A master suite may be required in multiple occupancy buildings, such as a block of flats or office buildings. The master key will open all cylinders, a sub-master key opens only a set of cylinders, while the key of the ‘child’ cylinder will only open the cylinder to which it is matched.
There are three levels of cylinders based on the key security and complexity of the Master Key system, choices of which level is most appropriate should be based on the following:
Product Features:
Tigris
Plus
Omega
The Tigris MasterKey systems are made to order, delivery time is based upon the size and complexity of the system and will be advised on order. Most orders take 3 - 5 working days on receipt of order.
TS 007 is a security standard relating to the door handle and cylinder combination used on a door. To achieve TS 007 status, the combination used must total 3 stars.
A cylinder can achieve either 1 or 3 star classification, where as a door handle can only ever achieve 2 stars.
Therefore, it is possible to achieve 3 star accreditation by combining a 1 star cylinder with a 2 star door handle. Or, just using a 3 star cylinder alongside an unaccredited door handle. See our simple diagram below.
Achieving TS007 is vital in order to pass any door to PAS 24 or achieve Secured by Design.
Anti-Snap – the cylinder has a section or sections, often called a sacrificial cut, either side of the central lock mechanism that will come away if the cylinder was to be attacked from the outside, however leaving the remainder of the cylinder mechanism intact and locked.
Anti-Pick – the top half of the pin stack inside the cylinder are designed to include a mushroom shape or indent. Therefore, if something was used to pick the cylinder it would catch on the pins and prevent the cylinder from unlocking.
Anti-Bump – cylinders are designed to have more pins (generally 6) and a shallow pin stack. By doing this it means that if a bump key was knocked into the cylinder, the pins would not jump up meaning the cylinder could not be bumped.
Anti-Plug/Core Extraction – the cylinder has strengthened steel circlips that hold the cylinder in place so the core cannot be extracted from the cylinder.
Anti-Drill – the cylinder has plates and pins built in and this prevents the cylinder core being turned if the pin stack was attacked by a drill. It is designed to break the drill bit and protect the integrity of the cylinder to prevent entry.
Restricted profile cylinders / key systems are non-duplicable, meaning it’s impossible to purchase blank keys in the market and create fraudulent keys. These cylinders provide a higher level of security.
On the other hand, open profile cylinders mean that any key cutter on the market can make replacement cuts and the cylinders can then be mastered from this. This can sometimes be a homeowner’s preference as it is easier to get additional keys cut.
BS EN 1303 is a British Standard relating to cylinders. It is broken down into 8 digits and ensures that the cylinders are tested to the highest standard. The 8 digits are; Category of Use, Durability, Test Door Mass, Fire Resistance, Safety, Corrosion and Temperature Resistance, Key Related Security and Attack Resistance.
Cylinders are graded based on this criteria.
Step 1: Open the door and loosen the door handle fixing screws slightly, or remove them and the handles completely
Step 2: Unscrew and remove the cylinder fixing screw
Step 3: Put the key in the cylinder and slightly turn it until the cam tongue is aligned, once this is aligned you can pull the cylinder out, (generally the key will point to around 5 to or 5 past on a clock face)
Step 4: Replace with the new cylinder and then repeat the process in reverse order
A free movement cylinder allows a key to operate the cylinder even when there is already a key inserted in the other end. These cylinders are for use on emergency exit door lock kits such as the FUHR 870 and 871. This function ensures that when the panic bar or panic lever is pushed the cam will rotate freely and allow use at any time.
This type of cylinder is also recommended for use with the FUHR 881 Electromechanical Door Lock.
Step 1: Measure the overall length from the bottom part of the cylinder
Step 2: Measure from the centre screw hole to each end, these two measurements combined should be equal to the overall length
OR
Step 1: Measure from the centre screw hole on the door lock to the face end of the cylinder on each side, these two measurements will be equal to the overall length
This cylinder key system is used where you need to provide different levels of access to different people within a building. For example, a system could allow for cleaning staff to be able to unlock all cylinders in an office, but only allow individuals to unlock their personal office door.
