following "ceiling detectors" are required,...

Hold-Open Systems Summary, Regulations Electrical Installation, Other Prescriptions The installation of the hold-open system on site should be carried out by professionals who are familiar with all the necessary tasks, the corresponding local and national prescriptions and have the necessary certificates. They have to obey the installation instructions of the manufacturer of the components of the hold-open system. The technician as well as his company are responsible for the correct installation of the hold-open system. The same applies to handing over the acceptance documentation of the installation...

RZ-24 Central Unit for — Hold-Open Systems The RZ-24 central unit is the core of the DICTATOR hold-open system. This one device combines all essential functions, so that in the simplest case you only have to connect fire detectors and electromagnets. - It changes the 230 VAC mains supply in 24 VDC for feeding the connected fire detectors and electromagnets. - It evaluates the signals of the fire detectors. - I n the event of an alarm or a failure it interrupts the power supply of the electromagnets and thus automatically initiates the closing of the fire/smoke door. - In case of an alarm or a...

RZ-24 Central Unit for Hold-Open Systems RZ-24 Central Unit with Power Pack and Tripping Device The RZ-24 has been tested and approved by the Deutsches Institut für Bautechnik (German Institute for Building Engineering). It also meets the demands of the EN 14637. Due to its high performance (900 mA) even large hold-open systems can easily be operated by one central unit. As an option the RZ-24 central unit is available in a bigger casing (part no. 040554) (dimensions 202 x 152 x 90 mm). This offers enough room for additional components as e.g. relay circuit boards or an emergency power supply...

RZ-24 Central Unit for Hold-Open Systems RZ-24 Central Unit - cont. The door approvals, standards and prescriptions of the accident prevention regulations/ safety at work may stipulate the optical and acoustical signalling of the closing. This is easily possible with the RZ-24. DICTATOR provides a signaller (part no. 700171) for this purpose which features besides the red LED warning flashlight also a siren which can be switched off - and an extremely low power consumption. In some countries as e.g. Austria it is prescribed that in underground car parks the warning signal has to start before...
