  RELEASING SYSTEMS FOR SECURITY BARS IN DWELLINGS

  12-3-2.4.2 Escape. For the purposes of these requirements, escape refers to movement of occupants from the interior of a residential dwelling unit to a safe point outside of the dwelling unit during an emergency fire condition.

  12-3-2.4.3 Emergency means of escape. A passage independent of and remote from the primary means of escape that provides a means of travel from living and sleeping spaces inside a dwelling unit to the outside.

  12-3-2.4.4 Means of escape. A concept included in building codes that, in most cases, requires sleeping rooms and living areas in dwelling units to be provided with at least one primary means of escape and one secondary means of escape to the outside.

  12-3-2.4.5 Primary means of escape. A door, stairway or ramp providing a means of unobstructed travel from living spaces inside a dwelling unit to the outside at street or ground level.

  12-3-2.4.6 Security bars. For the purposes of these requirements, the term “security bars” includes “burglar bars” and refers to metal and other bars, grilles, grates and other barriers that are designed to provide security for doors and windows in dwelling units. The purpose of security bars, by their mere presence on a building, is to deter a potential forced entry into the dwelling.

When actuated by the occupant, the system allows the obstructions over the door or window to be moved so occupants can escape in the event of an emergency.

  12-3-1.2 These requirements only cover the ability of the releasing system to be manually activated from the interior of a dwelling unit by an occupant to affect an escape through the protected opening.

  12-3-1.3 These requirements cover releasing systems intended for use on the interior side of doors or windows in all climatic locations.

  12-3-1.4 These requirements do not evaluate the ability of the releasing system or obstructions to resist an external forced entry attack.

  12-3-1.5 These requirements do not evaluate the ability of the releasing system or obstructions to be opened or removed from the exterior of the residential dwelling unit by emergency response personnel during rescue operations.

  12-3-1.6 Products covered by these requirements are intended for installation in dwelling units to protect door and window openings that are designated by the California Building Standards Code to be used as the secondary means of escape from the living area.

  12-3-1.7 Products covered by these requirements are not intended to be used to protect doors in means of egress path for nonresidential occupancies, the common egress path of multifamily residential dwelling units or the primary means of egress path in a single-family dwelling unit.

  12-3-1.8 These requirements do not cover window guards or fall prevention devices that are intended to prevent falls from upper story windows.

  12-3-1.9 These requirements do not apply to storm doors and windows or light duty screens used for insect control.

  (c) Listing by approved listing agency. Listing by an approved listing agency shall not be construed as necessarily indicating compliance in all respects with the requirements of these Construction Standards and Performance Tests for Emergency Exit and Panic Hardware. The test report of the listing agency may be filed for review and after evaluation, if it is found to provide evidence of conformance, the releasing device assembly may be recognized for approval and listing.

  INSTRUCTIONS

  Sec. 12-10-301. Approved installation instructions shall be provided by the manufacturer. Instructions shall be illustrated and shall include directions and information adequate for obtaining proper and safe installation of the equipment.

  DESIGN

  Sec. 12-10-302.

  (a) Releasing pressure. Exit panic hardware mechanisms shall be designed to release the door latch or latches when pressure not to exceed 15 pounds is applied at any point along the cross-bar perpendicular to the door in the direction of exit travel. The cross-bar shall extend across not less than one-half the width of the door.

  (b) Locking device. A locking device employed as part of the mechanism shall not prevent release of the door latch or latches when pressure of not to exceed 15 pounds is applied to the cross-bar in the direction of exit travel.

  (c) Dead locking bolt. A dead locking bolt shall not be provided as a part of the mechanism unless it is released and retracted, and does not prevent release of the door latch or latches, or release of the door to swing outward when pressure not to exceed 15 pounds is applied to the cross-bar in the direction of exit travel.
