UL Fire Alarm Certifications
The audible sounder models that are powered using 24 Vdc input are Listed by Underwriters Laboratories (UL) for use
in fire alarm applications. The 120 Vac and 230 Vac inputs have not been evaluated. These models have the following
nomenclature: G-SND-MV-D, G-SND-MV-T, and G-SND-024-E. They have an electrical rating of 515 mA maximum at 24
regulated voltage Vdc (16 Vdc to 33 Vdc).
NOTE:
UL evaluated this product only to the stated operational voltage range. It was not evaluated to 80% to 110% of the
voltage range.
The sounder is factory set with the tone selector switch set to the No. 12 setting. This is a constant 1 kHz tone. This is
the only tone setting that has been evaluated for fire alarm applications. At this tone, the sounder has a sound pressure
level of 79.0 dB. See Figure 9 for the dispersion characteristics.
The units can be mounted on a wall or ceiling and have no mounting orientation restriction. For specific installation and
wiring requirements, refer to local codes such as the National Code (NFPA70) and the National Fire Alarm and Signaling
Code (NFPA72).
