1.
Exterior doors are solid core doors that are 1 3/8 inches thick
and are secured by dead-bolt locks. Dead-bolt locks must lock with
a minimum bolt lock throw of one inch that penetrates a metal strike
plate. If the door secured by the dead-bolt lock has breakable glass
within 40 inches of the lock, the lock must be key-operated from
both sides unless prohibited by life safety codes.
2.
Metal doors are secured by dead-bolt locks as described above.
3.
Double doors meet the specifications for exterior doors as listed
above, have the inactive door secured by header and threshold bolts
that penetrate metal strike plates, and in case of glass located
within 40 inches of header and threshold bolts, have the bolts flush-mounted
in the edge of the door.
4.
Sliding glass doors are secured by secondary locking devices to
prevent lifting and prying.
5.
Dutch doors have concealed flush-bolt locking devices to interlock
upper and lower halves and are secure by a dead-bolt lock as described
above.
6.
Garage doors are equipped with key-operated locking devices.
7.
Windows are secured by auxiliary locking devices. An auxiliary locking
device required by this section must include screws, wooden dowels,
pinning devices, and key-operated locks. In areas in which life
safety codes permit, metal bars or grating, if mounted to prevent
removal, may be substituted for auxiliary locking devices. Jalousie
or louvered windows do not meet specifications of this section unless
they have metal grating mounted as provided for above.
