Chapter 12-3 — RELEASING SYSTEMS FOR SECURITY BARS IN DWELLINGS

Section 12-3-4 — MATERIALS

2025 California Referenced Standards Code (Title 24, Part 12) · 2025 edition · updated 2026-07-29 · California

12-3-4.1 The materials employed shall have adequate mechanical strength to perform their expected function.

12-3-4.2 O-rings, gaskets and seals shall comply with UL Standard 157, 1996 Edition. Polymeric materials shall comply with UL Standard 746C, 1995 Edition, Section 25-27.

Exception: O-rings, gaskets, seals and polymeric materials that are used as decorative parts, or whose failure will not affect the ability of the system to comply with these requirements.

12-3-4.3 Components constructed of dissimilar metals shall not be used in applications where contact between them is likely to cause galvanic corrosion. The materials employed shall reduce the likelihood of the release mechanism becoming inoperative due to corrosion.

12-3-4.4 Ferrous metal parts shall be 300 series stainless steel or protected against corrosion using minimum G60 or A60 hot-dipped mil galvanization, 0.0104 mm thick zinc coating, 0.0127 mm thick cadmium coating or two coats of organic outdoor paint.

RELEASING SYSTEMS FOR SECURITY BARS IN DWELLINGS

12-3-4.5 Manual actuators.

12-3-4.5.1 Security bar releasing assembly mechanisms shall include a manual actuation mechanism that is capable of unlatching the security bars so that they can be opened by the occupants. The actuating force shall be applied in one of the following

manners:

Finger actuated: Pushing with the index finger or pulling a loop with the index finger in a curled position.

Hand actuated: Pulling, pushing, twisting, rotating or turning a lever, knob, handle, rod or similar actuator with the hand or multiple fingers.

Foot actuated: Kicking, depressing or stepping on an actuating pedal, lever, stirrup or similar actuator.

12-3-4.5.2 On foot-actuated systems, only a single foot motion shall be used to disengage the bar assembly from the latch. On finger- and hand-actuated systems, one or two distinct hand or finger motions shall be used to disengage the bar assembly from the latch.

12-3-4.5.3 Releasing the actuator after the latch has been disengaged from the bar assembly shall not reengage the bar assembly.

12-3-4.5.4 No features or methods shall be provided or referenced in the instruction manual to inhibit the operation of the releasing mechanism.

12-3-4.6 Cables and connectors.

12-3-4.6.1 Cables connecting actuators to latches and release mechanisms shall only be used in applications where the force transmitted by them during normal operation is less than [ 1] / 10 the manufacturer’s rated working tension or compression.

12-3-4.6.2 Cables and connectors shall not be damaged, or have wire strands frayed during normal installation or use, and shall not contact sharp objects when installed as intended.

12-3-4.6.3 The means used to secure cables or connectors to latches, release mechanisms and actuators shall provide a tight, reliable nonslip connection.

12-3-4.7 Hinges.

12-3-4.7.1 Hinges shall operate smoothly and reliably, and shall not be susceptible to rust or corrosion.
