Explanations on fittings
In the following we have summarized the most important information on terms that require explanation.
For doors that are only intended to be accessible to a certain group of people from the outside and may therefore only be opened with a key. The outside of the door is equipped with a knob or push handle and the inside (panic side) with a lever handle, panic bar or panic push bar.
- The door must be permanently open in the escape direction (lever handle, panic bar or panic push bar are always coupled).
- From the outside, the door can only be opened with a key or via the E-opener function (changeover function).
For emergency exit doors, where passage from the outside to the inside must be possible at times. The outside is equipped with a lever handle, the inside (panic side) with a lever handle, panic bar or panic push bar.
- In escape direction, the door must be permanently open (lever handle, panic bar or panic push bar always coupled)- Latch and deadbolt are retracted when operated.
- For temporary access, the outside lever handle can be coupled via the profile cylinder - locking the door restores the panic and idle functions (switchover function).
- Even if the lever handle on the inside is operated, the outside lever handle remains uncoupled.
For emergency exit doors where passage from inside and outside must be possible at times. The outside is equipped with a lever handle and the inside (panic side) with a lever handle, panic bar or panic push bar.
- These doors are escape doors, which are only used in case of panic.
- The door must be opened permanently in the escape direction (lever handle, panic bar or panic push bar are always coupled).
- By actuating the inner lever handle, the outer lever handle is coupled - thus allowing rescue services access from outside (passage function).
- The outside of the door can only be locked again with the key.
For emergency exit doors where passage from inside and outside must be possible at times. The outside of the door is equipped with a lever handle and the inside (panic side) with a lever handle, panic bar or panic push bar. Access control systems or devices (card readers/finger scanners/timers) can be used to control the lock and to connect or disconnect the lever handle.
- In escape direction, the door must be opened permanently (lever handle, panic bar or panic push bar are always coupled) - latch and deadbolt are retracted when operated.
- For temporary access, the outside lever handle can be coupled or uncoupled via the mechatronic components in the lock or via the profile cylinder. When the door is locked, the panic and idle functions are restored.
- The lock enables the following queries:
- Lever follower inside and outside
- Status of the bolt
- Actuation of profile cylinder
The CE mark on construction products confirms their suitability for use and represents a minimum safety standard for the European internal market. This prevents each state from issuing individual regulations for technical products. CE-marked products meet the minimum requirements of the European Construction Products Regulation (CPR).
The CE mark is not a seal of quality, rather it is to be understood as a "passport".
Locks for emergency exits with fixed knob and lever handle along with lever handles on both sides are used for emergency exit doors in buildings where the occurrence of panic is unlikely.
Possible areas of application:
- Office space
- Non-public areas at railway stations, airports, etc
Emergency exit locks for fire and smoke protection doors and for escape route doors in accordance with DIN EN 179 must bear the CE mark.
According to DIN EN 179, only handles that do not have any protruding corners and edges that could lead to injuries may be used. The free end of the lever handle must face the surface of the door.
It must be possible to open the door within one second with manual operation and a maximum necessary force of 70 N.
Panic locks with horizontal operating bar, across the entire width of the door for emergency exit doors, are used in buildings where panic is possible. People are not familiar with escape routes and the functions of emergency exit doors.
Panic locks for fire and smoke protection doors and doors in escape routes in accordance with DIN EN 1125 must bear the CE mark.
It must be possible to open the door within one second with manual operation and a maximum necessary force of 80 N (door without preload) or 220 N (door preloaded with 1,000 N).
The European standard EN 1154 defines the requirements and test methods for door closers. The requirements are classified in a six-digit designation system.
DIN 1527 specifies requirements for the manual construction system for sliding doors as well as double and multileaf folding doors. Doors and door leaves themselves are excluded.
Cyclic tests, static loads, initial friction and corrosion resistance tests are carried out for fittings and guide rails. Drives for industrial, residential sliding and folding doors are treated. The standard does not apply to sliding doors with corner guide and light bottom-running sliding doors.
Burglar-resistant components according to DIN EN 1627-1630 are defined in different resistance classes. The standard defines a total of 6 resistance classes/resistance class (RC).
Components of class RC2 have low protection against attempted break-ins using lever tools. The resistance time of the components is 3 minutes. The highest resistance class RC6 withstands the burglary attempts of experienced perpetrators for 20 minutes. This assumes the additional use of very powerful power tools such as drills or angle grinders.
