What is UL 1462 ?

UL 1464 is a widely recognized standard in the electrical industry that pertains to the testing and certification of audible signaling devices. This technical standard was established by Underwriters Laboratories (UL) in 1988 and has undergone several revisions to ensure that it remains up-to-date with technological advancements.

The scope and coverage of UL 1464 are extensive, covering a wide range of audible signaling devices, including horns, sirens, bells, and alarms. The standard outlines the minimum requirements and test procedures that must be followed during the entire product development, testing, and evaluation process.

UL 1464 aims to ensure that these devices meet specific safety and performance criteria, allowing them to function effectively and reliably in various applications. The standard sets forth minimum requirements and test procedures that must be followed during product development, testing, and evaluation.

UL 1464 Testing Procedures

UL 1464 specifies a series of tests that must be performed on audible signaling devices to ensure that they meet the minimum requirements outlined in the standard. These tests include:

* Sound level testing: This test measures the sound level of the device, ensuring that it meets the required decibel level.

* Continuous wave (CW) testing: This test measures the device's ability to operate as a continuous wave (CW) signal, ensuring that it can operate reliably in various applications.

* Interference testing: This test measures the device's ability to operate in the presence of other signals, ensuring that it does not interfere with other systems.

* Temperature testing: This test measures the device's performance at different temperatures, ensuring that it meets the requirements at various operating temperatures.
