Single- and multiple‑station mechanically operated devices
Standard 12-72-2 of the CRSC sets the state minimums for design, testing and listing of mechanically operated single‑ and multiple‑station fire alarm devices and coordinates with Fire Code installation and testing requirements.
Last reviewed: July 6, 2026
Overview
This part of the California Referenced Standards Code (CRSC) contains Standard 12-72-2 and the minimum construction, performance and test requirements for single‑ and multiple‑station mechanically operated fire alarm devices intended for indoor installation. The scope and intent are set out in § 12-72-200, which defines the classification and applicability used by the State Fire Marshal for listing and approval.
The standard defines single‑station and multiple‑station devices (including gas‑operated and spring‑wound types), sets material, mounting, calibration and mechanical‑assembly requirements, and specifies test report and labeling expectations. Electrically operated single‑ or multiple‑station devices actuated by heat, smoke or combustion products are excluded from this mechanically operated standard; see the device coverage and definitions in §§ 12-72-201–12-72-202.
Compliance under Standard 12-72-2 is coordinated with installation, acceptance testing and maintenance requirements in the California Fire Code and NFPA 72 (for example Sections 907.2.11 and 907.7.1 for single/multiple‑station smoke alarms and acceptance testing). Practitioners should read §§ 12-72-200 through 12-72-202 together with the Fire Code acceptance and testing sections to ensure listed devices are installed and tested per state requirements.
In this section
- What are the temperature classifications and oven/fire-test methods for mechanical devices?
- What does the single- and multiple-station device standard cover?
- What endurance and operational tests (cycle counts, operation rates) are required?
- What test-report and instruction requirements apply to mechanically operated devices?

STATE FIRE MARSHAL
SCOPE
Sec. 12-72-200.
(a) Basic. This standard represents the minimum basic requirements for the construction and performance of single- and multiple-station fire alarm devices intended for indoor installation, and to be listed under this classification. The minimum design, construction and performance standards set forth herein are those deemed as minimum necessary to establish conformance to the regulations of the State Fire Marshal.
(b) Definitions. For the purpose of this standard, the following definitions shall apply:
Fire alarm device, multiple station. Two or more gas-operated single station units interconnected by metal tubing to one or more remote alarm-sounding devices.
Fire alarm device, single station. A self-contained fire alarm system comprising a heat detector, an alarm- sounding device and a stored energy source incorporated in one integral package. The basic types are gas- operated units and springwound units.
Gas-operated type. A device having a temperature-sensitive eutectic element; compressed gas, usually in a liquid state in a cylinder; and a sounding means, such as a horn or whistle. When the eutectic element melts, the compressed gas is released in a gaseous state through the alarm-sounding device.
Spring-wound type. A device having a temperature-sensitive bimetal or eutectic element and a spring-wound type mechanism with clapper mounted within a bell housing. The snap action of the bimetal or melting of the eutectic element releases the spring mechanism resulting in a bell-type sound.

12-3 RELEASING SYSTEMS FOR SECURITY BARS IN DWELLINGS
(This standard includes provisions of Underwriters Laboratories Subject 2326, Appendix B, dated December 17, 1999, reprinted with their permission.)
INTRODUCTION
SECTION 12-3-1—SCOPE
12-3-1.1 These requirements cover releasing systems for bars, grilles, mesh, glazing or other items intended to provide security at doors and windows required for emergency escape from dwelling units. 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.
Frequently asked questions
What devices are covered by this CRSC standard?
Standard 12-72-2 covers mechanically operated single‑station and multiple‑station fire alarm devices (gas‑operated and spring‑wound designs) intended for indoor use; see § 12-72-200 and the definitions in § 12-72-201.
Are electrically operated alarms included?
No. The mechanically operated standard explicitly does not cover electrically operated single‑ or multiple‑station devices actuated by heat, smoke or combustion products; refer to § 12-72-202(d).
How does this standard interact with the California Fire Code and NFPA 72?
The CRSC establishes device construction and performance for listing; installation, acceptance testing and ongoing maintenance follow the California Fire Code and NFPA 72 (see Fire Code Sections 907.2.11 and 907.7.1 for single/multiple‑station alarm installation and acceptance testing).
