Front doors in shared buildings

Issue of contention: locking up at night

The number of newly built apartments in shared buildings surpassed the number of single and two-family homes in 2015 with the number of single-family homes sinking in large cities in particular. In Germany, the average apartment building is 42 years old, with many going without any form of modernisation for decades. The building entrance doors are often not in line with the latest technology and many tenants don’t know just what kind of products are available in door security today. 

Apartment tenants in shared buildings have perhaps already encountered the dilemma: should the front entrance be locked at night or not? Locking the door is always the safest solution to protect against uninvited guests. But what if people need to leave the building quickly in the event of danger and there’s no key to hand? Or forgetting to lock the door may even spark a dispute among the community of tenants. There is a simple solution that can provide security while saving energy costs: the automatic multipoint locking system. 

Secure automatic locks – keep your neighbours happy

Automatic locking systems have already established themselves as the standard in sophisticated door construction. Their automatic function provides reliable locking and protects against uninvited guests. Simply pull the door shut and the secondary locks at the top and bottom lock fully automatically – you don’t have to lift a finger.   

The door can then be opened easily from the inside using the handle. Opening from the outside requires a cylinder key. The permanent three-point locking system also protects against door warping and offers long-lasting seal tightness.

Another plus: Equipping the front door with a motorised automatic lock allows users to open doors using an access control system or via an intercom system from the inside. Integrating access controls, such as finger scanners or cloud access solutions, offers more convenience and increased security. The doors can also be optionally opened via radio (e.g. using radio key) for selected persons. 

With an automatic multipoint locking system, the door is securely locked at all times – the days of tedious locking up at night are over. Those who still like to lock up at night, e.g. because there is only one mortise lock available, should note the following.

Court decision: Entrance doors to shared buildings must not be locked!

Housing regulations for many shared buildings state: “The front entrance must be locked between 22:00 and 6:00.” This provides an increased sense of security as it prevents any potential break-ins. However, this obligation to lock the door is both ineffective and illegal. This was the decision of the Frankfurt am Main district court (Case no. 2-13 S 127/12, 12 May 2015).

According to the decision, entrances cannot be locked where escape by residents/visitors in the event of a fire or other emergency situation would only be possible using a key, as this is often not at hand in panic situations. The door must only be locked if it can be opened from the inside without a key.

Special panic locks for emergency exits and escape routes meet this requirement. FUHR offers a wide range of solutions here for all security and convenience needs: from panic mortise locks and panic multipoint locking systems to fully motorised multipoint locking systems with built-in panic function.

No panic locking system? No problem:

Clever retrofitting solution

The bolt lock set from FUHR is specially designed for entrance doors for shared buildings where there is no panic locking system. The lock stops and cover cap for the strike plate mean that the main bolt can no longer be locked out – the door is locked via the secondary lock. The door can therefore be opened at any time using the inside handle, ensuring safe escape in the event of an emergency. 

The set includes lock stop, cover cap for strike plate, and sticker for bolt and door. All FUHR automatic locks from the autosafe 833/835 and autotronic 834/836 series can be easily retrofitted with the bolt lock.

Accessories for door security in shared buildings

FUHR E-Öffner

Electric strikes

Electric strikes ensure convenient door opening from the inside. Combined with an intercom system, users can comfortably determine who is at their door. Users can then grant access at just the push of a button and without having to get up and go to the door.

Dog bolts

It’s not just the closing side of the door leaf that is important when it comes to break-in protection. The opening side is also crucial. As well as sturdy door hinges, an additional bolt on the opening side makes removing the door more difficult as the frame and leaf parts interlock. This is particularly important for doors that open outwards. Here, the hinges are on the outside, making them an easier target for burglars.

Access control systems

Finger scanners for keyless opening are very popular for private front doors. But that’s not all they’re good for – access control via radio fingerprint scanners, transponders or keypads are also a great alternative to conventional cylinder keys in shared buildings or for SMEs. This allows users to grant access authorisations for selected groups and limit access via timers. Authorisation for certain rooms or building sections can also be set up. Misplaced transponders or no longer authorised persons can be easily blocked without having to exchange the whole lock.
