UL Fire Alarm Certications
The audible sounder models that are powered using 24Vdc input are Listed by Underwriters Laboratories (UL) for use
in re 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 re 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 specic installation and
wiring requirements, refer to local codes such as the National Code (NFPA70) and the National Fire Alarm and Signaling
Code (NFPA72).
