Basic Information
Scope
This document specifies the technical requirements for sound signaling devices for household and similar use, including their structure, mechanical performance, and electrical performance.
This document applies to sound signaling devices for household and similar use with a rated voltage not exceeding 250 V AC or 250 V DC, and a rated input power not exceeding 100 VA, which are equipped with an integral housing. It also applies to sound signaling devices intended to be installed in housings that comply with GB/T 17466 (all parts) or provided with such housings. In these sound signaling devices, indicator lights with a rated input power not exceeding 10 VA may also be included.
These products are referred to as "devices" in this document.
This document applies to fixed, mobile, and plug-in devices for indoor or outdoor use.
In special conditions, special structures may be required.
Note 1: This document can be used as a guide for the technical requirements of sound signaling devices with a voltage lower than 50 V AC or 75 V DC. Additional requirements for sound signaling devices with a voltage lower than 50 V AC or 75 V DC are currently under consideration.
Note 2: This document does not include radio transmission and reception functions.
