Fire door closers are necessary to ensuring that fire doors operate effectively. You can find two main forms of closers available in the marketplace namely manual and automatic. Modern variations on the automatic closer include wireless solutions that offer more flexibility than standard fire doors.
Manual Door Closers
The type of closer employed is determined by a number of factors. They can be surface mounted, concealed in the frame or concealed in the floor قیمت آرام بند. These factors are partly determined by aesthetic considerations, although in some cases concealed closers are helpful to guard against vandalism. Manual types operate on a spring mechanism. The spring is loaded as the door is opened and then a spring releases after the door is opened, closing behind the user. Manual doors are available to considerable abuse and are commonly found propped or wedged open. While protective items certainly are a simple and very efficient bar to the spread of smoke and fire, a home that’s been propped open is immediately redundant and may result in disaster.
Automatic Door Closers
They are common in many buildings and operate using either a button to open them or a sensor system, which detects motion, opening to allow access. Both will close automatically using sensors to detect motion. Automatic doors of this type usually feature a press button at a height ideal for wheelchair users and not merely offer excellent fire protection but can help make a building accessible for the disabled. Again, they may be at the mercy of abuse and may be propped open, although this is less common than with the manual type.
With the widespread usage of wireless technology automatic fire door closers have become more robust and resistant to abuse. A computerized closer can simply be fitted to a home that operates each time a fire alarm sounds. This allows for a home to be left open to allow for ventilation and ease of access on top of a building. When required the door automatically springs into action. This sort of fire door is increasingly popular and they may be fitted easily and quickly to any existing doors without the necessity for complex wiring or building alterations.
Fire doors save lives. Ensuring the right ones are fitted for a building is essential, but of equal importance is ensuring they are used effectively and not abused. Correct usage of closers can make all the difference to a company in the case of a fire breaking out, reducing the damage due to smoke and fire and also the chance of injury or death.
