Bristol University upgrades Access Security
A master keying systems across campus of Bristol University.


As part of an ongoing complete security upgrade throughout the campus, Bristol University has benefitted from Mul-T-lock’s MTL 600 master key suites, designed and installed by Guardian Security Systems in Bristol.
Bristol University is one of the most popular and successful universities in the UK, ranked 62nd in the world in the QS World University Rankings 2022.
Mul-T-Lock has worked closely with Guardian Security Systems in Bristol, supplying high-security MTL 600 suites to over 20 buildings across campus, all operated on a master key suite basis.
Says Antony Blundal, Security Services Manager (Systems) at Bristol University: “University premises present a number of security challenges due to the open nature of the campus sites. There are different access requirements across all the facilities to consider.
“Working closely with Guardian Security Systems and Mul-T-Lock we developed a specification using MTL 600, which offers high security and is flexible to accommodate these issues and remain cost-effective. The master key operation is invaluable to keep maintenance to a minimum and the patent protection allows us better control of how many key copies are in existence.”
Patent protected until 2032, MTL 600 presents a superior locking solution, with a combination of several technological elements to create strong resistance against different types of lock manipulation.
The high-security solution is available in various formats, to allow Guardian Security Systems to create master keying systems with different locking products across campus, including a wide range of cylinders, padlocks and locks, providing necessary protection and maximum convenience.
Ken Ham of Guardian Security Systems in Bristol commented: “MTL 600 uses the latest design technology and highly automated production techniques to deliver precision engineering with unparalleled performance. This is why it was particularly suitable for Bristol University, who we worked with to design, build and maintain the master key suites across campus to ensure high-quality security, whilst also providing necessary access for staff and students.”
Ian Thresher, Regional Sales Manager of Mul-T-Lock added: “The changing nature of the university ‘ecosystem’ in the UK, with significant developments such as rising tuition fees has many implications, including consequences for the safety and security of students, staff and the public.
“The legal and reputational issues arising from any failure to protect and secure people, physical assets and information data, are also increasingly severe. Hence, it is integral for suppliers like Mul-T-Lock and Guardian Security Systems to work closely with universities like Bristol, to understand the bespoke security requirements and install the best solution, such as MTL 600 to protect all those who attend.”
