10、nced in Section 2.5.General5.1 NFPA101 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 label designating
11、them as“fire exit hardware.”This means they have beeninvestigated for both fire resistance and panic.Exit devicesused on non-fire doors require a listing for panic.These labels1This practice is under the jurisdiction of ASTM Committee F12 on SecuritySystems and Equipmentand is the direct responsibil
