Fire doors are a weak point in any fire barrier because their primary function is to allow traffic to pass from one room into another. It is therefore important for fire doors to be kept closed when not in use. Fire doors are required to be self-closing and therefore have fire door closers fitted, which can pose significant obstacles to the young, elderly, infirm or disabled. Experience shows that convenience often takes precedence over safety and building users may seek to disable or otherwise undermine devices that inconvenience them in carrying out their work. Doors are often held open by wedges or fire extinguishers, which is not only unsafe but also illegal. d. The condition of the fire-resisting glass and glazing system in the door panels, and any associated side or over panels forming part of the doorset, retains their ability to resist the spread of fire and smoke. These door holders can be powered by batteries, from the mains, or from nearby power supply units (PSU) rated at 12V or 24V DC. It is generally recommended to install them at the top of the door to prevent warping caused by the door closer pulling against the electromagnet. Battery-powered versions typically use an acoustic sensor to listen for an alarm sounder while wired models will often be connected directly to the fire alarm panel.

Requirements and test methodsFire door retainers (also called fire door holders) allow occupants to hold fire doors open in a legal and safe manner, removing the temptation to wedge the doors open. These devices hold the doors open in the day-to-day running of the building but will release the fire doors if there is a fire, allowing the fire door closers to do their job. Twist handle jar openers are popular with people who suffer arthritis. A ratchet-type mechanism grips the top of the lid with an adjustable metal clamp. An easy-to-grip handle extends from the clamp and opens the jar when you twist it. Both hands are needed in this action, as one hand must hold the jar. BS EN 1155: 1997 Building hardware. Electrically powered hold-open devices for swing doors. Requirements and test methods * Mechanical performance of a product is just as important as the fire performance. Using a CE-marked door closer ensures satisfactory mechanical performance. A door closer that is CE marked shows the product is mechanically sound to perform the function of closing a fire door and that it has been subjected to a fire test.
Devices intended for use by the general public should be CE Marked to BS EN 1125: 2008 – Panic exit devices operated by a horizontal bar, and preferably provided with additional product certification by an approved third-party certification body.

If a building has untrained occupants or the number of trained occupants exceeds 60 people, panic devices with either a push bar or touch bar must be used. Push bars and touch pads have a larger surface area and are more easily located and operated in a fire or panic situation. These must be CE marked to BS EN 1125.
The devices must be tested weekly, in association with the testing of the fire alarm system, and maintained in accordance with the manufacturer’s instructions. The regular release also helps to prevent warping of the fire door leaf. A record should be kept of all testing and maintenance activities. Doors fitted with such devices should be kept closed during periods when the fire alarm system is isolated for maintenance purposes. Wherever possible the fixing of a letter plate to a fire-resisting door should be avoided. Prime consideration should be given to installing the letter plate elsewhere.

Jar openers that provide leverage allow you to apply greater force with the help of a handle or some other type of extension. The added distance of the lever means you don’t need a lot of strength to twist off the lid. The mechanics of the design amplify the force you exert on the jar, reducing your need for physical strength.

For fire door fittings intended for use against fire, markings will be the easiest method to demonstrate compliance. The Building Control Officer or other approved inspectors or a Trading Standards Officer, however, will require proof of this compliance. Across the UK construction industry and in Europe, construction products are being tested to new EN Standards to ensure that fire safety and performance requirements are met in future building projects. Door hardware will eventually have 21 new EN Standards. For many ironmongery items you will need to ensure that only marked products are used on all fire doors, smoke control doors and escape doors. Fire Door Closers
