Lock cylinder with emergency key function (GF)

User requirements for a building or apartment can vary considerably. In industrial buildings, hotels, hospitals, commercial buildings, blocks of flats or a private residence, the building conditions and door situations vary from site to site.

In everyday life, we usually need to weigh up security and convenience when it comes to access to the building or individual building areas. Mechanical, mechatronic and electronic solutions and keys are often used in such cases.

However, security in an emergency should not be disregarded. In an emergency, it must be possible to leave a building safely and the emergency services must be able to reach hazardous areas quickly in order to save lives.
For this reason, the relevant doors should be equipped with lock cylinders which also release in an emergency.

Our lock cylinders are fire-protection tested according to EN 1634-1 or EN 1634-2 and comply with high security requirements.
Emergency opening always possible, even if a key is inserted.
The emergency override key function is available for turning and metering keys as well as for master key systems or individual closings.

Product Details

Locked from the inside?
Not an obstacle in an emergency.

Your requirement:
You want to be able to unlock doors in an emergency or dangerous situations, even if a key is inserted on the inside. In addition, this key should only be used in an emergency and not be misused.

Principle of operation:
For example, in the case of a double cylinder, the emergency key function makes it possible to unlock the door from the opposite side if a key is inserted on one side of the door, regardless of the rotation of the inserted key. A default key cannot be used for this; instead, a separately managed and registered emergency key is required.
