FIRE SAFETY & SECURITY • 55 However, even where fire doors and their hardware meet the fire regulations there is also a need to comply with other building regulations, specifically access requirements. These stipulations under the building regulations are detailed in Approved Document M in England and Wales, Section 3 in Scotland and Part R in Northern Ireland. These regulations state that “…a door set must produce an opening force of below 30N between 0° and 30° degrees and below 22.5N between 30° and 60° degrees.” It is important to note that the requirement is stated in relation to the door ‘set’ and not simply the door closer. While this accounts for a significant part of the opening forces, the resistance effect of other ironmongery should also be considered. Manufacturers should be able to provide Torque Curve data for the products, this will show the forces throughout the opening and closing cycle in Newton Metres from initial opening through to 60° and beyond. From this the tolerances for resistance from other fitted items – such as door seals and hinges can be calculated. However, a number of factors can affect the installed efficiency of a door set and a manufacturer cannot guarantee that performance figures produced during testing will be replicated on site. For this reason, adjustable power door closers are recommended by BS8300 to allow changes to be made on site to offset the differences between tested and installed performance. An alternative approach to meeting both areas of legislation is electro- magnetic hold open door solutions. These controls allow doors to be held open during normal use and close automatically upon activation of the fire alarm, or in the event of a loss of power. This helps to improve ease of access through the building while still providing protection in the event of a fire. Finally, in addition to correct specification and installation, it is also vital that a regular maintenance schedule is established to ensure that the performance of the products and the installation as a whole remains compliant. Despite the importance of fire doors, they are commonly misused or mismanaged throughout their LOCKSMITHJOURNAL.CO.UK | NOV/DEC 2017 lifecycle. Aside from damage and poor maintenance that would compromise the door’s effectiveness, fire doors are often propped open rendering them entirely ineffective in the event of a fire. Financial pressures can make it tempting to postpone or cancel what is perceived as non-essential maintenance and servicing. However, when it comes to door solutions, these planned services will help to ensure continued compliance and system longevity – providing long- term savings in addition to peace of mind. When it comes to fire doors, compliance with all relevant legislation will help provide the essential protection for the building and its occupants. The recommended approach to achieving this compliance is by ensuring that doors and door hardware are correctly specified, sourced from reputable suppliers with clear test evidence and a Declaration of Performance, and then installed and maintained by specialists.
