Assembly, installation & actuator placement

CRSC Part 12 sets test, marking and installation rules for assemblies and actuators (see § 12-3-11, § 12-3-12 and § 12-3-13, including § 12-3-13.3).

Last reviewed: July 6, 2026

Overview

This area of the California Referenced Standards Code (CRSC) covers requirements for how prefabricated assemblies and their releasing devices are installed, marked and documented — with specific provisions for manual and automatic actuators used on security bars, releasing mechanisms and similar life-safety assemblies. The CRSC sets test, marking and installation expectations that work together with manufacturer instructions and listing requirements to ensure assemblies operate as intended in an emergency .

Proper installation matters because placement and mounting affect both occupant safety and code compliance: the building code requires installation in accordance with listings and the manufacturer’s instructions, and the CRSC requires installation/operation instructions and mounting limits for actuators to preserve reliable operation and accessibility . Key provisions to review in this area include the abuse and manual actuation tests in § 12-3-11, the marking requirements in § 12-3-12, and the installation and instruction requirements of § 12-3-13 (including the actuator mounting height in § 12-3-13.3) .

    ** The horizontal airflow, measured at a horizontal distance of 20 inches (0.5 m) from the edge of the wall assembly, shall not exceed 1.64 ft/s (0.5 m/s). 3. Placement of test frame. Prior to testing, and without the test specimen in place, position the frame assembly under the exhaust hood and set the gas burner for the prescribed level of output. 4. Placement of specimen. Once the burner output is verified, position the specimen holder assembly at the desired test location under the collection hood.

    1. Test specimen. Insert the test specimen into the frame assembly, sealing all edges with ceramic wool.
    2. Ignition. Simultaneously ignite the gas burner and start the timer marking the beginning of the test. Control the burner to a constant 150 ± 8 kW output. Control the hood duct flow to collect all products of combustion.
    3. Flame exposure. Continue the flame exposure until flame penetration of the test specimen and sustained flaming on the unexposed side occurs or for a period of 10 minutes, then extinguish the burner.
    4. Observation. If sustained flaming on the unexposed side of the test specimen has not occurred, observe the unexposed side of the test specimen for an additional 60 minutes for evidence of sustained flaming or glowing combustion on the unexposed side. Terminate the observation prior to the completion of the 60-minute observation period if all evidence of flame, glow and smoke has disappeared.

    Note: An infrared thermometer has been found to be useful to detect the increase of temperature on the unexposed side of the test assembly. 9. Documentation. Perform photographic and/or video documentation before, during and after each test.

    SANITARY DRAINAGE

    free of dirt, mud, sand, and foreign materials. Cut pipe shall be free from sharp edges. Fold and insert gasket into the hub. Lubricate the joint following manufacturer’s instructions. Insert spigot into hub until the spigot end of the pipe bottom out in the hub. Use the same procedure for the installation of fittings.

    A mechanical joint shielded coupling type for hubless cast-iron pipe and fittings shall have a metallic shield that complies with ASTM A1056, ASTM C1277, ASTM C1540, or CISPI 310. The elastomeric gasket shall comply with ASTM C564. Hubless cast-iron pipe and fittings shall be clean and free of dirt, mud, sand, and foreign materials. Cut pipe shall be free from sharp edges. Gasket shall be placed on the end of the pipe or fitting and the stainless steel shield and clamp assembly on the end of the other pipe or fitting. Pipe or fittings shall be seated against the center stop inside the elastomeric sleeve. Slide the stainless steel shield and clamp assembly into a position centered over the gasket and tighten. Bands shall be tightened using an approved calibrated torque wrench specifically set by the manufacturer of the couplings.

    705.3 Copper or Copper Alloy Pipe (DWV) and Joints. Joining methods for copper or copper alloy pipe and fittings shall be installed in accordance with the manufacturer’s installation instructions and shall comply with Section 705.3.1 through Section 705.3.4.

    705.3.1 Brazed Joints. Brazed joints between copper or copper alloy pipe and fittings shall be made with brazing alloys having a liquid temperature above 1000°F (538°C). The joint surfaces to be brazed shall be cleaned bright by either manual or mechanical means. Piping shall be cut square and reamed to full inside diameter. Brazing flux shall be applied to the joint surfaces where required by manufacturer’s recommendation. Brazing filler metal shall conform to AWS A5.8 and shall be

    applied at the point where the pipe or tubing enters the socket of the fitting.

    705.3.2 Mechanical Joints. Mechanical joints in copper or copper alloy piping shall be made with a mechanical coupling with grooved end piping or approved joint designed for the specific application.

    Notes

    1. Temporary Service Attachment

    Temporary services will not be directly attached to any structure considered by PG&E to be of inadequate strength. The structure must, in all cases, be substantial (see Note 2) and capable of supporting the service span, as well as the force of the ladder and worker against the service mast.

Frequently asked questions

Where must actuators be mounted?

Actuators must be mounted inside the room and not higher than 48 inches (1.2 m) above the finished floor, per § 12-3-13.3 of the CRSC .

What installation documentation is required?

Each system must be supplied with installation and operating instructions that describe initial testing, periodic testing/maintenance and, where components are provided separately, compatibility and sizing information, per § 12-3-13.1–13.2 .

Are actuators and assemblies required to be labeled?

Yes — security bars, latching mechanisms and manual actuators must carry permanent markings (manufacturer, model, date and operating symbols/diagrams) and listing identification as required in § 12-3-12 .
