Patient Security From Union’s Masterkey System


UNION, part of ASSA ABLOY Security Solutions, a division of ASSA ABLOY, has supplied its KeyULTRA™ masterkey system for over 800 doors at a medium secure psychiatric unit in Leicester.

Founded in 1983, Arnold Lodge, part of Nottinghamshire Healthcare, was one of the UK’s first purpose built medium secure units to become operational. The unit provides an in-patient Forensic Psychiatric Service to adults who are unable to be treated through General Psychiatric Services, working closely with the Criminal Justice System.

Lincoln Security installed 800 of UNION’s KeyULTRA™ masterkey cylinders, throughout the development, to help manage the facility’s security and access control requirements.

In addition, to standard single and double Euro Profile cylinders, euro thumbturn with clutch release functionality were also installed at Arnold Lodge for added patient safety.

Ideal for mental health applications, the clutch release function prevents a patient from barricading themselves in their room. The clutch is disengaged by inserting a key from the outside, granting access to authorised, key-holding personnel, regardless of whether the door is locked or being held from the inside. 

Jason Healy, Project Manager for security specialists, Lincoln Security, said:

“Nottinghamshire Healthcare was keen to upgrade its existing UNION system, and having previously worked with KeyULTRA™, I was confident it was the best system for a project with such rigorous demands.

“UNION’s ability to deliver the high number of cylinders with specialist functions in a relatively short space of time, combined with its quality British manufacturing were key factors in its specification. This enabled us to deliver and install a fit for purpose system, on time and on budget.”

Simon Wilson, Regional Sales Manager for UNION, added:

“In using our experience of working within the health sector and working alongside a highly respected security company, like Lincoln Security, we have been able to supply a patent protected masterkey system that is tailored to fit the needs of the facility.”

KeyULTRA™ is a 6 pin masterkey cylinder that possesses one of the longest patents on the market, lasting until 2028, meaning that the cylinder and keys cannot be copied.

Designed with reliability and durability in mind, keyULTRA™ has been tested to 500,000 cycles and also has over half a million key differs. It has received the highest grades for key related security and attack resistance in relation to BS EN 1303:2005 when used in conjunction with a security escutcheon.
