What are the design requirements for alarm systems, occupant notification and EVAC/voice systems?
Plain‑English summary: The California Fire Code requires fire alarm systems to actually notify people — with specific sound levels, special tones in sleeping rooms, visible alarms where required, and emergency voice/paging systems in larger or high‑rise buildings — all designed per NFPA 72, monitored by an approved supervising station when required, and tested with documentation at completion.

What the code requires — 2-4 sentences
The California Fire Code requires fire alarm systems to provide timely occupant notification (audible and visible) and, where required, emergency voice/alarm (EVAC) systems designed and installed in accordance with NFPA 72. Key controlling provisions are § 907.5 (occupant notification), § 907.5.2.2 (emergency voice/alarm communication), § 907.6.6 (supervising‑station monitoring), and § 907.7 (acceptance testing and completion). These sections set minimum performance (sound levels, coverage, paging zones), monitoring, and testing/documentation requirements.
The single most important rule: fire alarm notification and EVAC/voice systems must be designed/installed per NFPA 72 and must actually notify occupants (audible/visible or voice) as required by § 907.5 and § 907.5.2.2.
Requirements in detail
Use the subsections below as a design checklist — each item is grounded in the CFC sections cited.
1) System design basis and shop drawings
- Fire alarm shop drawings must be prepared per NFPA 72 and submitted for review prior to installation; equipment must be listed/approved. See § 907.1.2 and related equipment requirements.
2) Activation, annunciation and general occupant notification (§ 907.5)
- Upon any required activation the system must initiate occupant notification and must annunciate at the fire alarm control unit or an approved constantly‑attended location per § 907.5.1. Presignal features are only allowed where approved and are specifically prohibited in some occupancies. § 907.5.
3) Audible notification (key performance numbers) — (parts of § 907.5.2)
- Audible appliances shall emit a distinctive fire alarm sound and shall not be used for other sounds. Audibility requirement: provide 15 dBA above average ambient or 5 dBA above maximum sound lasting ≥60 seconds, whichever is greater. Maximum total sound level shall not exceed 110 dBA at minimum hearing distance. These performance criteria are in § 907.5.2.1.1 and § 907.5.2.1.2.
- In sleeping rooms of Groups R‑1, R‑2 and I‑1, the alarm must be a 520‑Hz low‑frequency signal (or provide equivalent listed appliance) per § 907.5.2.1.3.1/1.3.2.
4) Visible notification and sleeping‑unit sizing (§ 907.5.2.3)
- Where visible alarms are required, provide visible appliance counts and placement per the code tables and subsections (including future capability requirements for many Group R occupancies). A specific sleeping‑unit table is given in § 907.5.2.3.2 (numbers of visible appliances by sleeping‑unit count).
Decision‑relevant table (quick reference)

| EVAC design standard | EVAC/voice systems must be designed & installed per NFPA 72 | § 907.5.2.2 |
| Monitoring required? | Fire alarms required by Chapter must be monitored by an approved supervising station (exceptions apply) | § 907.6.6 |
| Acceptance testing | System and components tested per NFPA 72; provide record of completion and as‑builts | § 907.7 |
5) Emergency voice/alarm communication (EVAC) — § 907.5.2.2 (design highlights)
- EVAC systems must be designed/installed per NFPA 72; activation by automatic detectors, sprinkler waterflow, or manual box shall automatically sound an alert tone followed by voice instructions for general or staged evacuation in accordance with the building’s fire‑safety/evacuation plan. § 907.5.2.2.
- Paging zones: at a minimum provide zones for elevator groups, interior exit stairways, each floor, and areas of refuge; speakers are required throughout the building by paging zones. Manual override (selective and all‑call) and capability for live voice paging are required. Standby power for EVAC is required (see code reference to Section 1203).
- High‑rise and Group I‑2 occupancies with floors >75 ft: the system must operate at least on the alarming floor, the floor above and the floor below.
6) Monitoring (supervising station) — § 907.6.6
- Fire alarm systems required by the chapter (or by the California Building Code) shall be monitored by an approved supervising station in accordance with NFPA 72. Exceptions include single/multiple‑station smoke alarms, some Group I‑3 detector supervision, and sprinklers in one‑ and two‑family dwellings. Transmission method and listing requirements must comply with NFPA 72 and the section. § 907.6.6 et seq.
- MIY (monitor‑it‑yourself) transmitters: direct transmission from MIY to a PSAP is not permitted unless approved by the fire code official. § 907.6.6.2.
- Special school requirement: Group E schools must transmit alarm, supervisory and trouble signals to an approved supervising station meeting listing requirements (see § 907.6.6.4).
7) Acceptance testing, record keeping and instructions — § 907.7
- After installation the fire alarm system and all components shall be tested in accordance with NFPA 72, each device (including single/multiple‑station alarms) shall be tested, a record of completion shall be provided, and operating/testing/maintenance instructions and as‑built drawings shall be left at an approved location. § 907.7 and subsections.
Exceptions & special cases
- Presignal features are restricted and not permitted in Group I‑2 or R‑2.1 occupancies. § 907.5.1.1.

Frequently asked questions
Who decides whether EVAC voice overrides other building paging?
The fire code official approves allowable alternative uses; however, the code requires that manual fire alarm use takes precedence over other uses of an EVAC/public‑address system (see § 907.5.2.2.3).
Is a supervising station always required?
No — § 907.6.6 requires supervising‑station monitoring for fire alarm systems required by the chapter, but there are explicit exceptions (single/multiple‑station smoke alarms, some Group I‑3, and sprinklers for one‑ and two‑family dwellings).
Do I have to use 520‑Hz in every alarm inside a hotel room?
Where the code requires a fire alarm system for sleeping rooms in Groups R‑1, R‑2 or I‑1, the 520‑Hz low‑frequency signal is required; if a smoke alarm cannot produce it, provide a listed notification appliance or detector with integral 520‑Hz sounder per § 907.5.2.1.3.
What must be on the project hand‑over after final testing?
A record of completion showing tests per NFPA 72, operating/testing/maintenance instructions, equipment specs, and record drawings (“as‑builts”) at an approved location as required by § 907.7.
Can EVAC/voice zones be used for non‑emergency paging?
Yes, but the EVAC system must have priority for manual fire alarm use and any other uses must be subordinate; the EVAC system is allowed to be used for other announcements provided fire alarm use takes precedence (see § 907.5.2.2.3).
