Block lock: definition, function & tips for choosing

There are many ways to create a high level of building safety. One option is the so-called block lock. But what exactly is it? How does a block lock work? And what advantages does it offer? You can find the answers to these questions in the following article.

What is a block lock?

A block lock is a special additional lock that is mainly used in conjunction with an intrusion alarm system (EMA). If the alarm system is active, it is the task of the block lock to block the door– hence the name.

The purpose of this is to prevent unauthorized access. In addition, thanks to a block lock, the door cannot be locked if monitored entrances such as doors and windows are not closed. Thus, a block lock raises the security of the entire building to a whole new level.

How does a block lock work?

Since it is usually only an additional lock, the block lock complements the already installed door lock. In this way, it adds extra security to the locking system. In addition, this type of lock can also be installed independently. But how do block locks actually work?

A block lock is an electromechanical unit and is controlled electronically – for example with the help of a transponder. It keeps the locking mechanism in a blocked state until all doors and windows connected to the alarm system are closed, and the system does not detect unauthorized persons.

You activate a block lock from the outside. This prevents people with access authorization from manipulating the security system. To ensure that the block lock can fully fulfil its function, it is equipped with a bolt or bolt. This allows the lock to snap into place and achieve a strong lock. Due to this functionality, it is almost impossible to gain access without the right key.

Block locks usually do not have a visible keyhole –after all, this is not needed. Therefore, they can be discreetly and inconspicuously mounted behind door fittings or in the wall. This will protect you even more effectively against an attempted burglary.

It is true that a door equipped with a block lock cannot be opened easily. This also applies to all other doors and windows that are equipped with the alarm system. However, in order to ensure maximum safety, it is possible to open it in an emergency – for example in the event of a fire.

This is how a block lock is constructed

The structure of block locks is usually the same. The locks are located in a closed housing. Components such as a locking cylinder, a bolt and a striking plate are held together by connecting elements. But electronic components should not be missing either, for example:

• Cable
• Sensor
• Engine
• Relay

 In many cases, a small circuit board for the control electronics is also installed. In this way, block locks can be controlled electronically.

What are the advantages of a block lock?

Block locks offer a number of advantages. Therefore, they are actively used in various areas.

• Security: Arguably the most obvious benefit is the high level of security achieved by using a block lock. They are robust and resistant locks that are not so easy to crack.
• Flexibility: Block locks can be installed as stand-alone locks or as an addition to the existing lock.
• A wide range of applications: Whether in offices, industrial plants, residential buildings or public facilities – block locks are very popular in various areas. They are an excellent option in both private and business environments.
• Diverse features: There are many different types of block locks. They can be opened electronically, but the access medium is left to the building operator. RFID technology and PIN code keyboards are popular. Often, several variants are also combined with each other in order to benefit from the advantages of several options.

This means that block locks are considered a versatile and popular way to make buildings even more secure.

Which block lock is right for my needs?

Manufacturers such as BlueID offer a range of high-quality block locks for maximum security at home and in the company. But how do you find the block lock that fully meets your expectations and requirements? There are some criteria that you should take into account when choosing the best model for you.

Levels

As with other types of locks, block locks have different levels of security. Burglar alarm systems are also referred to as VdS classes. They evaluate how high the resistance to overcoming and sensitivity are. You can purchase block locks in exactly three VdS classes:

• Class A: Basic protection with low resistance and medium response sensitivity is provided.
• Class B: The resistance to overcoming is slightly higher than with Class A locks, but the sensitivity is still in the medium range.
• Class C: Block locks of security class C are the most secure. They offer comprehensive protection through very high sensitivity and a quick response to attempted break-ins.

In some shops, a certain class is mandatory. In addition, there are facilities in which there are very high values, so that a correspondingly higher security level is worthwhile. This applies to jewellers, among others.

Installation Environment & Integration

To make a block lock even more secure, you should pay attention to the environment in which it will be installed. Do you want your block lock to be installed outdoors? Then you need a weatherproof and particularly robust version. Indoors, these criteria are omitted – but visual aspects are usually in the foreground.

In order for the block lock to be integrated into the system, it must be compatible. Therefore, before purchasing, you should check whether you can easily combine the desired lock with the existing components. At BlueID you will find comprehensive solutions – tailored to your requirements.

Access option

PIN code or RFID transponder? Basically, the choice is yours. Pay attention to what is most convenient for users. In addition, this is also about the aspect of safety. Biometric systems such as fingerprints or facial recognition are usually considered more secure than traditional keys or even codes.

Specifications for block locks

If you want to install a block lock, you have to pay attention to the applicable regulations. Encryption monitoring of intrusion alarm systems is mandatory – regardless of whether the system is used in a private or commercial context. The block lock has a monitoring and control function. If the use of a locking device is prescribed, there are strict security requirements for doors and windows. Here, a resistance value according to RC 2 is often shown. This means that the frame and door leaf are certified in accordance with the DIN EN 1627 standard.

Result

Block locks are usually connected to the alarm system and are an excellent solution to improve building security. Thanks to a unique mechanism, doors can be securely locked to prevent unauthorized access. Because block locks are electronically controlled, they offer a number of great benefits.
