The GEZE FTV 320 emergency exit door opener - a new design principle Greater resistances, simpler to handle

GEZE at BAU 2011 from 17 to 22 January 2011 in Munich - Hall B1, stand 538
The new GEZE FTV 320 emergency exit door opener (PresseBox) (Leonberg, ) Whether in supermarkets, chemists' or industrial buildings - doors frequently have to fulfill dual functions. If in their function as a side-entrance they also have to double as a delivery door and an escape route at the same time, then their safety functions are in a particularly critical field. Emergency escapes and rescue routes must always be open in case of danger and may not be locked, since - when it comes to the wire, it must be possible to evacuate a building through the escape door as fast as possible. When there is no emergency, locks are there to protect against unauthorized access and make possible the controlled opening of a door. After it is opened, as protection against misuse it must lock itself again automatically - that's what the insurance companies demand.

System solutions in emergency exit routes

Escape route control and controlled access by a door - it is now a matter of bringing these two requirements into line in a co-ordinated fashion. For this purpose, GEZE offers integrated safety systems which fulfill all the strict legal demands and guidelines. They will be defining the future and indeed they should already be a matter of course today. The use to which a building is put or its rescue route concept will normally decide the choice of electric system components. These include door closers, automatic door drives with self-locking panic locks, fire and hazard alarm equipment, access control systems, escape door openers and central door controls. The last mentioned act as the "brains" of the rescue route system.

An intelligent system solution e.g. for swing doors, is the combination of a door control unit, an emergency exit door opener and a panic lock. From a technical insurance point of view, this means that the door is locked by the self-locking action of the lock in normal operation and is controllable and secured by the central door unit. In daily operation, the door can be released at certain specified times by the door control unit. At other times of day, the door control unit can enable controlled individual releases such as by an access control system or a key switch. In an emergency, the door will be negotiable at any time through release by the fire alarm system or activating the emergency switch from the door control unit. Then the emergency exit door opener releases the latch of the lock and the door is unlocked.

The FTV 320 principle: the three-latch design for maximum holding power

GEZE has totally reworked the principle of the emergency exit door opener. The result is the new development the FTV 320. In conjunction with the panic lock, this will open doors even when there is a power failure and great resistance such as when people are pressing against them in panic situations. The special new door opener construction with three latches results in a holding power in excess of 4,000N. In an emergency, the FTV 320 will then open doors cleanly and without the latches jamming even when several people are pushing against it. Thus the emergency exit door opener guarantees not merely maximum safety for people escaping from inside the building but also enhanced security against break-in and protection for the shell of the building from the outside.

Extended possibilities for application

The small FTV 320 lock housing fits in all door frame constructions. A compact building element with the two components emergency exit door opener and locking plate can be used for all the escape doors in a building and simplifies planning. The locking plate instead of the more usual latch lock reduces the amount of chiselling in the door, thus saving on both time and the costs of installation. The new design and functional principle also extends the range of application: because the latches are drawn back into the lock itself, installation of the FTV 320 is possible both in a door frame and in a door leaf. Thanks to the small current consumption, up to three door openers can be wired up to a door control unit - a welcome advantage which improves the holding power particularly of double-leaf doors, distributing it optimally over the frame.
