1、Designation: F 571 87 (Reapproved 2001)Standard Practice forInstallation of Exit Devices in Security Areas1This standard is issued under the fixed designation F 571; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last
2、revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice provides information for the installation ofexit devices used in areas of security to achieve the greatestse

10、cuments referenced in Section 2.5. General5.1 NFPA 101 and many building codes require exit devicesin certain locations and should be consulted.5.2 UL 305 and BHMA A156.3 have specific requirementsfor the performance of exit devices and should be consulted.5.3 Exit devices for fire doors require a l

These labelsand listings shall be by a nationally recognized, independenttesting laboratory. A periodic examination

Installation Guidelines6.1 Doors and Frames:6.1.1 Doors and frames installed in locations where exitdevices are used for purposes of security should have minimumclearances at the head, jambs, and meeting stiles (if in
13、 pairs)and at a threshold or sill.1This practice is under the jurisdiction of ASTM Committee F12 on SecuritySystems and Equipment, and is the direct responsibility of Subcommittee F12.50 onLocking Devices.Current edition approved Aug. 28, 1987.

16、ned in Test Methods F 476. Whereapplicable, doors and frames should be reinforced to receivefasteners described in 6.8.6.2 Associated Hardware:6.2.1 Hinges or pivots used to hang doors should be of atype where the unauthorized separation of the hinge side of thedoor from the frame is hindered. This
17、can be achieved byincluding design features in which the hinge leaves are lockedtogether.6.2.2 Doors should be self-closing so that when the exitdevice is activated from the egress side, the door will auto-matically return to the closed and locked position and not stayopen. This can be achieved thro
18、ugh the use of door closingdevices.6.2.3 Electric strikes (see BHMAA156.5 and UL 1034) maybe used for security areas. These can be arranged to signal anunlocked condition or an open door. Some electric strikes maynot be used on fire doors.6.2.4 Astragals can add to the security of a pair of doors by
19、making it more difficult to probe the clearance at the meetingstiles and trip the opening mechanism. However, it is importantthat the astragals do not inhibit the independent action of eachleaf if both leaves are active.6.3 Exit Device Functions:6.3.1 Functions of exit devices range from those havin
