DOOR CLOSERS & CONTROLS
Relcross Door Control - LCN 4000 Series
PROBLEM SOLVING AT JOHN FERNELEY COLLEGE
Standing impressively on a hillside above Melton Mowbray , Leicestershire , the John Ferneley College is an 11-16 Secondary Academy - part of the Mowbray Education Trust . Named after local resident and leading equine painter of the early nineteenth century , the College has performed extremely well in academic terms over the past few years , with GCSE results in the top 10 % of schools nationally .
Cast Iron Guarantee
LCN 4000 series materials include high-strength castiron cylinders , forged steel arms , double heat-treated steel pinions and full complement , low friction bearings for rugged reliability in high-traffic installations . Precise hydraulic control is provided by an all weather fluid that eliminates the need for seasonal adjustments . Should adjustment be needed at installation , the LCN ® Fast™ Power Adjust system makes this quick and easy .
Further , many closer manufacturers use inexpensive oil tempered springs but we know that such a spring can lose up to 20 % of its power after a few thousand cycles . The chrome silicone springs used in our closers have the strength to perform beyond 10 million cycles .
Extra Duty Performance The school is divided into three separate learning zones with three sets of double doors leading through from the main corridor into each zone . At intervals throughout the school day large numbers
of people are using the doors simultaneously - some more intent on arriving at their destination than treating the doors ( and hardware ) with due respect . This is a typically harsh environment where only proven heavy duty door control will survive .
As is often the case , the original door control specification proved to be inadequate , with fire doors failing to close properly after a short period . Fire and life safety is , of course , a priority and Estates Manager Jeff Challis turned to the experts - Relcross Door Controls - who recommended the LCN 4000 series heavy duty closer as an appropriate solution - specifically the 4111 variant with extra duty forged steel arms .
