FAQ

What is a European-profile cylinder?

It is the most used cylinder in locks. It features standardized sizes and dimensional tolerances to allow interchangeability in locks by different manufacturers.

What is an anti-drill cylinder?

An Anti-drill cylinder is provided with protective devices which make drilling more difficult and longer; these devices may be pins or internal carbonitrided elements or case-hardened steel elements.

What is an anti-tear cylinder?

An anti-tear cylinder is provided with protective devices which make tearing more difficult and longer.

What is the term Bumping associated to a cylinder?

Bumping is a picking technique to open cylinders. A bump key is inserted into the cylinder and is used as a tensor. The key is then knocked with any  rigid object, the pins jump up and the cylinder opens.

I lost all my keys and I have to replace the cylinder, how can I do it?

Some cylinders need the key in order to be disassembled. In this case, if they have a property card with a code, the key can be reproduced in a service centre even without the original. Otherwise, you will have to pick the cylinder.

What is a construction site cylinder?

It is a cylinder having a key which can only be used during the building stage (first-use key), and a bunch of sealed keys handed over to the end user (second-use key). The insertion of the second-use key disables the first –use key (the process is not reversible).

What is a recodable cylinder?

It is a cylinder provided with one or two bunches of sealed keys (1st, 2nd and 3rd use).

The 1st bunch is normally used to open the cylinder.

Should any of the keys in the 1st bunch get lost,  security is guaranteed using a key from the 2nd bunch. The insertion of the second-use key disables the first –use key (the process is not reversible).

If a cylinder is provided with the 3rd bunch, the lock can be further recoded.

Which voltage must be used for an electric lock?

Most electric locks operates with a 12 volt Ac or Dc, but there are also 24 volt versions. Carefully read the instructions.

Can an electric lock be opened if the voltage runs out?

Electric locks are generally provided with a cylinder or handle for mechanical opening. According to the application, the cylinder and the handle could be only internal, only external or both.

Which is the difference between a flat forend and a “U” forend?

The forend is the part of the lock which is seen when the door is opened and is used for fixing.

The choice of the two forends depends on the type of profile where they are fixed or on the type of supports offered by the profile. Generally, the U forend is used in multi-point locks and for door-type profiles.

What are MK systems?

MK systems are manufactured with customized cylinders. They can be:

MK systems, commonly known as passe-partout, where a set of individual cylinders can be opened both by their own keys and by a single key called master key.

CK systems, where one or more cylinders (called central cylinders), are operated by different keys.

How many cylinders can be made from each master key?

It depends on the type of cylinder, since each cylinder features a limited quantity of resources for the development; moreover the system complexity reduces the utmost development capacity as well.

Can you add further cylinders to an existing system?

A part of resources is generally kept for further development. When these resources are run out no other cylinder can be added.

What is a striking plate?

It is the component where the bolt of the lock extends into when the door is closed. It may be of different shapes, materials and finishes according to the type of frame and lock.

Why is the striking plate adjusted?

Adjustable striking plates have been designed to meet the installation requirements according to the different aluminium frames; a few articles which can be adjusted to many profiles. 

Striking plates can be adjusted to the lock after installing the door, ensuring a precise locking. 

Which standard regulates door closers?

Door closers are regulated by EN1154.

What is a panic exit device?

It is a type of locking installed on emergency doors. It must ensure exit from the room in any condition, by simply operating the push bar. These devices must comply with EN1125 standards and must be EC marked.

Which standards regulate emergency exits?

EN 1125

Standard concerning panic exits with devices operated by a horizontal bar (traditional lever- or push-bars).  Devices installed in places with people or audience not trained for emergency procedures: theatres, cinemas, buildings for sporting activities and so on.

EN 179

Standard concerning panic exits operated by handle, plate or lever.  Devices installed in places with people or audience trained for emergency procedures: offices, power plants and so on.

What is a product certification?

It is a voluntary certification where an independent body assesses and certifies that the technical-productive stages of panic exit devices comply with the relevant European standard.

Can a Pad device be assembled in a public place?

PAD devices complies to EN 179 standard.

In Italy, their application is limited by a law enacted on November 3rd, 2004, concerning the activities subject to the control of the firefighting authorities in order to issue a fire prevention certificate.

They can be installed if:

  • The activity is open to the public and the door is usable by less than 10 people.
  • The activity is not open to the public and the door is usable by 9 to 26 people.
Can the Push panic exit device be shortened?

All devices belonging to this series can be shortened. The minimum size varies according to the device product family.

What is a microswitch and what is it used for?

It is an additional device which, inserted into the panic exit device, allows to signal, even from a distance, the operation of the push bar (door opening); the microswitch must be connected to a sound, light device or other devices.

What is the Bolt system?

What is the Bolt system?

It is a new patented keep for panic exit devices much more secure than traditional latches since it uses self-locking and anti-breaking Ø 14 mm top and bottom points.

Can panic exit devices be assembled on PVC profiles?

The standard keeps are not suitable for PVC profiles, yet they can be bought separately as accessories.
