A total of 25 doorsets with a two-hour fire rating have replaced the 18-year old Martin Roberts doorsets that were in place throughout the lower ground floor and basement areas of the building – the name of which has not been disclosed due to security reasons.
The new doors have been designed to open automatically, as the older doors were subject to heavy use by service personnel including cleaning and maintenance and service staff as well as providing a thoroughfare for pallets and goods.
The company worked closely with Paul Stockham of Project Support Services who completed the site survey, supplied and installed the doorsets.
A spokesman for Ingersoll Rand said: “Martin Roberts steel doorsets are ideal for this kind of demanding situation where robust, long life solutions are required in the most extreme usage environments. Their mix of durability and high performance coupled with fire, acoustic and security performance and favourable life-cycle costs makes them a popular choice for specifiers.”
The Dor-O-Matic compact swing closer, a self-contained electromechanical device, “offers an exceptionally cost effective method of automating new or existing double leaf or single leaf swing doors,” the company said.
“With an overall height of 115mm and depth of 123mm, the compact swing is designed to aesthetically fit onto most existing profiles. The operator can be adapted on-site to suit a variety of door and frame widths, as the components are mounted onto an extruded backplate which gives lateral adjustment of the drive mechanisms to achieve perfect alignment of the operator to the opening.”
