FIRESAFETY & SECURITY
ADJUSTABLE BACKCHECK
“ In some cases , a fire door may be opening too quickly and violently and when poorly adjusted , this can leave the door to jam on the closing cycle . To prevent damage to the door or injury to persons standing behind it , we recommend adjusting the backcheck . Doing so will provide a cushioning effect , slowing the door down which is optimal for active building environments such as schools . Even after adjusting the closer , it ’ s always worth using doorstops .”
ADJUSTABLE DELAYED ACTION “ A prolonged closing action is useful for busy environments such as schools , hospitals and care homes – helping users pass through in adequate time . By adjusting the delayed action , the speed of which the door closes can be set slower , giving people extra time to pass through the doorway . Adjustable timing is set between 70 degrees and 120 degrees . However , maximum delay permissible on a a fire door should take no longer than 25 seconds to complete its closing cycle .”
ADJUSTABLE HOLD-OPEN
“ Although mechanical hold open door closers are for use on non-fire doors only , electromagnetic doors can safely implement hold-open door closers under fire safety standards .
“ A fully functional fire door closer is a prerequisite for comprehensive fire safety . And so , when it comes to the installation and maintenance of fire door closers , it ’ s never right to risk building safety or noncompliance .
“ To take the first step is to understand where fire safety may be compromised and what door closer adjustments are required to remedy those issues . Because only when a closer is operating at optimal speed and strength is a fire door able to offer essential protection against the elements .”
