For milock VARIfree installation, only specifically authorised panic locks can be used. Anti-panic locks that are accredited for the implementation of knob cylinders/free-movement cylinders must be used. These panic locks are approved for locking mechanisms which allow an undefined positioning of the cylinder lock lug. Standard anti-panic locks cannot be applied with milock VARIfree. These standard locks are identifiable by the warning information on the packaging. Anti-panic locks with this warning information may not be implemented with milock VARIfree. If you are retro-fi tting with existing anti-panic locks, tests must be carried to establish whether the lock has the corresponding authorisation. If this is not the case, the mortise lock must be changed.
 

The main purpose of the DIN EN 179 draft standard “Emergency exit devices operated by a lever handle or push pad, for use on escape routes – Requirements and test methods” is the testing of products with regard to their fitness for the purpose of allowing a safe escape through an emergency exit door with only one activation of the emergency exit lock.

DIN EN 1906 specifies requirements and testing procedures for door handles and door knobs. Qualities such as long-term usage, resistance to corrosion, free movement and transfer are tested.

Whisper locks have a specially laminated bolt through which the closing of the door is particularly quiet. The implementation of whisper locks is particularly recommended in hotels.

MIFARE is worldwide technology for touch-free chip cards based on the ISO 7816 and 14443A norms. Originally developed by Phillips, MIFARE has established itself as the de-facto international standard.

Radio Frequency Identification (RFID) is a technology designed for the identification and localisation of objects with the help of electromagnetic waves. An RFID system is composed of a transponder which is in the possession of the object (i.e. a card) and a reader unit for the processing and interpretation of the recognition (e.g. electronic fittings, electronic cylinder, wall reader etc.).

Recommended for VARIfree Special. The small additional latches under the actual latch tell the mortise lock that the “door is closed”, which automatically activates the bolt. So when the door meets the lock, it is not only closed but also locked. Even if the door is locked, it can still be opened from the inside just by turning the door handle.
 

Access authorisations for offline components which are only valid for one day at a time are called day tickets. The authorisations are saved on the cards of those authorised and are usually extended automatically at a read/write unit. If the card is blocked on the online system, the authorisations cannot be extended and therefore no longer be used. The manual blocking from the affected offline components is not required. The implementation of the day ticket is therefore an efficient method for integrating the online and offline systems.

Practical example:

Employee Smith has permissions to the offline equipment group “Corridor 2” on his Mifare card for the online system. He prolongs these permissions every morning with each daily clock-in at a reader/writer in the reception area.

Since Smith has to stand in for employee Johnson while he is on holiday, he also needs offline permissions to “Corridor 1” for the period of one week. He can have these permissions written onto his card either via the programming station in the secretary’s office or comfortably via the online slave terminal. He then prolongs these permissions each day anew over the period of a week.

Because employee Jones is sick, Smith now also needs short-term permissions to the server room, in order to check on a functional disturbance in the air conditioning system. Permission to access the stand-alone device for one day is written onto his card.

Should employee Smith ever lose his card after work, it will simply be blocked in the online system. That way, the permissions to the offline system cannot be prolonged on the next day. There is no need to go to the offline systems in question to manually block them.

The possibility of opening an electronic door lock for a longer period of time by way of holding the access card over the electronic lock for a longer period of time, before it is closed again in the same way, is called the toggle function. This optional function must be activated explicitly and is designed particularly for seminar rooms which need to be freely accessible for particular situations.

A transponder is an electronic component that can receive and answer radio signals. Generally, so-called passive transponders with only a short range are used which do not require their own power supply and therefore allow lesser components, such as cards and coins, to be used.
