Article 4 — Nonresidential

(a)

General. Security methods shall not create a hazard to life by obstructing any means of egress or any opening which is classified as an emergency exiting facility by local ordinance. Security provisions shall not supersede the safety requirements relative to latching or locking devices on exit doors which would be contrary to the provision of Chapter 33 of the Uniform Building Code nor shall the provisions of this chapter be construed to waive any other provisions of the ordinance codified in this chapter. In the event of a conflict of code provisions pertaining to life safety considerations, the adopted edition of the Uniform Building Code shall prevail.

(b)

Type of Lock or Latch. Exit doors shall be openable from the inside without the use of a key or any special knowledge or effort. This requirement shall not apply to exterior exit doors in a Group B or Group A Division 3 Occupancy, as defined by the Uniform Building Code, if there is a readily visible, durable sign on or adjacent to the door stating "THIS DOOR TO REMAIN UNLOCKED DURING BUSINESS HOURS." The sign shall be in letters not less than one inch high on a contrasting background. The use of this exception may be revoked by the enforcing authority for cause.

(c)

Manually operated edge - or surface - mounted flush bolts and surface bolts are prohibited. When exit doors are used in pairs and approved automatic flush bolts are used, the door leaf having the automatic flush bolts shall have no door knob or surface-mounted hardware. The unlatching of any leaf shall not require more than one operation. Double keyed, double cylinder dead bolts are not permitted.

(d)

Single-solid core wood doors or hollow sheet metal doors shall be a minimum of one and three-fourths ( 13/4 ″) inch thick and shall be secured with a single-cylinder deadbolt lock with a minimum throw of one inch. When wooden jambs are used, strike plates shall be secured with two and one-half (2-½″) inch wood screws. Door jambs shall be installed with solid backing in such a manner that no voids exist between the strike side of the jamb and the frame opening for a vertical distance of six (6″) inches each side of the strike. On pairs of doors, the active leaf shall be secured with the type of lock required for single doors. The inactive leaf shall be equipped with automatic flush extension bolts protected by hardened material with a minimum throw of three-fourths (¾″) inch at head and foot and shall have no door knob or surface- mounted hardware. Multiple point locks, cylinder activated from the active leaf and satisfying the requirements listed above, may be used in lieu of flushbolts.

Any single or pair of doors requiring locking at the bottom or top rail shall have locks with a minimum of one throw bolt at both the top and bottom rails.

The method of securing shall be a case hardened steel padlock, locking at both heel and toe of the shackle. The padlock shall be secured to a steel U-joint mounted in the cement floor or secured to angle iron which is mounted directly to the building structure. Masonite panels in such doors will not exceed eight (8″) inches by twelve (12″) inches and will be located so that they are no closer than three (3′) feet to any locking device.
