Did you know that 80% of burglars go through the front door? So to provide a simple but effective protection of this door, the multipoint lock seems to be the ideal solution. It activates various locking points (3 to 7) with a single key, which ensures enhanced security for your front door.
The characteristics of a multi-point lock
The multipoint lock kits consist of a lock, a set of linkages and a rod guide or band, strikes, a laying template and possibly reinforcements hinges. The door can be opened both inwards and outwards, depending on the travel available. In addition, there are several types of closures: draw in the form of a zipper that can be manipulated with a single finger and taking up less space or with a handle, which can match the style of the front door. The shape of the lock can be horizontal for standard doors, or vertical for doors with moldings and wider. This means that for doors over 2.10 m high, a lock with 5 locking points is recommended.
The different types of multipoint locks
There are different types of multipoint locks that sometimes require a specific pose. The more locking points, the stronger the door. In any case, you need a door of good quality, thick enough not to break at the first attempt of break-in. Applied models are often used when replacing locks, but also in new homes. They fit on most input spans, so it is not essential to change the door for the installation of this type of lock. Here, the linkage can be apparent, either bandeau, equipped with a metal cladding, or faired and equipped with a metal strip over the entire height to strengthen the amount of the door. In addition, for added security the built-in or recessed installation hides in the thickness of the door, but does not provide additional security.
The security elements of a multi-point lock
The cylinder and the key are the most important elements to guarantee the security of a lock. The cylinder is the mechanical part of the lock receiving the key (also called "gun"). It is chosen according to the level of security sought. The most important is the number of pins in the cylinder (lock safety block). These are small cylindrical sliding parts that serve to block the opening. The more the cylinder of the lock is equipped with pins (5 to 15 pins depending on the model), the harder it is to open the lock by picking. The effectiveness of the multi-point lock can be increased depending on the level of protection of the cylinder:
Antichrusting plus the technology of the cylinder is complex (pins, pumps) and prevents special tools to enter, the more difficult and long picking.
Anti-piercing: the addition of a rotating element protects the pins in case of drilling. It turns the drill in the vacuum and prevents it from advancing in the cylinder.
Anticasse: with a reinforced part that protrudes from the cylinder to prevent it being pulled and broken by a clamp.
As for the keys, they can be notched, the most widespread for a standard level of safety, but also flat, reversible, ball or countersunk which allows to go in all directions in the cylinder or pump, claiming a movement pressure to open the door.
Finally, before choosing a lock, it is essential to ensure that it is well certified by the APEC label, a standard that assesses resistance to burglary attempts by security devices. It is often required by insurance and issued by an independent institute, the CNPP (National Center for Prevention and Protection). Engraved on the central bolt, keys and cylinder locks and locks, the A2P label comes with 1, 2 or 3 stars depending on the minimum time of burglary resistance:
1st level of security "1 star": takes less than 5 minutes against an attempted break-in
Good security level the "2 stars" holds 10 minutes
With a high level of security, the "3 stars" holds at least 15 minutes.