DIN EN 1670 specifies the requirements for the corrosion resistance of fittings for windows.
There are five classes of corrosion resistance (classes 1 to 5) according to the different conditions of use. These apply to both coated and uncoated surfaces.
DIN EN 12101-2 describes the European requirements for natural smoke and heat exhaust ventilators (NSHEV).
The standard states that only tested complete solutions (NSHEV), consisting of window and drive as well as rim, NSHEV fitting, skylight dome and wind deflector guide may be used, which have a proof of usability prescribed in § 17 of the Model Building Code (MBC). This can be either a CE mark for legally regulated building products in the case of standard devices or an approval in individual cases (ZiE) for individually designed facades and roof designs.
DIN EN 12209 specifies requirements and test procedures for the long-term functional efficiency, strength, protective effect and mode of action of mechanically operated locks and their striking plates. Locks according to DIN EN 12209 are typically used on doors, French windows and entrance doors.
DIN 18251 specifies the dimensions of the locks. It replaces the old standards DIN 18251-1/-2/-3 and 18250. The required specifications for locks, such as permanent function, strength, etc., are now only defined in DIN EN 12209.
DIN 18263-1 "Door closing devices with controlled closing sequence" describes the requirements and test methods for swing door drives with self-closing function. In many cases, these automatic, i.e. power-operated swing doors must also meet fire protection requirements.
DIN 18273 certifies door handle sets for fire and smoke protection doors, which are designed in such a way that, when used properly and with appropriate maintenance, the function and protective effect of the fitting is permanently ensured even after prolonged use. The standard applies to all types of door handles in single or double-leaf design.
DIN EN 1935 is the European standard for single-axis door and window hinges. Depending on the application, the hinges are divided into four different use classes (light, medium, strong, very strong). The door weights and dimensions as well as the maximum torque resulting from the frictional resistance during the continuous operation test are essential for evaluation.
According to the standard, all single-axis screw-on hinges and hinges with fixed pins for use on entrance doors and windows must be assessed according to an 8-digit classification key.
- Service class (classes 1 - 4)
- Long-term functionality (classes 3, 4, 7)
- Door mass (Classes 0-7)
- Fire resistance (classes 0-1)
- Safety (Class 1)
- Corrosion resistance (class 0-4)
- Protection and burglary resistance (class 0, 1)
- Band class (classes 0-14)
Fittings tested according to the QM 328 certification programme of ift Rosenheim meet the RAL requirements for turn and turn/tilt fittings. The certification according to QM 328 creates an interchangeability of the fittings, based on a technical comparability in building elements according to DIN EN 14351-1.
The QM 328 is issued for a period of 5 years. Subsequently, it is re-certified for a further 5 years.
As a manufacturer of high-quality window fittings, we are committed to factory production control to ensure the consistent properties of our fittings. This includes incoming goods inspection, production monitoring and a check of the marking.
The RAL quality seal is awarded by the "German Institute for Quality Assurance and Labelling".
The RAL Seal of Quality is awarded to companies that meet the strict quality and testing requirements for their product or service. After an initial inspection, compliance with the regulations is ensured by regular in-house and neutral external monitoring.
The whisper latch considerably reduces the closing noise of a door. The remaining noise sounds "richer" and thus gives doors a higher quality impression.
Thanks to a special plastic insert on the latch, regular lubrication is no longer necessary and thus also possible dirt deposits caused by lubricants.
Thanks to intelligent locking technology, anyone who wants to open doors and gates today does not necessarily need a key - a fingerprint is all that is needed. The front door unlocks by itself when the finger is placed on it by an electric motor.
Moreover, the fingerprint is unique and cannot be copied. It cannot be lost or forgotten.
Flat stainless steel core pulling protection rosettes protect the profile cylinder from manipulation and prevent the cylinder core from being pulled.
Locks with electronic handle control protect people, rooms or sensitive data from unauthorised access. The time or person-related restrictions of access rights are operated via time switches, finger scanners or card readers.
Switching locks, e.g. 14.288. of the 200 series system locks, are used in double-leaf systems. They are installed in the upper area of the inactive leaf. When the locking rods of the panic counter-box or rebate drive deadbolt are fully retracted, the single-stage latching of the switching locks prevents the spring-loaded locking rods from extending. Possible damage to the floor and unsecured closing of the inactive leaf are excluded.
Dead man's controls can be found on gates with drives. They ensure that the drive for opening or closing only works as long as the button is pressed. If the button is released, the operator stops.
