Fire door closers are necessary to ensuring that fire doors operate effectively. There are two main forms of closers available available on the market 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 kind of closer employed will depend on several 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 beneficial to guard against vandalism. Manual types operate on a spring mechanism. The spring is loaded as the door is opened and then the spring releases after the door is opened, closing behind the user. Manual doors are ready to accept considerable abuse and are commonly found propped or wedged open. While protective items are a simple and quite effective bar to the spread of smoke and fire, a home that has been propped open is immediately redundant and can lead to disaster.
Automatic Door Closers
They are common in several buildings and operate using either a key 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 kind usually feature a press button at a height suitable for wheelchair users and not just offer excellent fire protection but can help make a building accessible for the disabled. Again, they can be subject to abuse and may be propped open, although this really is less common than with the manual type.
With the widespread utilization of wireless technology automatic fire door closers have be robust and resistant to abuse. A computerized closer can very quickly 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 within a building. When required the door automatically springs into action. This sort of fire door is increasingly popular and they can be fitted easily and quickly to any existing doors without the need for complex wiring or building alterations.
Fire doors save lives. Ensuring the correct ones are fitted for a building is vital, but of equal importance is ensuring they’re used effectively and not abused. Correct utilization of closers may make most of the difference to a company in case of a fire breaking out, reducing the damage caused by smoke and fire and also the danger of injury or death.
